Depositional environment and thermal maturity of the coal-bearing Longtan Shale in southwest Guizhou, China: Implications for shale gas resource potential

, 2020
Significant knowledge has been assembled on the marine Longmaxi Shale in the Sichuan Basin over the past ten years. However, the distribution of shale gas resources on the periphery of the Sichuan Basin and in other source rock formations are still not ...

Deposit Insurance in a Deregulated Environment

The Journal of Finance, 1984
THE UNITED STATES has had a federal deposit insurance system for half a century. This system has been an unparalleled success in the sense that it has virtually eliminated "runs" on financial intermediaries. However, the deregulation legislation of 1980 and 1982, as well as the market forces which spawned this legislation, have raised serious questions

Depositional environment and organic matter enrichment of the lower Cambrian Niutitang shale in western Hubei Province, South China

Marine and Petroleum Geology, 2019
It is important to consider the influences of depositional environment on lithofacies characteristics, lithofacies distribution patterns, and organic matter enrichment when defining reservoir properties and predicting “favorable reservoirs” and “sweet ...

Effects of depositional environment and organic matter degradation on the enrichment and mobilization of iodine in the groundwater of the North China Plain.

Science of the Total Environment, 2019
Groundwater iodine has direct importance for human dietary iodine intake in areas where drinking water is of groundwater origin. However, little is known about enrichment and mobilization mechanisms of groundwater iodine in the North China Plain (NCP ...

Environment of Sediment Deposition

2017
Grain size of sediments relates to the physical characteristics of the depositional environments. The distribution of sediment grain size is affected by the variations of wave energy and turbulent conditions of depositing environment. Linear Discriminate Analysis (LDA) technique and bi-variate plotting of grain size parameters are used to explain and ...

Climate-Driven Variations in the Depositional Environment and Organic Matter Accumulation of Lacustrine Mudstones: Evidence from Organic and Inorganic Geochemistry in the Biyang Depression, Nanxiang Basin, China

Energy & Fuels, 2019
The influence of the paleoclimate on the organic matter (OM) accumulation and depositional process in the third member of the Hetaoyuan Formation shales is unclear in the Paleogene lacustrine systems in the Biyang Depression, Nanxiang Basin, Eastern ...

Facies analysis and depositional environment of the Campano – Maastrichtian coal-bearing Mamu Formation in the Anambra Basin, Nigeria

Journal of African Earth Sciences, 2019
Detailed sedimentological logging was carried out within the exposed rock sections of the late Campanian to early Maastrichtian successions of the coal-bearing Mamu Formation, southeastern province of Nigeria. Lithofacies analytical approach was employed
