内蒙古千里山铁矿成矿地质特征及矿物学研究
Study on Ore-forming Geological Characteristics and Mineralogy of Qianlishan Iron Deposit in Inner Mongolia
摘要
Abstract
In this paper,geological characteristics of Qianlishan study area located within early Proterozoic Khondalite Belt in the western block of the North China Craton have been studied.Qianlishan iron deposit is located in Wuhai city in Inner Mongolia with complex geological structures.Through analyzing petro-graphic characteristics in this area,diopside-mica-scapolite schist,hornblende Monzonite gneiss and di-opside-biotite-scapolite-hornblende schist have been identified.According to electron probe microanaly-sis(EPMA)results,it is indicated that Qianlishan hornblende is mostly of high-grade metamorphic ori-gin.It has reflected the characteristics of ancient basement and abundant metamorphic rock.The biotite is mantle-derived,and near the crust mantle mixed source.It is favorable for mineralization of Au,Mo,Cu,and Fe.The chemical composition of pyroxene shows that the parent magma belongs to the tholeiitic series,characterized by high SiO2,low TiO2,Al2O3 and Na2 O.In addition,high crystallization tempera-tures of pyroxene and biotite in Qianli Mountain area indicate high-temperature characteristics of parent magma.High oxygen fugacity biotite may indicate good mineralization potential for Fe,Cu,and Au.This study provides important clues for mineral exploration.关键词
