摘要:
提要:近年来,蒙古戈壁天山和中国北山—天山地区均发现重要斑岩型铜(金钼)矿床,但这些斑岩型矿床是否属于同一条斑岩成矿带一直没有明确的结论。本文通过对戈壁天山、北山、天山典型斑岩矿床地质特征和成岩成矿年龄学资料的分析和总结,发现这些地区的斑岩型矿床均主要形成于泥盆-石炭纪岛弧背景之下,并且大多数矿床与埃达克岩有关。因此,提出它们应属于同一斑岩成矿带,与世界新生代巨型斑岩成矿带形成背景相似,暗示中亚造山带具有重大的资源潜力。

Abstract:
Abstract: In recent years, many porphyry-type Cu deposits have been found in Mongolian Gobi-Tianshan and in Chinese Beishan and Tianshan. This paper summarizes geological characteristics and metallogenic age data of typical porphyry-type deposits in these areas and suggests that the deposits were mainly formed during Devonian-Carboniferous. Meanwhile, most of these deposits are genetically related to adakites, indicating that they were formed in a volcanic arc setting. It is held that the deposits in these areas likely constitute a single giant porphyry-type metallogenic belt, which straddles the border between China and Mongolia. The features are analogous to features of the porphyry deposits in Neocene, implying great resource potential of CAOB (Central Asian Orogenic Belt).
