现代定量矿产资源评价和现代成矿分析采用相似类比法,但也考虑其差异性。为了更好的理解这二种研究方法,本文比较对比了定量矿产资源评价和成矿分析两者间相似性和差异性,并应用于美国地质调查局的区域性、全国性和国际性项目研究中。作为对比研究的部分内容,文章阐述了两种研究方法,包括区域地质、地球化学、地球物理等基础图件,矿集区(成矿带)图的编制,以及矿床数据库、矿床模式的建立。文章同时阐述了如何综合合成矿床模式、构建基于高质量成矿分析的高质量定量矿产资源评价方法,以及与成矿构造模式关联。并以美国相邻区域为例介绍了现代定量矿产资源评价,以俄罗斯远东(Russian Far East),阿拉斯加(Alaska),及加拿大科迪勒拉(Canadian Cordillera)为例介绍现代成矿分析和成矿构造模式的关联。
Modern quantitative mineral resources assessment and modern mineral analysis using similar analogy, but also consider the differences. In order to better understand the two research methods, this paper compares the similarities and differences between quantitative mineral resources evaluation and metallogenic analysis and applies them to the regional, national and international projects of the US Geological Survey in. As part of the comparative study, the article describes two research methods, including the basic map of regional geology, geochemistry and geophysics, the drawing of the mineralized zone map, and the establishment of deposit database and deposit model. This article also elaborates how to synthesize the synthetic deposit model and construct a high quality quantitative mineral resource evaluation method based on high quality metallogenic analysis and to associate it with the metallogenic structural pattern. The area of the United States is used as an example to introduce the modern quantitative mineral resources assessment. The Russian Far East, Alaska, and Canadian Cordillera are used as examples to introduce modern mineralization analysis and mineralization Construct patterns of association.
