| 摘 要： | 通过野马泉地区1:5万地质矿产调查工作,发现野马泉地区A型正长花岗岩与矽卡岩型铁、多金属矿产关系密切,文中试图通过对正长花岗岩的岩石学、岩石化学、地球化学特征的研究和分析,在讨论正长花岗岩的成因基础上,通过同位素年代学研究,为确定野马泉地区与正长花岗岩有关的矽卡岩型矿床成矿时代提供依据。

| Abstract: | A close relationship between A type normal granite in Yemaquan area and skarn type iron and polymetallic deposit is found through the investigation if 1∶50 000 geology and deposit in Yemaquan area.Through the analysis of normal granite on the characteristics in petrology,pertochemistry and geochemistry,the ore-forming epoch on the skarn type deposit in Yemaquan area is determined on the basis of normal granite genesis and isotope chronology study. |
