甘肃隆瓦寺院金矿中性岩脉与成矿关系探讨

The Relationship Between Neutral Dike And The Ore-Forming Of The Longwasiyuan Gold Deposit In Gansu Province

隆瓦寺院金矿床位于西秦岭褶皱带的北部断褶带与中部裂陷槽之间的过渡部位,中性岩脉与成矿在时间、空间分布上具有密切联系。本文在总结前人勘查成果的基础上,通过对矿区岩脉岩性特征、时空分布特征及脉岩型矿石与其他类型矿石微量元素特征作对比,对其与金矿化的关系进行分析,探讨岩脉在该矿床形成中的作用及对金的找矿工作的指示意义。

Longwasiyuan gold deposit bed in west Qinling fold belt of northern fault fold belt and central chasmic trough the transition between the parts,neutral dike and mineralization has a close connection.Onthe basis of summarizing the predecessors'research achievements,this article explore the role of dike in the ore deposit formation through the mining characteristics of dike,space-time distribution and the characteristics of trace elements and the relationship between gold mineralization and ore analysis,Results show that the gold mineralization in time and space distribution and metallogenic material sources have close relationship with neutral dike,neutral dike indicating significance for gold prospecting.
