After dealing briefly with the development of the concept of meta llotectonies, the paper discusses preliminarily deep-seated structure, tectonic-geochemistry of metallotectonics, and application of the symme tric theory to metallotectonics. The author consider:A) The study of deep-seated structure(geophysic field)is one of the basic contents of metallotectonics. Through study of geophysic features, we can get data on the structure of the crust, the features of vertical or lateral variation of every layer, undulate variation of Moho disconti nuity, structural variation of areas between continental crust and oce anic crust, etc. On the basis of the data, metallogenic regularities are analysed, and mineral deposits are prognosticated. B) The study of tectonic-geochemistry is a key to metallotectonics. The formation of ore-forming elements geochemical anomalies is not only closely related tp the fractional development stages and produc tions of tectonic-geochemistry of the crust but also controlled by de velopment features which they were undergone after their formation.C) In the last years, application of the symmetric theory to metallo tectonics is further progessive. Many scientists of our country and other countries have applied the theory to metallotectonics of different scales and types, and have achieved some successes in metallogenic progno stication and prospecting. The equidistances of metallogenic structures may be divided into three types: concentric equidistance, en echelon equidistance, parallel equidistance. Their formation mechanism may be related to spreading manner of stress wave.

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。

Tectonic gcchcmistry is a new branch of learning involving many problems of both geochemistry and tectonic geology. Its fundamental theory is based upon stress field theory, chemical dynamics and dissipat on structure theory and its contents deal with geochemlstry problems of geo-tcctonics, regional tectonics, ore-field (ore deposit) structure and microtectonics. Mcthods of tectonic geochemistry investigation include comprehensive geological studies, geochemical survey and experimental investigations.
