摘要 地洼学说对成矿学的贡献很多很大,现已发展成为国际性的大地构造成矿学派之一,地洼学说对成矿学最突击的贡献,是创造性地从地壳大地构造单元中划分出地洼成矿区,并与地槽区、地台区并列,成为一种新型的大地构造矿区。因而扩大了找矿领域,指明了研究的新动向,获得了显著的找矿效果;地洼学说对成矿学的又一突击贡献,是提出多因复成成矿论及多因复成矿床。陈国达教授的著名论文《从地壳演化规律看多因复成矿床及其形成机理》,指出这类矿床具有多成矿阶段、多物质来源、多成因类型、多成矿作用及多控矿因素的五多特点,是多阶段多期次成矿作用的综合结果。这一理论已广泛运用于成因有争议的矿床研究。解决了多年争论不休的学术问题,指明了新的找矿和研究方向。由于地洼学说在成矿学中的广泛运用,使地洼成矿区的时代,已从晚古生代和中、新生代,推延到元古代和早古生代,地洼成矿区的空间分布,由亚洲、欧洲、非洲,扩展到北美洲、南美洲和澳洲等世界各地。地洼学说使成矿学研究引向深入,有许多领域有待探索。 Diwa theory has made a lot of contribution to metallogeny and has developed into an international geotectonic-metallogenic theory. The most outstanding contribution of diwa theory to metallogeny is that a new metallogenic unit, diwa metallogenic regions, is carved up from crustal gcotectonic-metallogenic units. It is a new type of geotectonic—metallogenic region, being juxtaposed with geosynclinal and platform regions. Therefore it widens the field for ore exploration, points out a new way for studying metallogeny and achieves remarkable success. The another outstanding contribution of diwa theory to metallogeny is the concept of polygenetic metallogeny and polygenetic compound ore deposits. Professor Chen Guoda in his paper 《Polygcnetic Compound Ore Deposits and Their Orion in the Context of Regular- ities in Crustal Evolution》 pointed out that this type of deposits is characterized by 'five manys' : many metallogenic tectonics stages, many material sources, many ore-forming processes, many genetic types and many ore controls, and that it is the synthetical result of polystage metallogenesis. The theory has been applied to studying mineral depositswhose genesis is contentious, solved many academic problems which are debated endlessly over many years and pointed out new ways for ore exploration and study. As a result of the wide use of diwa theory, the age of diwa metallogenic regions is extended from the Late Palaeozoic, Mesozoic and Cenozoic in the past to the Proterozoic and Early Palaeozoic now, and their spatial distribution from Asia, Europe and Africa to North America, South America and Australia. Diwa theory has deepened metallogeny, and many fields remain to be probed. A grand goal and a concrete plan have been claborated. Ⅰ am sure that greater success may be scored in diwa thoery in future.
