摘要
贵州境内的玄武岩可分为钙性区、钙碱性区及碱钙性区,其碱钙性区碱度高,并与贵州西南部一系列金矿床(点)有一定成因联系,碱钙性玄武岩分布区及其东部大片火山碎屑—热水沉积区是新的金矿远景区。
Guizhou cisborder basalt can be mainly divided into caleic basalt area, calc - alkaline basalt area and alkali - calcic basalt area. The alkalinity is high in area of alkali - calcic basalt, and in southwest of Guizhou a series of gold deposits （points） have a genetic connection with alkali- calcic basalt. The distributing area of alkali - calcic basalt and its eastern pyroclast - hydrothermal sedimentation is new prospecting potential gold- deposit locations.
