Analysis of Neogene provenance in Zhahaquan area, Qaidam Basin

地质科技通报, 2023
It is generally believed that the provenance of the Neogene sandbar reservoir in the Zhahaquan Oilfield in the western Qaidam Basin is consistent with that of the Paleogene. However, existing studies present different opinions on the provenance during the Paleogene, which makes the provenance of the Neogene unclear and affects the study of sedimentary ...

Petrologic and geochemical characteristics of high-quality saline lacustrine source rocks in western Qaidam Basin

Petroleum Research, 2018
The main oil source in western Qaidam Basin is the Paleogene saline lacustrine source rocks. Traditionally, it was considered that these source rocks were characterized by low abundance and poor type of organic matter as well as limited oil generation ...

Environmental Evolution Recorded by Tamarix Nebkhas in the Qaidam Basin

Water
A typical Tamarix nebkha was studied in the southern Qaidam Basin, China. K-feldspar pIRIR dating was applied to establish a reliable chronological framework, and an Undatable age–depth model was constructed. Accumulation rates (AR) declined in stages: rapid (~1.33 cm/a; ~370–260 yr BP), slower (~0.75 cm/a; ~260–130 yr BP), and slowest (~0.31 cm/a ...

The relationship between groundwater and natural vegetation in Qaidam Basin

Journal of Groundwater Science and Engineering, 2021
To accurately evaluate ecological risks trigged by groundwater exploitation, it must be clarified the relationship between vegetation and groundwater. Based on remote sensing data sets MOD13Q1, groundwater table depth (WTD) and total dissolved solids (TDS), the relationship between groundwater and natural vegetation was analyzed statistically in the ...

Source and genesis of Ca-Cl type brines in Qaidam Basin, Qinghai-Tibetan Plateau: evidence from hydrochemistry as well as B and Li isotopes

Frontiers in Environmental Science
Ca-Cl brine is a highly mineralized special water body occurring in oceanic ridges or basins. The deep part of the western Qaidam Basin is rich in Ca-Cl brine, which is essential for the formation of (MgSO4-deficient) potash deposits. Previous studies on

Spatial Downscaling of Satellite-Based Precipitation Data over the Qaidam Basin, China

Remote Sensing
High-spatiotemporal-resolution precipitation data are essential for studies on regional hydrology, meteorology, and ecological conservation. Because the Qaidam Basin is a data-scarce region with a few ground stations and coarse-resolution remote sensing ...
