摘要:
文章综述了扬子陆块东南缘与华南裂谷系新元古代晚期地层划分研究取得的新进展。通过研究区域标志地层、沉积与沉积成矿事件并结合同位素测年资料,对争议较多的“板溪期”地层、南华系底界、南华冰期地层及武夷—云开一带元古宙构造、岩石、地层时代和层序进行了系统划分与对比,进一步厘清南华间冰期—冰后期大规模沉积成矿作用形成的铁、锰、磷、滑石及页岩气、黑色碳质页岩(石墨)等矿产成矿及生物大爆发事件链,探讨了区域地质构造、沉积与雪球事件等气候环境对沉积成矿规律的约束作用。
Abstract:
This paper summarized research progress on the late Neoproterozoic stratigraphic division between the western margin of the Yangtze block and the South China rift system. Based on regional index strata, sedimentary and sedimentary mineralization events, and isotopic dating data, previously controversial “Banxi stage” stratigraphy, bottom margin of the Nanhua System, stratigraphy of the Nanhua ice age, as well as the Proterozoic structure, rock, stratigraphic age and sequence along the Wuyi-Yunkai area were further compared and classified. Large-scale sedimentary mineralization during the interglacial and post glacial periods, which resulted in the formation of mineral deposits such as Fe, Mn, P, talc, and shale gas and black carbonaceous shale(graphite), was also determined. Constraint effect of regional geological structure, sedimentation and snowball events, as well as climate environment on the regularity of sedimentary mineralization was analyzed in this study.
