摘要
某隆起区金矿床、矿点主要位于结晶基底杂岩中,主要成矿温度为中温—中高温热液成矿,成矿压力为中等,是在碱性、还原条件下形成的,金矿成矿热液来源与岩浆热液有关,并受到变质水的影响;成矿物质来源于上地幔、下地壳的深源物质,金矿主要形成于燕山期。
The gold-bearing deposits in some upswelling area occur in crystalline basement complex rock.Ore-forming temperature is from medium temperature to medium-high temperature.Metallogenic pressure is medium and the deposit is formed in alkaline and reduction circumstance.Gold metallogenic hydrothermal solution is related to magmatic hydrothermal solution and affected by metamorphic water.Metallogenic material comes from deep materials of upper mantle and lower crust.This deposit is formed during late Yanshanian period.
