成矿作用爆发异常及巨量金属堆积

在对华北地台北缘和南岭两金属成矿省代表性矿田的等级体制成矿研究的基础上，应用矿床储量相对丰度及其形成时限推论巨量金属堆积速率，探讨了大气变态和构造圈热侵蚀等成矿热事件在地质历史上出现频率及其激发巨量金属堆积的成矿规律，为爆发异常成矿提出新思路，据此，提出鞍（山）－本（溪）铁建造成矿区的成矿远景还将有扩大的可能，湘桂粤拗陷和粤北隆起两成矿区的钨锡成矿远景也将有望再扩大。

The explosive anomaly of ore-forming processes and superaccumulation of metals

Based on the research of hierarchical systematic metallogeny in the typical ore fields along the northern margin of Sino-Korea platform metallogenic province and Nanling metallogenic province and applying superaccumulation rate of metals deduced from the relative abundances and metallogenic intervals of ore deposits, the authors probe into the emergence frequency of such metallogenic thermal events as atmosphere metamorphosis and tectonosphere thermal erosion that aroused superaccumulation of metals and present a new idea of explosive anomaly of ore-forming process. Furthermore, the minerogenic prospects of BIF are expected to enlarge in Anshan-Benxi area of North China, and the minerogenic prospects of tungsten and tin deposits in Hunan_Guangxi_Guangdong depression and Northern Guangdong uplift are also promising.
