| 中文摘要: |
| 陕西省汉阴县黄龙金矿位于陕西石泉-旬阳金矿带整装勘查区中部,是区内重点调查的典型矿床之一,本次工作通过对黄龙金矿不同地质体的氢氧同位素、硫同位素、石英包裹体均一温度及稀土元素等方面的研究,以及成矿物理化学条件的分析,结合矿体地质特征,认为黄龙金矿床成矿物质是多源的,主要来源有3个方面:①中-下志留统梅子垭岩组；②煌斑岩脉；③早期剥离断层。通过对该矿床成矿物质来源及区内构造变形特征分析,建立了黄龙金矿岩浆热液叠加改造型金成矿模式图。为区内寻找同类型金矿床提供新的思路。 |
| 英文摘要: |
| Huanglong Gold Mine,Hanyin County,Shaanxi Province,is located in middle of the integrated exploration area of Shiquan-Xunyang gold belt,Shaanxi province,and is one of the typical deposits in the area.Based on the study of hydrogen and oxygen isotopes and sulfur isotopes,homogenization temperature of quartz inclusions and rare earth elements in different geological bodies of HuangLong gold deposit,it is preliminarily considered that the metallogenic materials of gold deposits in this area are multi-source,and there are three main sources:①Middle-Lower Silurian Meiziya formation ②Lamprophyre dike ③Early detachment fault. Based on the analysis of the source of ore-forming materials and the characteristics of tectonic deformation in the area,themetallogenic model map of magmatic hydrothermal-tectonic modified gold deposit in the area is established. It provides some reference significance for searching for the same type of gold deposits in the area. |
