出发点金属矿产的分布有明显的地区性,不同地区出现的矿产往往截然不同.认识这一规律性有助于正确布置找矿工作,很有意义. 不同矿产的分区出现,在以前,常用地槽或地台发展的特定阶段的产物来解释.近年来,又常把它看作板块发展的特定阶段的产物和以距毕乌夫带的远近来进行解释.但我国东部燕山期的成矿作用却显示了一系列复杂的情况.例如,原桂林冶金地质研究所有关研究组(1975、1976)曾指出过如下基本事实:
The starting point of the distribution of metal minerals have obvious regional, different regions appear often different minerals .A understanding of this regularity is conducive to the correct layout of the prospecting work, it makes sense .Different minerals appear, in the past, Or the stage of the development of platform to explain the product.In recent years, it is often seen as a plate of the specific stage of product development and the distance from the Bieuofu to explain, but the mineralization in eastern Yanshanian But shows a series of complex situations.For example, the former Guilin Institute of Metallurgy and Geology related research group (1975,1976) pointed out the following basic facts:
