Abstract
The Jiashi area is located in the southwestern Tianshan tectonic belt, within the northwestern margin of the Tarim basin. In this study, which was based on the Jiashi Tonghui copper drilling data, a large number of field measurement data profiles, as well as the particle size analysis of thin samples, were collected. Sedimentology, stratigraphy, and many other integrated technologies and methods were utilized for the purpose of analyzing the depositional environment and phase of the Jiashi area, as well as to identify the fan delta, mesalagoon phase, tidal flat, braided river delta plain facies, and braided river delta front. A total of five types of sedimentary facies and a variety of sedimentary sub-phases were identified. The depositional environment of the study area has overall undergone several transgressive regressions. In this paleo-climate, the plaster layers of gypsum veins clearly reflected the arid environment.
