Abstract

Abstract

The source of the organic matter in the metallic deposit is one of the important and difficult issues for the research into the biological mineralization. Relatively great differences, especially in terms of organic group constituents, w(C₂₃)/w(C₂₁) ratios of tricyclicterpanes, w(Ts)/w(Tm) ratios of triterpene, w(γ-cerotene)/w(C₃₁αβS-hopane) ratios, and steranes series, are present between the organic matter in the metallogenic fluid in the Qixiashan polymetallic deposit, Nanjing occurring in the Carboniferous dolomites, and that, present as marine petroleum, adsorbed in the Upper and Lower Paleozoic hydrocarbon source rocks in the lower Yangtze region. However, the organic matter in the fluid is similar in several aspects to the enclosed organic matter in the Cambrian carbonate rocks (i.e., one of the mineral source strata), since the two kinds of organic matters are related to each other in their origin.
- metallic deposit,
- organic matter of oreforming fluid,
- enclosed organic matter,
- biological marker compound,
- Nanjing
