|Name||Carboniferous marine rocks, unit 3 (SE California Clastic Assemblage)|
|Geologic age||Late Devonian to Early Permian|
Sedimentary > Carbonate > Limestone (Bed)Mississippian limestones include both fne-grained limestones of shelf facies and clastic limestones of deep-water turbidite facies; some are cherty. Pennsylvanian to Early Permian limestones are clastic limestones of deep-water turbidite facies
Sedimentary > Clastic > Mudstone > Shale (Bed)Black shale forms thick units of Late Mississippian age (primarily Rest Spring Shale)
Sedimentary > Clastic > Siltstone (Bed)Primarily quartzose siltstone to very fine grained sandstone of Mexican Spring Fm.
Sedimentary > Chemical > Chert (Bed)Thin-bedded, phosphatic chert is primary component of Late Devonian Squares Tunnel Fm (originally mapped as part of Mississippian Perdido Group)
Metamorphic > Metasedimentary > Metaclastic > ArgilliteSiliceous argillite of Squares Tunnel Fm.
Sedimentary > Clastic > Conglomerate (Bed)Mostly limestone and chert pebble conglomerate; boulder conglomerate locally at base of Kearsarge Formation
|Comments||Southeastern California clastic assemblage (northwestern Death Valley area). Consists primarily of Lower to Upper Mississippian limestone, Upper Mississippian shale, and Pennsylvanian to Lower Permian limestone (turbidite facies).Includes some rocks of Late Devonian age.|
|Stratigraphic units||Keeler Canyon Fm., Tihvipah Limestone, Rest Spring Shale, Perdido Group, Mexican Spring Fm., Leaning Rock Fm., Kearsarge Fm., Squares Tunnel Fm.|
