| 摘 要： | 西天山金属矿产十分丰富，是我国重要的Ｃｕ、Ａｕ 等多金属成矿带。金属矿床的形成及其成矿特点与大地构造背景密切相关。在拉张大地构造背景下主要形成与中基性和中酸性火山岩有关的Ｃｕ、Ｆｅ、Ａｕ 等矿床，次为与中酸性侵入岩有关的Ｃｕ、Ｍｏ、Ｗ、ＰｂＺｎ 等矿床及与基性、超基性侵入岩有关的ＣｕＮｉ 矿床。在挤压大地构造背景下，主要形成与重熔型花岗岩有关的斑岩型、矽卡岩型和热液型Ｃｕ矿、Ａｕ 矿等，次为沉积改造型ＰｂＺｎ 矿和Ｃｕ 矿床。文中还讨论了大地构造演化的不同时期金属矿床形成的主要特点，并据大地构造背景等成矿条件对西天山北部进行了找矿预测。

| Abstract: | Western Tianshan, which is very rich in mineral deposits, is one of the most important metallogenic belts of Cu, Au and other ore deoposits in China The formation and characteristics of mineral deposits are intimately associated with the tectonic settings Under extensional tectonic background, the major ore deposits formed are Cu, Fe, Au and other deposits in intermediate basic and intermediate acid volcanic rorks with minor Cu, Mo, W, Pb Zn deposits related to intermediate acid intrusives and Cu Ni deposits associated with basic and ultrabasic intrusives And in expressive tectonic environment, the predominant ore deposits are porphyry, skarn and hydrothermal Cu and Au deposits associated with remelted granites, and small amount of reformed sedimentary Pb Zn and Cu deposits Further more, the principal characteristics of ore deposits formed in different epoches of the tectonic evolution are discussed And based on such features as tectonic settings, the target for mineral exploration is put forward in the north of the western Tianshan |
