摘要
研究了石湖金矿床岩浆岩、近矿围岩及金矿床矿石稀土元素的地球化学特征。结果表明,石英闪长玢岩和麻棚岩体在稀土元素总量、轻稀土富集程度、轻重稀土分离程度、铕异常以及元素配分模式方面都较相似,反映两者在岩浆物源上具同源性;近矿围岩中斜长片麻岩和黑云斜长片麻岩稀土元素总量最高,反映了麻棚岩体和石英闪长玢岩具同源性,矿石同近矿围岩具同源性。
Geochemical characteristics of magmatic rocks, surrounding rocks and rare earth elements in Shihu Gold Deposit are studied. The results show that there are similarities between quartz diorite porphyrite and rock mass in Mapeng in total rare earth elements, enrichment degree of light rare earth elements, separation degree of light rare earth elements and heavy rare earth elements, abnormity of europium and distribution patterns of elements, reflecting homology of the quartz diorite porphyrite and rock mass in their magma source. This research also shows that plagioclase gneiss and biotite plagioclase gneiss of the surrounding country rocks have the maximum rare earth elements. It indicates that the rock mass in Mapeng and the quartz diorite porphyrite have homology, and ore and the surrounding roeks have homology.
