本文在简述成矿构造概念的演进之后,对成矿构造理论中的深部构造、构造-地球化学的研究及对称理论在成矿构造中的应用等问题,进行了初步研究。作者认为: 1.深部构造(地球物理场)的研究是成矿构造理论研究的一项基本内容。目前主要通过地球物理特征的研究,籍以提供地壳结构,各壳层的垂向或横向变化特征,深部莫氏面的起伏变化,犬陆壳与大洋壳相邻部位的结构变化等方面资料,在此基础上,进行成矿规律分析和矿产预测。 2.构造-地球化学的研究是成矿构造理论研究中的一个关键问题。成矿元素地球化学异常场的形成,与地壳构造、地球化学分异演化阶段和产物的成因紧密相关。同时,又受地球化学异常场形成后其所经历的发展特征所控制。 3.对称理论在成矿构造研究中,近年来有进一步发展。国内、外的学者,把对称理论应用于大、中、小不同类型的成矿构造,在成矿预测、找矿勘探中取得了比较好的效果。对成矿构造的等距性初步可划分为:同心等距、斜列等距、平行等距三种不同类型。其形成机理可能与应力波的传播方式有关。
After briefly describing the evolution of the concept of metallogenic tectonics, this paper carried out a preliminary study on the deep tectonics, tectono-geochemistry and the application of symmetry theory in metallogenic tectonics. The author thinks: 1. The study of deep structure (geophysical field) is a basic content of the research on the theory of metallogenic structure. At present, mainly through the study of geophysical characteristics, to provide information on crustal structure, vertical or horizontal variation characteristics of various crusts, ups and downs of the Mohe surface in deep, structural changes of the adjacent parts of the dog’s crust and the oceanic crust, On this basis, the metallogenic regularity analysis and mineral prediction are carried out. 2. Tectonic-geochemical research is a key issue in the study of the theory of metallogenetic structure. The formation of the ore-forming element geochemical anomaly field is closely related to the genesis of crustal structure, geochemical differentiation and evolution and product formation. At the same time, it is controlled by the developmental characteristics experienced by the formation of anomalous geochemical field. 3. Symmetry theory In the study of metallogenetic structure, there have been further developments in recent years. Scholars at home and abroad have applied the theory of symmetry to different types of metallogenic structures of large, medium and small size and have achieved good results in mineral prospecting and prospecting. Isometrics of the metallogenic structure can be divided into three types: isometric equidistance, diagonal equidistance and parallel equidistance. Its formation mechanism may be related to the propagation of stress wave.
