The Development of Sedimentary Buildups and Mineralization in the Eastern Qinling Mountain |
According to tectonic characteristics of the study area on the southern margin of North China paleocontinent, the geotec-tonic framework of the area could be divided into five units:(1)the Huashan-Xong'er Mountains continental margin belt;(2)the Kuan-ping Late Proterozoic accretion belt of the paleocontinent;(3)the Erlangping margin basin zone;(4)the Qinling dispersion type island arc terrain; (5)the sedimentary basins of Nanqinling zone. In the light of the evolutionary stages of the sedimentary formation as well as metallogenesis, it can be classified into:(1)the sedimentary formation in the active southern margin of the pre-Mesoproterozoic North China Paleocontinent;(2)the sedimentary formation in the Middle-Late Proterozoic inactive continent margin; (3)the sedimentary formation in the early Paleozoic converse type continent margin;(4)the sedimentary formation in the Paleozoic active margin;(5)the phase of Mesozoic collision. |
