| 摘 要： | 研究了黔东天柱磨山一油麻坳金矿带地质特征，微量元素及金赋及存状态，认为金元素来源于凝灰质板岩类地层，先期构造运动及变质作用使构造带凝灰质板岩类岩石中金元素含量进一步增高，后期热液活动使金元素活化迁移到有利构造部位成矿，金以粗晶状单体自然金及细粒金存在的石英脉及硫化物中。

| Abstract: | This paper studies the geological features,trace elements and modes of occurrence of gold in Moshan-Youmaao gold deposit in Tianzhu,East Guizhou.It points out that gold is formed in the volcanic taffaceous slate.In the initial stage,the tectonics movement and reformation made gold element enrich in strata.In the late stage,the hydrothermal action activated and transferred gold element to a favorable tectonic position to be minerilized.Gold occurs in a form of crystal grain or fine grain in the quartz veins and sulfides. |
