| 中文摘要: |
| 10号是玲珑金矿田内发育的一条高角度断裂,构造岩破碎,结构松散。除其内部碎裂石英脉部分重新胶结外,其他构造岩均未胶结。经过构造特征分析,其形成于主成矿阶段,而后期又发生多次活动,近几年在该断裂中发现了具有工业价值的矿体,通过剖面与平面地质资料的对比分析、化学取样分析及玲珑金矿田成矿时期研究,10号断裂内发育的工业矿体属早期形成的石英脉矿体与后期断裂叠加的结果,早期形成的石英脉在构造动力作用下发生破碎并分散到断裂带中,加上金元素在地质历史时期内发生短距离运移,形成了目前的工业矿体。10号断裂多次活动对早期形成的矿脉起破坏作用并使金元素重新分配。 |
| 英文摘要: |
| The No.10 fault in Linglong gold ore field is a high angle fault with fractured tectonite and loose texture.Only the fractured quartz veins are recemented.The structural analysis shows that it was formed at the main ore stage and multiple late movements took place.Economic ore bodies have been discovered within it in recent years.Analysis in its section and plan together with chemical analysis of the collected samples and study on ore stages reveal that the existing ore bodies in the fault are the result of overprint of late fracturing on the early-formed quartz vtins.The quartz veins were fractured and dispersed in the fractural zone under tectonic dynamics during which gold was transported in short distance to form the gold ore bodies.The fault destroied the early quartz vein and brought about Au redistribution. |
