| 中文摘要: |
| 通化市江沿金矿位于通化南金多金属成矿带的中部。Ⅱ号矿化蚀变带内的1号矿体是该区目前发现的较为重要的矿体之一。该矿体含矿岩石为长石斑岩,载金矿物主要为黄铁矿。文章通过对1号矿体地质特征的观察与研究,认为长石斑岩本身就是含矿体,属岩浆成因的产物,受F402断裂的次一级构造控制。1号矿体无论是矿体品位、蚀变程度及矿体规模等,均有向下逐渐变富、变强、变大的趋势。 |
| 英文摘要: |
| Yanjiang gold deposit, Tonghua, is located at the central of the south Tonghua gold and polymetallic metallogenic belt. The orebody 1 in the mineralization zone II, is one of important orebodies discovered in this area. The host rock of Orebody 1 is feldspar porphyry and host mineral of gold is pyrite. By the observation and research on the geological characteristics of the Orebody 1, we proposed that feldspar porphyry itself is orebody, produced from igneous activity, and controlled by the secondary fracture of Fracture F402. The grade, alteration level and size of Orebody 1, all shows becoming higher, stronger and larger to the deeper. |
