西昆仑——阿尔金成矿带地层-岩石-构造时空格架及成矿地质背景新认识

New Understanding on the Time and Space Framework of Strata-Rock-Structure and the Metallogenic Geological Background of Metallogenic Belt in Western Kunlun-Arkin

西昆仑—阿尔金地区自然环境十分恶劣,交通特别困难。近年,地质找矿取得突破性进展,但成矿地质背景调查研究明显滞后,为提高西昆仑—阿尔金成矿带成矿地质背景研究程度,中国地质调查局及时跟进了区域地质调查和综合研究,项目实施以来取得诸多成果和认识,厘定并建立了成矿带地层、侵入岩、构造时空格架,特别对重要赋矿地质体和控矿构造开展了重点调查,研究了重要地质构造事件对成矿的控制作用。

The West Kunlun-Ahyn region features extremely bad natural environment and particularly poor transportation. In recent years, however, some breakthroughs have region, but its metallogenic geological setting investigation was obviou made in the geological explorations of the sly lagging. In order to improve the research level of metallogenic geological setting of the West Kunlun-Altyn metallogenic belt, the China Geological Survey deployed some regional geological survey projects and comprehensive research projects. These projects have got lots of achievements and progress： the spatio-temporal framework of strata, intrusive rocks and structures in the metallogenic belt has been established; significant ore-bearing geological bodies and ore-controlling structures have been surveyed; and the effects of important tectonic events on the mineralization have been studied.
