Environmental controls on sedimentary deposits in saline lake environments
2023Saline lakes are known to be sensitive to changes in environmental conditions on a broad temporal scale. Therefore, variations in the mineralogical, geochemical, and sedimentological characteristics of these settings have often been interpreted to reflect oscillations in climatic conditions. However, recent work has shown that microbial communities can

Sedimentary characteristics of abandoned-channel deposits in shallow tidal environments
2023Tidal channel networks control tide propagation and, therefore, fluxes of water, sediment, nutrients, and particulate matter in wetlands and low-lying coastal areas. Furthermore, tightly linked wetland-channel systems deliver multiple ecosystem services, among which blue carbon sequestration is critically important.

Ten placer deposit models from five sedimentary environments
Applied Earth Science, 2012Placers deposits are now known from five sedimentary environments; washout, river, aeolian, beach, and continental shelf. In each environment, the concentration of mineral grains, or sorting, takes place either by removal of gangue grains (denudation) or by addition of valuable grains (accumulation).

Bedded Barite Deposits in Sedimentary Environment: ABSTRACT
AAPG Bulletin, 1972Bedded deposits of barite are supplying an increasingly large part of the world's barite production, which is now nearly 4 million tons annually. A fourfold increase in the past 25 years is due chiefly to its use in drilling mud. Bedded deposits will continue to increase in commercial importance because many contain millions of tons of high-grade ...

Facies and Depositional Environments of Miocene Sedimentary Rocks
1994The area of the Bekes basin began to subside in early Badenian time during the late Styrian orogenic phase. The initial phase of subsidence and transgression of the Paratethys Sea is marked by conglomerate and/or breccia that is present almost everywhere where Miocene deposits occur.

Depositional Environments and Sedimentary Processes in Chile Trench: ABSTRACT
AAPG Bulletin, 1983The Chile Trench is a long, linear basin that concentrates clastic End_Page 557------------------------------ terrigenous material at the foot of the Andean continental margin. In southern Chile, high rainfall and river runoff, combined with intense Pleistocene glacial activity, transport large volumes of detrital sediment to the offshore regions ...

The Saint Clair River Delta; sedimentary characteristics and depositional environments
Journal of Sedimentary Research, 1973ABSTRACT Progradation of the northeastern shoreline of Lake St. Clair by the St. Clair River has created a modern, freshwater delta with a birdfoot configuration similar to that of the Mississippi deltaic plain. Textural parameters based on moment measures for surface sediments collected at 231 stations located on 78 square miles of the exposed and ...
