摘　　要：根据地质构造和矿产分布特征,将天山—北山成矿带划分为西南天山、东天山、西天山、北山4个单元。依据1∶20万水系沉积物测量数据,对比分析了主要成矿元素在整个成矿带及4个构造单元的背景值、元素的空间分布规律、元素富集特征及其与成矿的关系等。得出西南天山、西天山元素富集特征反映了以金为主的矿化特征;东天山反映以金、铜(镍)、银多金属为主的矿产格架,北山是以金为主矿化特征。According to geological structure and mineral distribution, the ore-forming belt of Tianshan-Beishan in Xinjiang is divided into southwest Tianshan mountain, east Tianshan mountain, west Tianshan mountain and north Tianshan Mountain. This paper systemically contrasts and analyses the background value and its distribution, the relationship between element enrichment and ore-foming of the four units. It is concluded that： the enrichment of main ore-forming elements in northwest and west Tianshan mountains represents the character of gold mineralization; east Tianshan mountain represents the mineral pattern of Au,Cu, （Ni）, and Ag; the north Tianshan mountain is dominated by the ore-forming character of gold.
