摘要
滇东南锡多金属矿产围绕花岗岩成矿中心在某一或某几个特定的象限内作带状分布,各个成矿中心在区域上等间距出现,成岩成矿主要在燕山期,与早期岩体有关的矿产主要伴生金,与晚期岩体有关的矿产主要伴生银,不同成分的花岗岩有不同的矿产分布形式.
In southeastern Yunnan Province Sn-bearing multimetallic ore deposits always distributd surroundinga granitic massas a metallizing centre and zonally scatter in a given quadrant or two. Regionally metallizingcentres are appeared in equal distance. Diagenesis and mineralization are chiefly of the YanshanianPeriod. Gold and silver are mainly associated with mineral products related to the rock mass of theearly and late periods respectively. Granitic masses of different compositions have different mineralproduct distribution patterns.
