秦岭造山带经过多期构造活动、壳一幔物质交换、地质流体和成矿物质汇聚集，使其成为我国重要的金属矿产资源基地之一。目前秦岭造山带（陕西）地质找矿存在若干问题。本文从矿产的分布、地球化学、板块构造成矿理论等，对铜、钼、铁、金、银、铅、锌、钨、锡、汞、锑等元素的成矿进行了分析研究，从而探讨秦岭造山带（陕西）矿产中某些矿种为优势矿种，某些矿种为劣势矿种的原因。从金属来源和元素的浓集系数分析，秦岭整个区域都是寻找金、银、钼、铅、锌矿最有潜力的地区；从金属来源、元素的浓集系数及板块构造成矿理论分析，秦岭寻找具有较大规模的铜、铁族元素矿产仅限制在部分地区，即主要为两条缝合带靠近活动大陆一侧的边缘构造——岩浆活动带的基性度较高的勉略宁和北秦岭地区，其次是紫阳一镇坪地区；汞锑元素成矿必须具有很特殊的成矿地质物化条件。
秦嶺造山帶經過多期構造活動、殼一幔物質交換、地質流體和成礦物質彙聚集，使其成為我國重要的金屬礦產資源基地之一。目前秦嶺造山帶（陝西）地質找礦存在若榦問題。本文從礦產的分佈、地毬化學、闆塊構造成礦理論等，對銅、鉬、鐵、金、銀、鉛、鋅、鎢、錫、汞、銻等元素的成礦進行瞭分析研究，從而探討秦嶺造山帶（陝西）礦產中某些礦種為優勢礦種，某些礦種為劣勢礦種的原因。從金屬來源和元素的濃集繫數分析，秦嶺整箇區域都是尋找金、銀、鉬、鉛、鋅礦最有潛力的地區；從金屬來源、元素的濃集繫數及闆塊構造成礦理論分析，秦嶺尋找具有較大規模的銅、鐵族元素礦產僅限製在部分地區，即主要為兩條縫閤帶靠近活動大陸一側的邊緣構造——巖漿活動帶的基性度較高的勉略寧和北秦嶺地區，其次是紫暘一鎮坪地區；汞銻元素成礦必鬚具有很特殊的成礦地質物化條件。

After several multi-stage tectonic movements, crust-mantle material exchange, geology fluid and ore-forming materials together, Qinling orogenic belt has become a major base metal mineral resource. Currently geological prospecting in qinling orogenic belt （Shaanxi） exist a number of problems. In this paper, mineral distribution, geochemistry, plate tectonics theory ore, copper, molybdenum, iron, gold, silver, lead, zinc, tungsten, tin, mercury, antimony and other elements of mineralization were analyzed to explore the reasons why some are advantage minerals, and some are disadvantage minerals in the qinling orogenic belt （Shaanxi） minerals, analysis from source of metal and concentration factor of the elements, the entire region are the most promising areas as looking for Qinling gold, sil- ver, molybdenum, lead, zinc, tungsten, tin. From the metal source, the element concentra- tion factor and plate tectonics to mine theoretical analysis, looking for a large-scale Qinling copper, iron group elements is limited in parts of the montain, which is primarily {or the two active continental side of the suture zone near the edge of tectonic-rajah lye ning and slightly north Qinling region with a high degree of magmatic activity, after that is Ziyang-Zhenping areas. Mercury and Sb mineralization must have very special geological conditions.
