    Abstract
  • Rock samples from 3 typical Lower Cambrian outcrops in the Upper Yangtze have been collected to test the content of total organic carbon (TOC) as well as major elements and trace elements. The characteristics of primary productivity and redox in the Early Cambrian, and their effect on organic enrichment were analyzed. In stages Ⅰ-Ⅱ, the shallow shelf was anoxic and ferruginous with a high primary productivity; the deep shelf was anoxic and sulphate rich with a low primary productivity; and the slope-basin where upwelling brought massive nutrients was anoxic and ferruginous with an extremely high primary productivity. In stage Ⅲ, the shelf was changed to oxic communicating well with the open sea and decreasing the preservation of organic matter. Although the slope-basin became oxic-suboxic in this stage, the primary productivity was high enough to prevent organic matter from complete aerobic degradation before it was buried. In general, organic-rich shale in the shelf which was deposited in a reducing environment was controlled by in the Eh at the bottom; organic-rich shale in slope-basin with a higher TOC content was controlled by primary productivity as well as the sedimentary environment. Organic-rich shale of the Lower Cambrian deposited on the shelf and in the slope-deep basin would be a target layer for shale gas exploration and exploitation.
