现代成矿理论的某些进展

NEW THEORIES AND ADVANCES OF CONTEM-PORARY METALLOGENESIS

本文简要分析了成矿理论的发展趋势，重点对１０种现代成矿理论作了简要的介绍，它们是：同生成矿理论、浅生成矿理论、微生物成矿理论、边缘成矿理论、纬度分带成矿学说、软硬酸碱成矿理论、建造分析成矿理论、浅成低温热液贵金属成矿理论、成岩作用促使沉积成矿理论和砂金成矿的细菌结晶机制。笔者认为成矿理论的研究应注意综合性、多因素和适用性，还强调成矿理论随着地质科学不断发展而逐步丰富和完善。

This essay briefly evaluates the development tendency of metallogenetic theoriesand gives a brief introduction to 10 types of contemporary metallogenetic theories. Theyare theories of syngenetic metallogenesis,supergene metallogenesis,microbiogenic metal-logenesis,marginal metallogenesis,latitudinal zoning metallogenesis hypothesis,softand/or hard acid-alkali metallogenesis,formation analysis metallogenesis,supergene hy-drothermal precious metal metallogenesis,petrogenetic metallogenesis and bacterial crys-talization mechanism in sandstone gold deposits. It is believed that comprehension,poly-factors and suitah11ty are important in the studies of metallogenetic theories and that themetallogenetic theories will be perfected gradually with the progress of earth sciences.
