摘要
根据对东天山1500多处矿产地时空分布规律的初步研究,认为东天山具有矿产资源丰富、矿种多,铁铜镍煤盐等优势矿产比较明显、矿床类型较全、成矿历史悠久、空间分布相对集中且呈“南铁北铜东镍中间金”的特点。鉴于东天山地区基础地质工作程度偏低,科学研究深度不够,根据其地质演化规律和区域对比,认为东天山地区今后的找矿工作既要重视深入研究典型矿床,在查明矿床成因的基础上建立成因模式、找矿模型和综合评价模型,也要不同矿种之间、先后地质时代之间、相邻成矿区带之间相互借鉴,开拓思路,以期取得新进展。建议国家和相关产业部门以铁、铜为导向,集中目标开展找矿会战并带动其他矿种实现找矿新突破。
Study of the temporal-spatial distribution of more than 1500 mineral deposits in the East Tianshan, Xinjiang, shows that the East Tianshan is featured by rich mineral resources, a great variety of minerals （of which advantageous minerals such as iron, copper, nickel, coals and salts are more pronounced）, a relatively complete range of mineral deposit types, a long history of mineralization and relative clustering of different types of mineral deposit （e.g. iron deposits cluster in the south, copper deposits in the north, nickel deposits in the east and gold deposits in the central part of the East Tianshan）. In view of the low levels of fundamental geological work and scientific research, based on the geological evolution and regional correlation of the region, the following suggestions are presented： ① attention should be paid not only to studying typical deposits intensively and constructing the genetic model, prospecting model and comprehensive assessment model on the basis of ascertaining the geneses of the mineral deposits but also to comparing the metallogenic characteristics of different mineral deposits of different geologic ages in neighboring ore districts or belts to open up one＇s ideas in an attempt to make further progress in mineral prospecting; and ② the state and relevant industrial sectors should concentrate their efforts to carry out iron and cop- per prospecting, which will give an impetus to prospecting for other minerals and make a breakthrough.
