The system consists of the following procedure: pre-concentration of metallogenic matter in living organisms in primary depositional basin; solution, absorption and concentration of metallogenic matter in organic matter and organic thermal fluid generated from organisms during lithogenesis; migration of metallogenic matter in organic thermal fluid from basin to mountain region and activation of metallogenic elements by organic matter and organic thermal fluids in sedimentary strata in mountain regions during basin compaction and mountain building; metallization due to reactions between inorganic fluid and organic fluid bearing metallogenic matter and because of reductions and absorptions by organic matter in mountain regions.

生物成矿系统的内容是：在原始盆地接受沉积时，生物对金属成矿物质就存在预富集作用；在成岩过程中，生物转化为有机质及有机热流体，对金属成矿物质存在溶解、萃取、富集作用；在盆地压实和造山活动中，盆地中有机热流体向造山带运移，此过程流体携带大量成矿物质，对金属成矿物质存在迁移作用，而处于造山带沉积地层中的有机物及有机流体对金属成矿元素存在活化作用；盆地有机热流体与造山带含金属流体会合，以及造山带有机质及有机流体对金属元素进行还原和吸咐，最终形成金属矿床，对金属成矿物质存在成矿作用。

Because of the impact of precipitation facies and lithogeny, there are many complex reservoirs in Nanpu oil field with characteristics of high bond water saturation, high cation exchange capacity and complex pore structures. The reservoir's electrical parameters are different from that of conventional sandstone reservoir so that we can't use Archie's equation to do reservoir evaluation.

The ore-bearing fluid of the Dabaoshan deposit is related to magmatic thermal dynamic process, and volcanogene hydrothermal sedimentary polymetallic deposit on seabed was formed. The Fankou Ore-bearing fluid is related to circulation hydrothermal in deep formation, and middle-lower temperature Pb-Zn-Ag-Hg polymetallic sedimentary deposit by sea-floor thermal spring and overflowing was formed. The Hongyan ore-bearing fluid is related to the compaction water that formed by the basin's lithogeny process, and low temperature and pyrite only was formed.
