Limestone, arenite, dolostone, chert, siltstone, shale; Upper Paleozoic marine continental-shelf deposits; southeastern Idaho (IDPZu;0)

State	Idaho
Name	Limestone, arenite, dolostone, chert, siltstone, shale; Upper Paleozoic marine continental-shelf deposits; southeastern Idaho
Geologic age	Late Paleozoic
Original map label	PZu
Comments	PZu on state map matches PZu on Pocatello quad. The map explanation names stratigraphic units, but shows no boundary between PZu and PZl. On the map Ordovician (but not Devonian) units extend to the boundary of PZl undivided. Also, the base of the Devonian is at the midpoint of the time span of the Paleozoic Era (208 Ma).
Primary rock type	limestone
Secondary rock type	arenite
Other rock types	dolostone (dolomite); chert; siltstone; shale
Lithologic constituents	Major Sedimentary > Clastic > Sandstone > Arenite (Bed) Sedimentary > Carbonate > Limestone (Bed) Minor Sedimentary > Carbonate > Dolostone (Bed) Incidental Sedimentary > Clastic > Mudstone > Shale (Bed) Sedimentary > Clastic > Siltstone (Bed) Sedimentary > Chemical > Chert (Lense)
