Bedded Barite Deposits in Sedimentary Environment: ABSTRACT

AAPG Bulletin, 1972
Bedded 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 ...

Depositional environment, age and facies of the Middle Triassic Bulog and rid formations in the Inner Dinarides (Zlatibor Mountain, SW Serbia): Evidence for the Anisian break-up of the Neotethys Ocean

, 2013
Below the Middle to lower Upper Jurassic ophiolitic melange and their overlying ophiolite nappes of the Dinaridic Ophiolite Belt in the Zlatibor Mountain area occur olistoliths and slideblocks.

Depositional environments in an arid, closed basin and their implications for oil and gas exploration: The lower Permian Fengcheng Formation in the Junggar Basin, China

American Association of Petroleum Geologists Bulletin, 2019
The Fengcheng Formation is a nonmarine, carbonate-dominated succession that formed under arid climatic conditions in a hydrologically closed basin. Two transects and two seismic profiles were examined, the characteristics and environmental significance ...

Ten placer deposit models from five sedimentary environments

Applied Earth Science, 2012
Placers 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).

The Saint Clair River Delta; sedimentary characteristics and depositional environments

Journal of Sedimentary Research, 1973
ABSTRACT 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 ...

Turbidite sedimentary structures and their relationship to proximal and distal depositional environments

Journal of Sedimentary Research, 1967
ABSTRACT The sand fraction of turbidites can be divided into three parts: from base upward the graded division (A), lower laminated division (B) and current rippled division (C). Some divisions may be missing in individual beds, which can thus start with either division A, B, or C.

Depositional Environments as Interpreted from Primary Sedimentary and Stratigraphic Sequences

1975
The focus of these notes is on the use of primary sedimentary structures and stratification sequence as tools for interpretation of depositional environment of clastic sediments, emphasizing advances in understanding that the authors judge to be important. To accomplish the primary objective, several topics have been selected.
