一、问题的提出及其意义地质力学认为:“矿产资源的分布,是受地质条件所控制的,因此,对地壳构造和地壳运动规律的正确认识,是找矿的关键”。对于滇中地区的区域成矿特点和构造控矿条件方面的队识,取决于正确地建立和划分滇中地区的构造体系;正确地认识和分析各项构造型式之间的联合和复合关系。李四光同志在广泛总结实践经验的基础上,提出了云南中部地区的南北向构造带,并指出它是我国重要的巨型成矿带之一。这一正确论断,对于认识滇中
First, the question raised and its significance Geomechanics that: “The distribution of mineral resources is controlled by the geological conditions, therefore, the right crustal structure and crustal movement of the correct understanding of the law, is the key to prospecting ”. The knowledge of the regional mineralization features and tectonic ore-controlling conditions in the central Yunnan area depends on the correct establishment and division of the tectonic systems in the central Yunnan area; and the correct understanding and analysis of the joint and compound relations among various tectonic patterns. Based on extensive practical experience, Comrade Li Siguang proposed the north-south tectonic belt in central Yunnan and pointed out that it is one of the important giant metallogenic belt in China. This correct conclusion, for understanding Yunnan
