广西丹池锡多金属成矿带的带状分布及演化模型

摘要：详细论述了丹池地区热变质岩、矿床类型、矿物组合及相应的硫、铅、碳、氧、氢稳定同位素和成矿物理化学环境的分带性和演化特征，指出矿带的形成在时间和成因上与燕山晚期地壳重熔型含锡花岗岩有着密切的关系，它们共同构成了该区构造一岩浆成矿演化的统一整体，建立了丹池锡多金属成矿带的分带演化模型。

ZONALITY AND EVOLUTION MODELS OF DANCHI TIN-POLYMETALLIC ORE BELT, GUANGXI ZHUANG AUTONOMOUS REGION, CHINA

The authors give out more detail results of the study in Danchi tin-polymetallic ore belt, including those on thermal metamorphic rock, types of mineral deposits, mineral assemblage, stable isotope of sulphur, lead, carbon, oxygen and hydrogen and mineralization zonality as well as physical chemistry evolution feature of the ore belt. The authors draw a conclusion that there is a very close time-space-metallogeny tie between the ore belt and the tin-bearing granite of crust remelting type, which formed in the late Yanshan Movement, and they constitute an evolution entity of tectono-magma mineralization. Zonality evolution models are subsequently established here.
