摘　　要：陕西西部、甘肃南部、四川东北部地区,是我国著名的的金成矿区。该区金矿类型多,砂金有冲积型和冰川堆积型,岩金有微细浸染型、含金石英脉型、构造蚀变岩型、多金属蚀变岩型、硒金型及火山岩型。根据区域地质构造单元划分及构造运动、岩浆活动、成矿规律及矿床地质特征,结合地球化学异常分布情况,该区初步划分为6个成矿带、3个成矿级别、7个成矿远景区。The area including west of Shanxi, south of Gansu, northeast of Sichuan is famous as ＂ gold triangle＂ of china. There is diverse gold styles, placer gold is possessed alluvial type and glacial stack type, rock gold is provided with micro-disseminate, gold-bearing quartz vein type, tectonic altered rock type, polymetallic altered rock type, seleniumgold and volcanic type. Based on partition of regional geological structural elements, tectonic activity, magma activity, metallogenic regularity and geological characteristics, combining with the distribution of geochemical anomaly,＂ gold triangle＂ can be divided into six gold metallogenic belts, three mining distinctions and seven metallogenic prospecting area.
