泌阳—确山一带萤石矿床特征成矿规律及靶区预测

Mineralization Characteristics and Target Area Prediction of Fluorite Deposits in Biyang-Queshan Area

通过地质资料收集、综合整理,开展泌阳—确山一带萤石矿床(点)调查评价、典型矿床特征研究等工作,重点研究与萤石矿有关的地层、构造、岩浆岩、区域地球化学特征以及区域矿产分布等成矿地质特征,总结研究区萤石矿控矿因素、成矿规律,进行了成矿预测;研究区萤石矿床主要为中低温热液充填型,矿床(体)主要受断裂构造及燕山期花岗岩体控制,赋存于北西—南东向主体断裂构造及次级断层中。以羊册—明港大断裂为主划分了3条成矿带、7个成矿远景区,圈定了3个找矿靶区,为今后该区萤石矿床的找矿勘查提供参考依据。

Through the collection and comprehensive collation of geological data,the survey and evaluation of fluorite deposits(spots)in Biyang Queshan area,the study of typical deposit characteristics were carried out,focusing on the study of the formation,structure,magmatic rock,regional geochemical characteristics,regional mineral distribution and other metallogenic geological characteristics related to fluorite ore,summarizing the ore controlling factors and metallogenic laws of fluorite ore in the study area,and carrying out metallogenic prediction;The main types of fluorite deposits in the research area are of medium to low temperature hydrothermal filling type.The deposits(bodies)are mainly controlled by fault structures and Yanshanian granite bodies,and occur in the main northwest southeast trending fault structures and their secondary faults.Based on the Yangce Minggang Fault,3 mineralization zones and 7 mineralization prospects have been divided,and 3 exploration targets have been delineated;This provides reference basis for exploration and development of fluorite deposits in the area in the future.
