| 摘 要： | 从金砂矿区全球分布图与原生金矿富集区分布图对比分析中,得出中-大型金砂矿物质应来源于原生金富集区金矿床的结论。据此分析了四川大型金砂矿多集中于第四纪,并分布在相对很狭窄的樟腊-平武、古城-白水一带,指出龙门山海西-印支褶皱带东北段与西秦岭褶皱带交汇地区,可能存在着提供大型金砂矿物质来源的原生金矿富集区.

| Abstract: | The author makcs a correlation between thc distribution diagrams of placer gold ore deposits in the world by R.W. boyle and the distribution diagrams of the arcas rich in primary gold ore deposits presented by the author himself and reaches a conclusion that the source of middle-large-scale placer gold mincrals should be the primary gold ores. Based on this, the author considers that the largescale placer gold ore deposits in Sichuan province are mainle in the narrow zone of Zhangla-Pingwu and Gucheng Beishui, showing that there may have existed a district rich in thick gold ore deposits which had provided many matcirals of large-scale plarce gold orc deposits in an intersection arca between Northeast section of Longmen mountain Hercynian-Indosinian fold belt and Western Qinling fold belt. The author also suggests a future prospecting and exploring program. |
