Abstract The black rock series in the Qiongzhusi Formation contains important geochemical information about the early Cambrian tectonic and ecological environment of the southwestern Yangtze Block. In this paper, major, trace, and rare earth element data are presented in an attempt to reveal the sediment source during the deposition of the early Cambrian Qiongzhusi Formation and to reconstruct the sedimentary tectonic environment and weathering intensity during that time. The basin primarily received continental clastic material with neutral-acidic igneous rocks from a stable source and with a moderate level of maturity during the depositional period of the Qiongzhusi Formation. Furthermore, the strata were weakly influenced by submarine hydrothermal fluids during diagenesis. The reconstruction of the sedimentary environment and weathering intensity shows that P2O5 enrichment and water body stratification occurred due to the effects of upwelling ocean currents during the depositional period of the Qiongzhusi Formation. The combination of upwelling and bottom-water hydrothermal fluids led to environmental changes in the study area, from dry and hot to moist and warm. Last, the reconstruction of the tectonic environment of the Qiongzhusi Formation indicates that deposition occurred in continental slope and marginal marine environments associated with a continental arc tectonic system. These findings provide an essential basis for the comprehensive reconstruction of the early Cambrian sedimentary environment of the Yangtze Block.

Black Rock Series

The North area of Yunnan Province is one of favorable target areas for prospecting shale gas of marine hydrocarbon reservoirs in South China, with the black rock series developed well at Lower Cambrian Niutitang Formation and Lower Silurain Longmaxi Formation. The black rock series can be classified into seven types of lithofacies，including black shale，siliceous shale， calcarleous shale，silty shale，carbonaceous shale，argillaceous siltstoue and carbonatite. The total content of organic carbon is 0.02% to 9.37%.The organic matter is overmature，with 2.05%～3.62% of Ro and dominated by type II-kerogen. The microporosity is dominated by the micropores，with pore size less than 10nm, secondly is foraminules with pore size ranging from 10nm to 100nm. The shale gas content is low overall，only 0.42 stere per ton average，and variety range is relatively large. Our research shows the content of plagioclase, carbonate and clay inflect the content of shale gas in the area of relieved synclines and less fault.
