本文在区划资料的基础上,综述滇西中——酸性斑岩的成岩差异性和成矿控制的共同性。论述三个方面的主要内容:1、依据区域成矿地质背景如斑岩体时空分布的特点,划分出喜山、印支两个主要的成矿期;其大地构造环境分属于岛弧区和大陆边缘区,因而出现斑岩型和似斑岩型矿床。2、与中——酸性斑岩有关的铜、钼复合矿床初步归纳了矿化岩体的主要地质特征,并划分了不同的矿化类型。3、初步阐明了岩浆岩、构造、围岩三种因素,对斑岩矿床的成矿控制作用。矿床主要受三种地质因素综合作用的结果,所不同的仅是各矿化岩体中有主、次关系的差别而已。
Based on the zoning data, this paper reviews the diagenetic differences and the commonalities of metallogenic control of the intermediate-acidic porphyries in western Yunnan. Discusses the main contents of the three aspects: 1, Based on the characteristics of regional ore-forming geological background such as the temporal and spatial distribution of porphyry bodies, the two major metallogenic stages of Xishan and Indo-China are divided. The tectonic environment belongs to the island arc zone and Continental margins, resulting in porphyry and porphyry deposits. 2. The main copper and molybdenum complex mineral deposits associated with the medium-acidic porphyry initially summarize the main geological features of the mineralized rock mass and classify the different mineralization types. 3, initially clarified the three factors of magmatic rock, tectonic and surrounding rock, and controlled the mineralization of porphyry deposits. The deposit is mainly affected by the combined effect of three geological factors. The difference is only the difference between primary and secondary in each mineralized rock mass.
