Surface pollen in the east of Qaidam Basin

Journal of Geographical Sciences, 2006
Pollen analysis of 23 surface samples in the east of Qaidam Basin reveals the characteristics of pollen assemblages and their relationships with vegetation and climate. In pollen assemblages, Chenopodiaceae and Artemisia are preponderant types in all the samples, and Ephedra, Gramineae and Compositae are common types.

Biogenic gas systems in eastern Qaidam Basin

Marine and Petroleum Geology, 2008
Abstract Several giant biogenic gas fields (with proven gas reserves greater than 25 billion cubic meters) have been discovered in recent years in the Sanhu area of eastern Qaidam Basin. This area has an average surface altitude of around 2800 m, and forms the northern segment of the Qinghai-Tibet Plateau.

Late Accumulation of Kunbei Area in Qaidam Basin

Advanced Materials Research, 2013
This paper is aimed to find out the main reason of late accumulation of Kunbei area in Qaidam Basin using geochemistry and seismic data and to provide scientific evidence to the potential petroleum exploration in this area. Reservoirs in Kunbei fault terrace zone originate from petreoleum generated by source rocks of E32 in Zhahaquan depression after ...

The Evolution of the Quaternary Salt Lakes in the Qaidam Basin

Acta Geologica Sinica - English Edition, 1994
Abstract The paper discusses the distribution of Quaternary sediments, occurrence of saline minerals and phases of neotectonic movements and their manifestations in the Qaidam basin. The formation of four successive lacustrine terraces in Tertiary anticlinal zones in the western part of the basin was related to the neotectonic movements that took place

Hydrogeological prospecting in the Da Qaidam area of the Qaidam Basin using the audio-frequency magnetotelluric method

Journal of Applied Geophysics, 2020
Abstract The Qaidam Basin has very little precipitation but large surface evaporation. Besides, the groundwater resources are unevenly distributed, which gradually decrease from east to west. Therefore, reasonable exploration and management of the groundwater resources are very important in this area.

Yardang geometries in the Qaidam Basin and their controlling factors

Geomorphology, 2017
Abstract The hyperarid Qaidam Basin features extensive fields of yardangs (covering an area of ~ 40,000km2) sculpted in tectonically folded sedimentary rocks. We extracted the geometries of 16,749 yardangs, such as length-to-width ratio (L/W), spatial density, and spacing, from multi-source remote sensing data provided by Google Earth™. We classified
