甘肃西秦岭地区地球化学特征及找矿预测

利用西秦岭地区近20年来取得的数以万计的化探数据，借助计算机技术及GIS地理信息进行处理，重点选择主要成矿元素Au、Cu、Pb、Zn、W进行研究。从元素地球化学特征分析入手，研究元素在空间、时间上的迁移、富集、分散规律，通过对西秦岭地区成矿元素地球化学规律研究，提供了全面、详实、系统的地球化学成果，为区域矿床地球化学预测研究提供理论依据。提出了主要找矿远景区及找矿有利地段，为下一步矿产勘查工作提供靶区。

GEOCHEMICAL CHARACTERISTICS AND ORE-PROSPECTING PROGNOSISOF THE WEST QINLING AREA IN GANSU PROVINCE

Using more than ten thousand data collected in the past 20 years since the beginning of geochemical prospecting in the West Qinling area and adopting computer and GIS technology,the authors selected and studied five key ore forming elements of Au,Cu,Pb,Zn and W. Starting with geochemical features,the authors investigated their migration,enrichment and dispersion in time and space. Based on probing into their geochemical characteristics in such areas as Beishan, Qilian Mountains and West Qinling,the authors obtained complete,detailed and systematic geochemical outcomes, which provide theoretical basis for geochemical prognosis of regional ore deposits.The main prospective areas and favorable zones for exploration are pointed out,which is most helpful to further ore-prospecting work.
