| 中文摘要:笔者等根据全球6大洲、121个国家(地区)、22个矿种、1285个矿床的储量数据,进行了储量量变线性回归方程趋势分析。根据回归方程不同系数切割的量变界线,划分出了36个特(超)大型矿床(顶峰矿)、95个超大型矿床和314个大型矿床。据此,笔者等创新地提出了按不同储量量级划分大型-超大型矿床的新认知,继而将3类不同量级的445个大型-超大型矿床投影在1:2500万全球构造背景图上,并划分出4大成矿域、21个巨型成矿带(区)。其全球成矿规律是:内生、外生、变质和后成矿床的全球成矿统一性;不同成矿区带成矿的专属性;Cu、Au、Fe、Ag、Cr、Mn、Zn、Pb、Sb、Hg不同成矿金属,大陆边缘和板块汇聚带以及陆内构造-岩浆杂岩带和大型剪切带的成矿偏在性;特(超)大型矿床太古代-古元古代全球氧大气变态(过氧事件)、元古代-古生代全球还原大气变态(缺氧事件)和中-新生代构造圈热侵蚀(巨量构造-岩浆事件)的成矿异常性。 |

| Abstract:Based on the database of 1285 mineral deposits constituting 22 commodities in 121 countries (areas) from 6 continents in the world, the authors used the linear trend analysis for their reserves to determine the cut-off limited order of reserves. As a result, 36 exceptional superlarge deposits (peak mineral deposits), 95 superlarge deposits and 314 large deposits were selected as new cognition for their quantitative change. The authors projected over 445 large-superlarge deposits on the (1:25 M) global tectonic background map and assigned them to 4 metallogenic domains and 21 metallogenic belts. Global metallogeny of large-superlarge deposits includes unity of endogenic, exogenic metamorphic and epigenetic ore-forming processes in origin; speciality of different metallogenic domains and belts; preferentiality of ore-forming elements of Cu, Au, Fe, Ag, Cr, Mn, Zn, Pb, Sb, Hg to continental margins or plate convergent belts, intra-continental tectono-magmatic complex belts and large ductile shear zones; abnormality of the global oxyatmversion (oxygen-excessing atmospheric event) in Archean-early Proterozoic, redoxyatmversion (oxygen- lacking atmospheric event) in Proterozoic-Paleozoic, and tectonosphere thermal erosion (great amounts of tectonic magmatic event) in Mesozoic-Cenozoic. |
