Geologic units containing Lake or marine sediment

  1. Earth material
  2. Unconsolidated material
Lake or marine sediment
A sedimentary deposit laid down conformably on the floor of, or along the shore of, a lake, sea, or ocean, usually consisting of coarse material near the shore and sometimes passing into clay and limestone in deeper water...
This category is also used for lake or marine deposit (non-glacial) and Lake sediments.

California

Quaternary alluvium and marine deposits (Pliocene to Holocene)
Alluvium, lake, playa, and terrace deposits; unconsolidated and semi-consolidated. Mostly nonmarine, but includes marine deposits near the coast.
 Quaternary sand deposits, unit 2 (inland) (Quaternary)
Extensive marine and nonmarine sand deposits, generally near the coast or desert playas

Idaho

Gravel, sand, silt, clay; Late Pleistocene glacio-alluvial and lacustrine deposits; Basin and Range, and Snake River Plain (Late Pleistocene)
Upper Pleistocene deposits; outwash, fanglomerate, flood and terrace gravels.
 Silt, clay, and diatomite; Middle Pleistocene lacustrine sediments of lava-dammed lakes; western Snake River Plain (Middle Pleistocene)
Middle Pleistocene lava-dammed Snake Plain lake beds of silt, clay and diatomite.
 Silt, clay, sand, and gravel; Quaternary-Tertiary alluvial and lacustrine deposits; western Snake River Plain (Early Pleistocene and Late Pliocene)
Pleistocene and Pliocene stream and lake deposits.

North Carolina

Surficial Deposits, Undivided (Quaternary)
Surficial Deposits, Undivided - sand, clay, gravel, and peat deposited in marine, fluvial, eolian, and lacustrine environments. Quaternary deposits not shown at altitudes greater than approx. 205 feet above mean sea level (Suffolk Scarp, in part).

New Mexico

lacustrine and playa-lake deposits (Phanerozoic | Cenozoic | Quaternary)
Lacustrine and playa-lake deposits; includes associated alluvial and eolian deposits of major lake basins; upper Quaternary

Nevada

Alluvial deposits (Quaternary)
ALLUVIAL DEPOSITS-Locally includes beach and sand dune deposits
 Older alluvial deposits (Miocene to Quaternary)
OLDER ALLUVIAL DEPOSITS
 Sedimentary rocks (Pliocene to Quaternary)
SEDIMENTARY ROCKS-Mostly lake deposits

Utah

Tertiary (4) sedimentary rocks in Salt Lake City-Coalville-Randolph region (Middle Miocene to Late Pliocene)

Washington

Older glacial drift (Pleistocene)
Till, outwash, and associated interglacial deposits; sorted and unsorted gravel, sand, silt, and clay. Includes peat beds and non-glacial sediments locally. Mostly pre-Wisconsin in age.
Quaternary nonmarine deposits (Pleistocene)
Periglacial lacustrine deposits. Light-brown, well-sorted and bedded clayey sandstone and sandy clay with interbeds of volcanic ash and calcareous cemented gravels.

Wyoming

Playa lake and other lacustrine deposits (Phanerozoic | Cenozoic | Quaternary | Pleistocene Holocene)
PLAYA LAKE AND OTHER LACUSTRINE DEPOSITS--Chiefly clay, silt, and fine sand. Includes travertine deposits.
