development in Alaska and is the site of the Matanuska Valley colony, established in The principal communities are Palmer and Wasilla. Eugged mountains flank the lowland on the north and south. The mountains adjacent to the Matanuska Valley range as high as – m and are composed dominantly of crystalline (igneous and metamorphic) rocks of Mesozoic age, overlain by Tertiary sedimentary rocks (Barnes, ).

Glacial deposits and fluvial deposits thus have clasts that reflect a highly varied source lithology. Matanuska Valley, Alaska:A Lower Jurassic flora from the upper Matanuska Valley, Alaska The concentration of boulder-rich mass-flow deposits in the footwall of the fault in.

The Matanuska valley coal field in southern Alaska is a northeast extension of the Cook Inlet basin, which contains the Paleocene coal-bearing Chickaloon Formation.

The coal field is bounded to the north by the Castle Mountain fault and Talkeetna Mountains and to the east-southeast by the Border range faults and Chugach Mountains. Surprisingly, loess deposits securely dated to the last glacial period are rare in Alaska, and paleowind reconstructions for this time period are limited to inferences from dune orientations.

We report a rare occurrence of loess deposits dating to the last glacial period, ~19. Alaska designated Jade as its official state gem in Alaska has large deposits of the gem, including an entire mountain of jade on the Seward Peninsula. A famous, remote, Arctic interior jade locality with an extensive history is the Jade Creek and Jade Mountain locality, Kobuk River region, in northwestern Alaska.

The Matanuska Valley project will investigate the paleoecology and paleoclimatology of an important late Paleocene-early Eocene sedimentary sequence in south-central Alaska’s Matanuska Valley. We will focus our studies on sedimentary facies analysis, sedimentary petrology, paleoclimatic reconstructions, studies of fossil wood, fossil insect-bearing amber deposits, and.

Upper Cretaceous sedimentary strata exposed in south-central Alaska provide insight on tectonic processes that shaped the northern Pacific margin following accretion of the Wrangellia composite terrane, the largest addition of crust to North America over the past m.y. Sedimentologic, geochronologic, biostratigraphic, and petrographic data from the Matanuska Formation permit.

In the Matanuska Valley and the Anchorage area, rivers and glaciers left large sedimentary deposits that provide an inexpensive source of sand and gravel.

After World War II, the city of Anchorage grew quickly, and it therefore needed building materials. The Matanuska Valley is a part of the lowland lying north of the Chugach Mountains in south-central Alaska (fig. 1 and pi. The valley of the Matanuska River and the lowland extending westward from it to the Susitna River are in the Matanuska and Wasilla.

The volcanogenic nature of the Sterling Formation is thought to result from erosion of older volcanic rocks and coeval arc volcanism in the Alaska‐Aleutian Range, as well as possible contributions from recycling of older fore‐arc basin strata in the exhumed Matanuska Valley.

These deposits occur in all parts of the Territory, from Pacific to Arctic oceans, the least favored section being the islands of the southeastern portion, where the deposits are of limited extent. The higher grade finds are in the Bering field near Controller Bay, and those in the Matanuska Valley, north of Seward.

The geology of Alaska includes Precambrian igneous and metamorphic rocks formed in offshore terranes and added to the western margin of North America from the Paleozoic through modern times. The region was submerged for much of the Paleozoic and Mesozoic and formed extensive oil and gas reserves due to tectonic activity in the Arctic Ocean.

Alaska was largely ice free during the Pleistocene. Sedimentary rocks, undivided Widely distributed around Alaska, unit typically consists of nonmarine, moderately to poorly consolidated deposits of variable composition that range from conglomerate to sandy gravel, gravelly sand, sand, and pebbly mud.

Lake - Lake - Sediments and sedimentation: Lake sediments are comprised mainly of clastic material (sediment of clay, silt, and sand sizes), organic debris, chemical precipitates, or combinations of these.

The relative abundance of each depends upon the nature of the local drainage basin, the climate, and the relative age of a lake. The sediments of a lake in a glaciated basin, for example.
