The continent of China developed through the coalescence of three major cratons(North China, Tarim and Yangtze) and continental micro-blocks through the processes of oceanic crust disappearance and acceretionary-collision of continental crusts. The strata of the Chinese continental landmass are subdivided into 12 tectonic-strata regions. Based on the composition of geological features among the three main cratons, continental micro-blocks and other major global cratons, their affinities can be p... 相似文献
<正>Objective The Zhongchaye vermiculite deposit is located north of Laiwu. Tectonically, it belongs to the Luxi Block, west of the Tan-Lu fault zone (Fig. 1a). The crystalline basement of this area consists of the Neoarchean Taishan Group and Paleoproterozoic Granitoid. The overlying strata are mainly Paleozoic carbonate rocks, Mesozoic clastic rocks, 相似文献
<正>Objective Deep-water deposit has become one of the greatest potential and economic areas for petroleum exploration. In the western Qaidam Basin, the deep-water sedimentary area account for nearly 2/3 of the basin area, but the related reports is less. Scholars generally believed that the salt water medium can inhibit the extension of the sand(Qian et al., 1984). 相似文献
