摘要
新华夏系是中国东部极为重要的一个构造体系,对它的研究对阐明构造体系的改造历史具有重要的意义,尤其是研究它与其他构造体系的联合和复合形成的构造格局对、成矿控制具更重要的找矿意义。本文着重从构造体系的历史分析,讨论了新华夏与东西带及北西向构造的联合和复合问题。提出了新华夏复合式构造和新华夏联合式构造两种构造型式。
During the proceeding of the Neocathaysian, on the one hand, it was compounded and reformed with the preexisting palaeostructural system, for-ming compounded (composite or complicated) structure; on the other hand, it was combined with revivable previous (early-stage) structural system, for-ming conjunct structure. There are four types of compounded and con-junct structures. The NNE—trending compressive structure plane is of great significance during compounding and combining of Neocathaysian. To start with historical analysis of structural system, the pressent paper emphasizes to discuss the relationship of combining and compoundin between the Neocathaysian and E—W—trending zone and NW-trending struc-ture.
