| 摘 要： | 工作区位于泽库弧后前陆盆地,在长期沉陷的断陷盆地中沉积的三叠纪古浪堤组成了赋矿地层,构造运动以及印支期中酸性岩浆活动使金富集成矿。区内晚三叠世花岗闪长岩与古浪堤组内外接触带和构造破碎蚀变带中具有寻找构造蚀变岩型金矿的条件。本文初步总结了工作区内的金矿成矿地质背景、找矿标志,根据已发现的找矿线索对找矿前景做以浅析,以期对下一步找矿工作提供借鉴和指导。

| Abstract: | The survey region is located in foreland basin of the Zeku arc , ore-bearing strata was disposed of Triassic Gu-lang dikes in long-term subsidence of rift-subsidence basin ,gold-rich ore was enriched by the tectonic movement and Indo-Chinese intermediate-acid magmatism.Prospecting condition for structural altered rock type gold deposit exists in Late Tri -assic granodiorite , in Gulang Group contact zone and structure fractured alteration belts .This article sums up the regional gold ore-forming geological background , prospecting according to former clues , and provides reference and guidance for fur-ther work. |
