| 摘 要： | 东川脉状富铜矿在历史上对矿山、对国家曾作出过重大贡献。汤丹厚大的层状铜矿也是５０年代在广泛调查汤丹脉状矿的基础上发现的，从而肯定整个东川矿区层状矿的巨大工业价值。对脉状铜矿的成因，长期以来受着“脉状铜矿由层状铜矿就地取材”转化形成的思想束缚，因而对其评价－研究成果甚少。从脉矿现有的历史资料出发，结合当今的研究成果，认为东川矿区广泛分布含铜大于５％的富脉矿，脉矿与层状矿在伴生元素、稀土配分、硫同位素组成，爆裂测温等方面，二者均有明显的区别。脉铜矿是以深源为主形成的。建议对历史上曾开采，但至今未作详细地质工作的茂麓铜厂尽快予以评价。

| Abstract: | The Dongchuan rich vein deposit had historically great contribution to the mine and country.The Tangdan thick stratiform copper deposit was also discovered based upon the wide field survey for Tangdan vein ore in 1950s,that therefore approve the tremendous industral values of the stratiform ores in the whole Dongchuan mining area.The genesis of the vein ores has long been fettered by an idea that the formation of vein ores were transformed from stratiform ores by drawing on the local resources.Thus there is less achievement to appraise and study for it.On the basis of the recent historical data and research achievements of the vein ores,authors consider that there widely exist rich vein ores with copper contents>5%.The vein ores are obviously different from the stratiform ores in associated elements,REE partition,sulfur isotope composition and decrepitation etc.The vein ores were mainly formed by deep sources.We propose to appraise the Maolu copper deposit as soon as possible,that had been mined in history,but has not been detailly studied in geology up to now . |
