The Microfacies analysis of the Cretaceous Mishrif Formation was studied in Nasiriyah oil field Governorate, southern Iraq using integrated borehole data set that included, core samples and well logs newly drilled to analyze microfacies Diagenesis Process formation, 100 thin sections for selected well. results show formation composed of: (top base) a fine-grained, limonitic fresh water limeston...

Salinized lake basins have distinctive sedimentary response characteristics, similar to marine shallow-water carbonate platforms. High-frequency cycles can also be used reveal more sedimentological information, such as relative lake-level fluctuations, lithofacies sequence combinations, and paleogeographic evolution. In this article, a comprehensive study on the stratigraphic shelf delineation ...

Previously conducted studies have established that gaseous water sorption of mudstone is widespread in nature. The deterioration its uniaxial compression properties during can cause engineering problems. However, related were currently the initial stage this research direction. On one hand, there few on characteristics process. results might not be applicable to all projects. other microstructu...

Earth scientists are often asked to establish or constrain the likely provenance of very small quantities of earth-related material as part of a forensic investigation. We tested the independent and collective interpretations of four experts with differing analytical skills in the prediction of sample provenance for three samples from different environmental settings. The methods used were X-ra...

We describe the physical context of the Dinaledi Chamber within the Rising Star cave, South Africa, which contains the fossils of Homo naledi. Approximately 1550 specimens of hominin remains have been recovered from at least 15 individuals, representing a small portion of the total fossil content. Macro-vertebrate fossils are exclusively H. naledi, and occur within clay-rich sediments derived f...

A remote sensing image is composed of vegetation and base rock or soil in moutain areas, which can be decomposed by the fractal model through Fourier transformation to enhance base rock or soil information. In this paper, four scene images of two types of bed rock from Anhui province are taken as a case to demonstrate the method’s validity: two scene images’ base rocks are monzonite granite whi...
