查询词典 lithogenesis

The theories of mineralization system, geochemistry, submarine hydrothermal fluids eruption deposit lithogenesis and mineralization were used to study the characters of geology and typical deposits of Erlangping Group in East Qinling Orogenic Belt and the raltion between them was dicussed in the thesis.

运用成矿系统、造山带地球化学和海底热液喷流沉积成岩成矿等理论方法，对东秦岭二郎坪群地质特征和典型矿床进行了研究，进而探讨了二者之间的关系。

Mutual dissolution of water vapor and methane in the ancient HTHP situation and the formation of bound water in reservoir bed compaction lithogenesis led to the absence of water layers in deep basin gas accumulation.

深盆气形成于高温高压的环境中，早期地层水因汽化而与甲烷气混溶，一部分随岩性变致密加厚水膜而成为束缚水，导致深盆气盆地内无水层。

OR＞1 indicates dangerous factor, OR＜1 protective factor, and OR=1 no significance. The results showed that if triglyceride and very low density lipoprotein cholesterol increased an average level of normal respectively, and there would be OR of TG 2.43 (P＜0.05) and OR of VLDL-C 6.09 (P＜0.05), the high levels of TG and VLDL-C were the factors of lithogenesis. High density lipoprotein cholesterols (HDL1-C, HDL2-C, HDL3-C), with OR less than one, were the factors of protecting against the formation of gallstone.

结果：甘油三酯和极低密度脂蛋白胆固醇每增加一个正常均值水平，OR值分别是2.43(P＜0.05)和6.09(P＜0.05)，是重要的致石因素指标；高密度脂蛋白胆固醇(HDL1-C、HDL2-C、HDL3-C)，OR值均低于1，是重要的防石因素指标；低密度脂蛋白胆固醇和总胆固醇的OR值均小于1，本研究结果提示其可能是一种代谢状态而非保护因素。

The paragenetic relationship of hydrothermal sedimentogenic cherts and copper polymetallic deposits manifest that the copper polymetallic deposits are formed by the submarine hydrothermal exhalative lithogenesis and mineralization.

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。

The biometallogenesis system of Jinya gold deposits consists of the following procedure: pre-concentration of gold and metallogenic matter in living organisms in Luodian-Danchi rift depositional basin; solution, absorption and concentration of metallogenic matter in organic matter and organic thermal fluid generated from organisms during lithogenesis; migration of gold and metallogenic matter in organic fluid from basin to Lingyun underwater carbonate platform and concentration at its boundary convex (palaeo-blind-mountain) during basin compaction ; metallization due to depth thermal fluid making organic fluid thermal degradation and forming new fluid which riches in gold and sulfur, and the fluid migrating upward and depositing in upside ore-controlling structures because of absorptions by organic carbon and atc.

通过研究金牙金矿作用的生物成矿系统内容为：在早、中三叠世罗甸—丹池裂谷盆地接受沉积时，生物对金等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，对生物及沉积物中的金等成矿物质存在溶解、萃取、富集作用；在盆地压实成岩作用中，盆地中有机热流体向凌云水下碳酸盐台地运移，并在台地边缘外凸部位集中，此过程流体携带大量成矿物质，对金等成矿物质存在迁移集中作用；深部热流上侵使有机流体发生降解和释放金的热作用、形成高含金的有机热液，含金热液上移在构造通道中沉积并被有机碳再次吸附，最终形成金矿床，对金存在成矿作用。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
