摘要
对德兴铜矿铜厂和富家坞花岗闪长斑岩样品的微量元素和稀土元素分配特征分析研究表明,铜厂和富家坞两个矿区的花岗闪长斑岩具有一致的来源,两个斑岩体均由混有少量地壳物质的地幔岩浆演化而来。结晶分异作用可能是岩浆演化的主要原因。
In this paper, the characteristics of trace elements and rare earth elements of the granodiorite-porphyry from the Dexing copper ore district are studied. The conclusion can be reached that the granodiorite porphyry of Tongchang and Fujiawu ore-field have the same origin. The Tongchang and Fujiawu granodiorite porphyry are all derived from the magma of the primitive mantle, and cotaminated by the crustal material, and may be formed mainly by crystalization differentiation.
