本文分别总结了巨大区域图(<1:1千万)、区域图(1:1千万—1:25万)、地区图(1:6万—1:2万)、矿化点图(1:6千—1:1.2千)的沉积主岩和火山主岩两种不同主岩中浸染型金矿床的找矿判据。巨大区域范围内浸染型金矿床的找矿判据主要为各种勾通深源的构造及有利的基底;区域性范围内的找矿判据主要为:存在大型线性构造、有利的岩浆组合和地球物理特征;地区性范围内的找矿判据主要为:存在有利的地层、成矿空间、热改造条件及有利地球物理、地球化学特征;矿化点范围的找矿判据主要为:存在似碧玉岩或玉髓质脉及硅华、有利的蚀变矿物组合、控矿构造及微观地球化学特征。
In this paper, we summarize the results of huge regional maps (<1: 10 million), regional maps (1: 10-150,000), regional maps (1: 60,000-1: 20,000) 1: 6-1: 1.2) sedimentary host rocks and volcanic host rocks in two different host rocks disseminated gold deposit prospecting criteria. The prospecting criteria of disseminated gold deposits in a huge area mainly include various deep-sourced structures and favorable substrates; the main ore-prospecting criteria in the area are: large linear structures, favorable magmatism assemblages and earth The main ore prospecting criteria in the region are: there are favorable strata, metallogenic space, thermal transformation conditions and favorable geophysical and geochemical characteristics; the ore prospecting criteria in the range of mineralization are mainly as follows: Jasper or chalcedony veins and silicon, favorable alteration mineral assemblages, ore-controlling structures and microscopic geochemical characteristics.
