- 《Norwegian Journal of Geology》 被引量: 22发表: 2010年 Magnetic and gravity modelling of the crystalline basement in the North German Basin The knowledge about the surface of the crystalline basement in the North German Basin is of special interest for the exploration of the tectonic-...
Because most of the Permian basin region of west Texas and southern New Mexico is covered by Phanerozoic rocks, other means must be found to examine the Precambrian upper crustal geology of the region. We have combined geologic information on the Precambrian from outcrops and wells with geophysica...

In general, all studies agree that the geological framework and structural characteristics are complex, thereby masking a comprehensive understanding of the regional geology and hydrocarbon occurrences. The Junggar Basin is an important petroliferous basin in China. The research and exploration history (...

Here, we report the detailed geology and geochemistry of siliceous rocks from three well-preserved Da-long Formation deep-water sections that have recently been discovered in the Lower Yangtze region, and discuss the genesis of the Da-long cherts and ocean chemical conditions during the late Permi...
