摘要
新疆大地构造呈"五块夹四条"的格局,西伯利亚、哈萨克斯坦-准噶尔、塔里木-华北、华南、西藏5大板块,由查尔斯克-乔夏哈拉-布尔根、那拉提-红柳河、康西瓦-鲸鱼湖、阿克赛钦-金沙江4条缝合带隔开.各板块都经历了"陆核→陆块→陆缘→陆内发展"演化阶段.各演化阶段成矿作用不同,形成特色各异的矿产,其中"环塔里木"主要为"层控"有关的沉积变质型铁、热卤水型和碳酸盐岩型铅锌、砂岩型铜、破碎蚀变岩型和砂砾岩型金矿产等,"环准噶尔"主要为斑岩型、镁铁-超镁铁岩浆型、火山岩型铜钼、镍、铬、金等矿产.此外,还产有重要的稀有金属和稀土及石油、天然气、煤、铀、膨润土和膏盐类等非金属矿床.
Tectonics of Xinjiang shows＂five blocks and four belts＂pattern.Siberia,Kazakhstan-Junggar,Tarim-North China,South China and Tibet blocks was divided by four belts that is Charles-Qiaoxiahala-Buergen,Nalati–Hongliuhe,Kangxiwa-Jingyuhu,and Aksai Chin-Gold Sand River.The plates have experienced four evolution stages that include the continental nucleus,continental block,margins and intra-continental stage.As a result of different evolutionary stages of mineralization,it appears different mineral characteristics.For example,around Tarim basin mainly including strata-bound iron,lead,zinc,copper,gold deposits,around Junggar mainly include porphyry,mafic-ultramafic magmatic,volcanic rock-type copper-molybdenum,nickel,chromium,gold and other minerals.
