Based on detailed geological observation and precise dating of porphyries in combination with data available, the authors hold that the Indosinian porphyries in the Zhongdian island arc zone can be divided into two parts, i.

在较为详细的野外地质观测和精确的同位素测年的基础上，结合前人资料，将中甸地区的印支期岛弧斑岩体分为东、西两个斑岩带，东斑岩带形成于 2 1 8～ 2 0 3Ma ；西斑岩带形成于 2 4 2 。92～ 2 37.5Ma。

The sulfur and lead isotope compositions indicate that the ore_forming materials were mainly derived from the volcanic rocks and granodioritic porphyries.

硫_铅同位素指示成矿物质主要源于火山岩地层和花岗闪长斑岩脉。

Based on detailed geological observation and precise dating of porphyries in combination with data available, the authors hold that the Indosinian porphyries in the Zhongdian island arc zone can be divided into two parts, i.e., the eastern porphyry belt formed during 218～203 Ma and the western porphyry belt formed during 242.92～237.5 Ma.

在较为详细的野外地质观测和精确的同位素测年的基础上，结合前人资料，将中甸地区的印支期岛弧斑岩体分为东、西两个斑岩带，东斑岩带形成于 2 1 8～ 2 0 3Ma ；西斑岩带形成于 2 4 2 。92～ 2 37.5Ma。喜马拉雅期(5 3.0 2Ma)斑岩叠加于早期的斑岩体之上，与斑岩铜矿化关系密切。

In this his dissertation, the field geological work and modern analysis were finished on the Qulong ore-bearing porphyries. The mineralization chronology, petrology, element and isotopic geochemistry were studied on the porphyries. This dissertation also compare this work in Qulong ore-bearing porphyries with other ore-bearing porphyries in Gangdese belt, in order to probe into dynamical background and mineralization features of the ore belts in the condition of India-Eurasia collision.

在充分搜集、利用前人资料及成果的基础上，本论文力求以地球动力学和现代成矿理论为指导，采用先进的分析测试手段和野外地质工作相结合的方法，通过重点研究驱龙斑岩铜矿床的岩石学、同位素地球化学、常量与微量元素地球化学及成矿年代学，并与冈底斯其它斑岩矿床对比，探讨在印度—欧亚大陆碰撞条件下，冈底斯斑岩铜矿带的大陆动力学背景及成矿规律。

Pb-Sr-Nd isotope tracing shows that the source of magma in the island-arc belt of Zhongdian area belongs to crust-mantle mixed type. The proportion of mantle material is 59.5% crust's is 40.5%. Similarly, for the Cenozoic alkaline-enriched porphyries, the source of magma is crust-mantle mixed type, but the proportion of mantle material is increased to 54.3%.
