摘　　要：基于对胶东、晋北寒武纪变质岩系、超基性岩、基性岩、花岗岩类、火山岩类、硅铁建造铁矿、金矿蚀变带内 1 1个不同地质产状的 34个角闪石、 2 51个绿泥石、 60个黑云母单矿物的提纯 ,矿物的共生组合、物理性质、化学成分、X光衍射分析、热分析、红外吸收光谱分析、双矿物地质温度计、矿物压力计的测定 ,提出了角闪石、绿泥石、黑云母矿物成因族的地壳物质演化、成岩成矿作用、变质岩原岩恢复、地层对比、变质相、蚀变带的演化规律和地质找矿信息。Physical tests, such as X ray diffraction, thermal analysis, infrared absorption, measurements on pair mineral of geological thermometer and geological barometer mineral and chemical analysis on 34 amphibole, 251 chlorite;60 biotite samples of mono mineral and mineral assemblies from 11 different sites in Cambrian BIF iron ore deposits, metamorphic rock series,ultra basic, basic rock, granite and volcanics show an evolutionary pattern of amphibole chlorite biotite of genetic hierarchy.Data obtained can provide information of crust source, ore forming and rock forming processes,reconstruction of metamorphic rocks,stratigraphic correlation,rock facies,evolutionary pattern of alteration zonation and ore prospecting.
