| Abstract | 本文对月山岩体和安庆铜矿地球化学、矿床成矿流体、以及成岩成矿地球动力学背景等方面进行了系统研究，主要取得了如下几点认识： 1：月山岩体为燕山早期由壳幔AFC作用形成的富碱闪长岩体。 2：成岩与成矿作用密切相关，夕卡岩可能为接触交代成因。 3：成矿流体属盐水体系，主成矿阶段发生了流体混合作用和沸腾作用。 4：成岩成矿作用发生在拉张或向拉张过渡的背景下。 5：初步建立了安庆铜矿流体演化与成矿模式。 |
| Other Abstract | In this paper, we mainly focused on the petrology, elemental geochemistry, metallogenic geodynamics and fluid inclusions of the Anqing skarn-type Cu-Fe deposit and Yueshan intrusion. The main conclusions are listed as follows: 1. The Yueshan consists of alkali-rich diorites, which were formed by crustal materials and mantle-derived high-K alkalic basaltic magma in the early Yanshania period. 2. The intrusion and the orebody have close genetic relationship; all skarns show the characteristics of metasomatism skarn. 3. The ore-forming fluid belongs to NaCl-KCl-H2O solution system, boiling and mixing of fluids occurred in the major ore-forming stage. 4. The petrogenesis and metallogenesis took place in a transitional period from postorogenic to tensional tectonic environment 5. A preliminary model for the ore-forming process of the Anqing skarn-type Cu-Fe deposit is proposed. |
