中国金矿床(点)等密度图与成矿远景预测

ISOPYCNAL MAP OF CHINESE GOLD DEP0SITS (OCCURRENCES) AND PREDICATION OF METALLOGENETIC PROSPECT

根据中国政区内已获得的1500多个金矿床（点）位置。数量、矿量等参数编制单变量及矿化综合信息等密度图．目的在于以金矿量在中国区域地理分布的事实，暂时放弃难予定论的各学派在成矿区带研究上的不同观点，以矿床（点）密集区的客观实际所反映“矿源质”存在的自然趋向，作为成矿背景和控矿场的宏观到中观预测基础，提出等密度图预测标志、预测准则及预测结果．

Such parameters as locality, number and reserve of over 1 500 gold deposits or occurrences within the Chinese administrative territory, have been employed to compile an isopycnal map with a single variable and comprehensive mineralization information. The purpose of this research is to use the naturaltendency of the 'bioplasm of mineral sources' objectively reflected in the concentrated areas of the gold deposits (occurrences) as a solid foundation for the macro-and medium-forecasting of the metallogenic background and ore-control field, since different points of view of the research into the metallogenic belts are hard to be compatible with the actual geqraphic distribution of the gold deposits within the Chinase administrative territory and therefore should be temporarily put aside. In this case, the authors propose the forecasting indicators, forecasting criteria, and forecasting results of the isopycnal map.
