摘    要：对本区的构造体系及其与控岩控矿的关系,目前尚存在不同认识。本文在前人工作的基础上,根据一年多来在这个地区的野外实践和室内模拟实验提出:区内有北西西向联合构造、淮阳山字型前弧西翼,新华夏系等三个构造体系,而北西两向联合构造是本区构造格架的基础,亦是本区的主要控岩控矿构造。并在此基础上,提出了今后的找矿方向和进一步工作的重点。

Abstract: The pointviews toward the classification of tectonic systems and their relationships with rock and ore control in the igneous complex area of E city, Hubei are so far diverse greatly. On the basis of others’ previous work and according to authors’field investigation and model experiment carried out more than one year it is concluded in thispaper that there are three categories of tectonic system in this area namely NWW-trending combined structure, Huaiyang epsilon-type structure, and Neocathaysian structural system; the MWW-trending combined structure, however, is believed to be the foundation of structural framework as well as the dominant strucsure controlling the distribution of igneous rock amd ore depostes in this area; the direction of prospecting ore deposits and the focal point of futher exploration work are proposed.
