Table DR 1: Formal Description of New Units Defined in the Publication
All of the units defined here are exposed in core obtained from deep wells in and around the
Savannah River Site. Core is stored at the SRS Core Repository. Well locations are shown in
figure 3 of this report, and below in the Savannah River Site grid system.
Crackerneck Metavolcanic Complex
Cores which sample the Crackerneck metavolcanic complex were drilled to study the
overlying sedimentary fill, and generally do not penetrate deeply into the underlying basement.
As a result, we present two “type sections” here: one for mafic Crackerneck and one for felsic
Crackerneck. Older core obtained from this unit (e.g., the “P” series wells) is 4 inches in
diameter; more recent core is 1 inch.
Rocks comprising the northern portion of the Crackerneck metavolcanic complex of the
Savannah River Site are dominantly intermediate to felsic tuffs and lapilli tuffs. Core from the
southern part of the subcrop area is dominanted by greenstone and mafic tuff. Low-grade
metavolcanic rocks of the Crackerneck metavolcanic complex are penetrated by younger granitic
intrusions, including the Devonian Springfield granite and the Carboniferous Graniteville granite
(figure 2).
Type section: Core P30; Northing: 3688762.7, Easting: 43053.53, Total Depth: 810 feet.
Description, footage 780-796: Pale grey felsic tuffs with visible relict lapilli are composed of
small quartz and plagioclase grains with plagioclase phenocrysts. All plagioclase grains have
been metamorphosed to nearly pure albite, but relict igneous textures are well preserved. Felsic
rocks may also contain small amounts of muscovite and epidote, but generally do not display the
intensely chloritized or epidotized appearance.

Reference section (felsic): Core MMP4; Northing 434068.64, Easting 3688771.48, Total Depth:
785.0 feet.
Description, footage 785: Lapilli tuffs display large (to 1.5 x 5 cm) flattened and elongated pumice
lapilli giving an appearance similar to lapilli tuffs of the Persimmon Fork Formation.
Reference section (mafic): Core P6R; Northing: 3682009.2, Easting: 431351.37, Total Depth:
1042 feet.
Description, footage 837-862: Dark grey-green mafic metavolcanic rock are composed of
chlorite, plagioclase, epidote and opaque minerals. Lapilli vary from equant clasts to epidotized
clasts to wispy, white, pumiceous (?) clasts.
Deep Rock Metaigneous Complex
Consists of two subunits: the Deep Rock Metavolcanic Suite and the DRB Metaplutonic
suite. All DRB (Deep Rock Borehole) core is 4” in diameter. Because basement was the target of
this core series, thousands of feet of core are available for study. Each suite has separate
reference sections as listed below.
Deep Rock Metavolcanic Suite
Type section: Core DRB-5; Northing: 3683425, Easting: 438804, Total Depth: 1838 feet.
Description, footage 1300-1838: Metavolcanic rocks display a wide array of textures,
compositions, and mineralogy. Textures include (a) aphyric intermediate tuffs and mafic, chloritic
schists, (b) plagioclase-phyric tuffs and schists, and (c) hornblende-phyric tuffs and schists.. Mafic
metavolcanic rocks consist of metamorphic blue-green amphibole, plagioclase, quartz, epidote,
and chlorite, with or without relict, brown igneous hornblende. Felsic and intermediate
metavolcanic rocks consist of plagioclase, quartz, epidote, biotite, and chlorite, ±amphibole and
rare garnet. These mineral assemblages are consistent with lower amphibolite or uppermost
greenschist facies metamorphism.

Plagioclase phenocrysts display various stages of metamorphism. Many plagioclase
phenocrysts form subhedral to euhedral crystals that preserve primary igneous compositions and
zoning. Other plagioclase grains are anhedral, albitized porphyroclasts that have been partially to
extensively epidotized.
Hornblende phenocrysts range from blocky, subhedral crystals to elongated, prismatic
crystals. Relict igneous hornblende phenocrysts are brown in thin section. In many samples,
hornblende phenocrysts and groundmass hornblende have been largely metamorphosed to bluegreen amphibole. Amphibole is commonly retrograded to chlorite in varying degrees, and some
segments of core have undergone complete chloritization of the mafic minerals. Intermediate to
felsic metavolcanic rocks commonly contain biotite, which is commonly partially chloritized,
and a few contain garnet.
Metaigneous dikes are common in core. These dikes, which crosscut the metavolcanic rocks,
are generally unfoliated, but in many places exhibit the same asymmetric folding apparent in the
foliated metavolcanic rocks. There are three groups of dikes: (a) aphyric mafic dikes with
basaltic compositions; (b) plagioclase-phyric mafic dikes with basaltic compositions; and (c)
aphyric felsic dikes with rhyolitic compositions. Plagioclase-phyric mafic dikes are characterized
by large, euhedral plagioclase phenocrysts that preserve relict primary zoning, within a
groundmass of amphibole, plagioclase, epidote, chlorite, and biotite. The aphyric mafic dikes are
identical to the plagioclase phyric dikes, but lack the conspicuous large phenocrysts. The
groundmass of these dikes contains significantly less chlorite and epidote than their metavolcanic
host rocks. The felsic dikes consist of fine-grained plagioclase and quartz, with minor opaque
oxides, biotite, and hornblende.

All rocks have been overprinted with a penetrative fabric (foliation) that dips §40˚ to 60˚
assuming core is vertical, but the strike and dip direction are not known. Extensive transposition
of layering is evident on the mescoscopic and microscopic scales. Rootless, intrafolial isoclines
are commonly observed. Asymmetric folds of foliation have long limbs dipping up to 60° and
short limbs that can be nearly horizontal. These folds have a typical “down dip” vergence. Fold
axes are subhorizontal (assuming core is vertical). Mafic phyllonites are commonly observed that
indicate dextral motion and/or “hanging wall up” motion. Chloritic fractures that have the same
strike as foliation and dip less steeply than foliation are ubiquitous. Offsets of metamorphic
layering are discernible, but the sense of offset is not always clear.
Reference section #1: Core DRB-3; Northing: 3682954, Easting: 438181.8, Total Depth: 1928
feet.
Description, footage 950-1500: Dark grey-green mafic metavolcanic rock includes
porphyritic and equigranular fine-grained mafic schists, and porphyroclastic greenstones
amphibolites cut by metamorphosed mafic dikes, locally, phyllonitic zones crosscut this package.
Because some texturally similar black amphibolites are also dispersed throughout the section,
“green rocks” are interpreted to represent heterogeneous retrogression. Approximately 20% of
the section comprises a light gray felsite.
Down dip vergent asymmetric folding of foliation (long limb typically dipping 50-60°) and
dike is commonly observed. Dextral and hangingwall up shear sense indicators include shear
bands and winged porphyroclasts. Chloritic fractures that have the same strike as foliation and
dip less steeply than foliation are ubiquitous. Offsets of metamorphic layering are discernible,
but the sense of offset is not always clear.
Reference section #2: Core DRB-6; Northing: 3683130, Easting: 439247.2, Total Depth: 1913
feet.

Data Repository item 2004074
A.J. Dennis, J.W. Shervais, J. Mauldin, H.D. Maher, Wright, J.E.
Description, footage 1100-1913: Mafic (25%) and intermediate to felsic (75%) schists and
amphibolite facies gneisses. Mafic layers are commonly porphyritic with amphibole or
plagioclase porphyroclasts. Layering is heterogeneous in these mafic and felsic rocks.
Transposition of layering is evident from the mesoscopic to microscopic scales. Less sheared
bands of black amphibolite are separated by mylonitic mafic schists and phyllonite. Dips of
foliation are generally 70°. Detached rootless isoclinal folds are transposed into the plane of
foliation. Foliation is folded into downdip vergent asymmetric folds with near horizontal hinges.
Chloritized shear bands dip less steeply than foliation, and typically yield dextral or hanging wall
up shear sense.
Reference section #3: Core DRB-7; Northing: 3682833, Easting: 439474, Total Depth: 1868.8
feet.
Description:
footage 1300’-1868’: Heterolithic mafic schist interleaved with a fine grained
muscovite schist. Over the length of the section approximately half is mafic and half felsic. Some
of the distinctive lithic types within the mafic section are a greenstone, an amphibole porphyry,
and a banded amphibolite with large (<1 cm) garnets. Black amphibolites are separated by
mylonitic mafic schists. The section is extensively transposed. Rootless isoclines of layering and
foliation are folded asymmetrically with subhorizontal hinges and down-dip vergence. Felsic
schists commonly show a button schist texture, and shear bands indicate either hanging wall up or
dextral motion typically.
DRB1 Metaplutonic Suite
Named for the DRB-1 well in which it occurs.
Type section: Core DRB-1; Northing: 3684171, Easting: 437524.7, Total Depth: 1904 feet.
Description, footage 892-1904: The protolith for metadiorite and metaquartz diorite gneiss
were equigranular diorites and porphyries of hornblende phenocrysts in finer-grained,
5

groundmass of quartz, plagioclase, amphibole, and chlorite. These rocks cut minor intercalated
metavolcanic rocks, and are weakly metamorphosed with minor shear zones. Diorite and quartz
diorite sheets intrude preexisting, foliated metavolcanic wallrock. The diorites were
metamorphosed to epidote-amphibolite facies assemblages. These rocks are variably deformed
from undeformed to gneissic. The porphyritic gneisses are characterized by large, zoned
hornblende and plagioclase porphyroclasts, within a fine to medium-grained matrix of
plagioclase, quartz, chlorite, blue/green amphibole, and epidote. Chloritic fractures and
chloritized amphiboles may also appear sparsely.
Plagioclase porphyroclasts may show relict igneous features, including oscillatory zoning
and albite twinning. Metaplutonic rocks of DRB1 contain no garnet, consistent with
metamorphism at relatively low temperatures and pressures (lower amphibolite to uppermost
greenschist facies conditions). Biotite is rare to absent in the DRB1 metadiorites; almost all
primary biotite has been metamorphosed to chlorite.
Most amphibole porphyroclasts, and essentially all groundmass amphiboles, are
metamorphosed to blue-green amphibole. However, many amphibole porphyroclasts preserve
cores of brown hornblende, which are interpreted to represent relict igneous hornblende.
Metaplutonic rocks contain xenoliths and screens of amphibolite facies metavolcanic rocks
that are deformed and contain fabric elements similar to rocks of the Deep Rock Metavolcanic
Suite, with which they are assumed to correlate. These metavolcanic rocks are composed of
~60% blue/green amphibole and ~40% plagioclase, epidote, and quartz. The amphibole forms
small prismatic grains, plagioclase and epidote form blocky anhedral grains.
Thin anastomosing mylonite zones penetrate the DRB1 metadiorites. These may be
distinguished by belts of ultrafine-grained quartz, feldspar, amphibole, and epidote bounded on

either side by fine to medium grained porphyritic gneisses. The mylonite zones are generally
meter scale or thinner in thickness. Chloritic fractures are common in these metaplutonic rocks.
Pen Branch Metaigneous Complex
Consists of two subunits: the Pen Branch Metavolcanic Suite and the PBF Metaplutonic
suite. Each suite has separate reference sections as listed below.
Pen Branch Metavolcanic Suite
Type section: Core PBF-7; Northing: 3678485, Easting: 442463.6, Total Depth: 3651 feet.
Description, footage 2500 to 3500: Grey-green mafic metavolcanic rock forms rare screens
between sheets of unpinked and partly pinked granodiorote gneiss (PBF Plutonic suite) . Screens
are often black, but may have a conspicuous greenish cast.
Description, footage 3500 to 3600: Pinked granitic gneiss (PBF Plutonic suite).
Description, footage 3600 to 3648: Fine grained black amphibolite, commonly with garnet (up to 1
cm diameter) , locally retrogressed to a chlorite actinolite schist. Garnetiferous layers are generally
less than 7 cm thick.
Reference section #1: Seismic Attenuation Core; Northing: 3679655
Easting: 440618, Total
Depth: 4002 feet (PBF Plutonic Suite in continuous core above 1118 feet; spot cores from 19594002 feet). Description: footage 1959-4002: Migmatitic amphibolite, cut by undeformed pink
granite veins.
PBF7 Metaplutonic Suite
Named for the PBF7 and PBF well series in which it principally occurs. All PBF core is 2.5” in
diameter.
Type section: Core PBF-7, Northing: 3678485
Easting: 442463.6, Total Depth:
Description, footage 2550 to 3100: Unpinked, foliated granodiorite gneiss. Gneissic
metagranitoids are porphyroclastic gneisses with porphyroclasts of amphibole and plagioclase set
in a groundmass of amphibole, plagioclase, microcline, biotite, quartz, and epidote. Amphibole

porphyroclasts are unzoned blue-green amphiboles. Garnet porphyroblasts are a common
accessory mineral in the metaplutonic rocks.
Description, footage 3140 to 3480: Transition zone, unpinked granodiorite and diorite gneiss
with some partly pinked granodiorite gneiss.
Description, footage 3500 to 3600: Pinked granitic gneiss. Lower contact at 3600 feet is mylonite
zone which separates PBF plutonic suite from high-grade metavolcanic rocks of the Pen Branch
Metavolcanic Complex.
Pinked metagranitoid: “Pinked” PBF metagranites commonly contain large plagioclase,
microcline, and garnet porphyroblasts set in a finer-grained matrix of quartz, plagioclase,
microcline, and chlorite. Plagioclase porphyroclasts are much less common in pinked rocks.
Amphibole is almost completely chloritized, and with increasing pinking is increasingly
uncommon, but some relict blue-green amphibole is preserved. Microcline in the pinked
metagranitoids commonly occurs as large megacrysts up to ~5mm across, and may account for
as much as 40% of the modal mineralogy. Plagioclase in the thoroughly pinked granites is
completely albitized, and subsequently, partially sericitized. Biotite, like amphibole, also has
been almost completely chloritized. Pinking occurs on scales from mm-scale to dozens of meters
of complete alteration.
Reference section #1: Seismic Attenuation Core, Northing: 3679655
Easting: 440618
Description, footage 1078-1118: Pinked granitic gneiss. Lineated garnetiferous felsic gneiss and
felsic mylonite cut by coarse grained granitic veins. Large K-feldspar porphyroblasts in felsic
gneiss. Gneiss and granite have a conspicuous pinkish cast.
