Early Jurassic
174.1 - 201.3 Ma

ID: 2455964
Sander Basalt

Age: Early Jurassic (174.1 - 201.3 Ma)

Stratigraphic Name: Sander Basalt

Description: Dark-gray to bluish-gray, fine- to medium-crystalline, porphyritic to equigranular basalt with plagioclase, augite, and pigeonite phenocrysts; locally vesicular and amygdaloidal at tops of flows. Very poorly exposed and deeply weathered; forms low rolling hills; at least six to more than a dozen separate flows. Lower and upper flows of high-titanium, high iron, quartz normative basalt with middle flows of low-titanium, quartz normative basalt separated by several poorly exposed, lenticular, reddish-brown sandstone and siltstone (Jss). Basalts are characterized by distinctive curved columnar joints locally overprinted by closely spaced fractures; contacts poorly exposed but apparently paraconformable with underlying and intercalated sedimentary rocks; estimated maximum thickness 751 m (2465 ft), of which collectively about 205 m (675 ft) are interbedded sandstone and siltstone.

Comments: black; Dominant flow (bedding) folation; No fossils; basalt lava flows; used for aggregate

Lithology: Basalt

Early Jurassic
174.1 - 201.3 Ma

ID: 2768183
Newark Supergroup; Jurassic Basalt

Age: Early Jurassic (174.1 - 201.3 Ma)

Stratigraphic Name: Newark Supergroup

Description: Fine- to medium-crystalline, equigranular, porphyritic, vesicular, or amygdaloidal; medium- to dark-gray subophitic intergrowths of plagioclase laths and clinopyroxene with amygdules of calcite, zeolites, and prehnite. Occurs only in the Culpeper basin as three principle basalt flows separated by sedimentary rocks.
