Geological conditions and gas-bearing evaluation of the Niutitang Formation shale in the Xixiang–Zhenba area, China [PDF]

Geologia Croatica, 2020
Black carbonaceous shale of the Niutitang Formation in the Xixiang–Zhenba area was found to be well developed and abundant in high-quality shale gas. However, few studies have been conducted in this area, and its reservoir-forming conditions are not clear.

Enrichment Mechanism of Polymetallic Elements at the Base of the Niutitang Formation in Southeast Chongqing

Minerals
Polymetallic enrichment layers are commonly found at the base of the Lower Cambrian and extensively distributed across the Upper Yangtze Platform, yet their genetic models remain controversial. This study systematically collected samples from a typical section in the southeastern Chongqing region for mineral, organic, and inorganic analyses.

Application of Temperature Programmed Oxidation‐Infrared Technique in the Analysis of Sulfur Occurrence and Genesis in Phosphate Rock [PDF]

Journal of Analytical Methods in Chemistry, Volume 2022, Issue 1, 2022., 2022
In this study, a temperature programmed oxidation‐infrared (TPO‐IR) technique was improved and applied in the analysis of sulfur occurrence and genesis in phosphate rock. Phosphate rocks from three regions (KYP, ZJP, and WAP) were selected for the detection of sulfur species by TPO‐IR combined with XRD, SEM, EDS, and XPS characterization.
