五台山—恒山地区变质岩系构造相相变成因分析
Cause Analysis on the Phase Transition of the Tectonic Facies of the Metamorphic Rock Series in the Wutai Mountain-Heng Mountain Areas
摘要
Abstract
Areas in the Wutai mountain-Heng mountain are considered to be one of the most popular places for the tectonic facies researches owing to the various structural characters at different crust levels. In the present study, the structural characteristics of the Early Precambrian were analyzed. On the basis of the different geological characters of fold, fracture, pudding of the rock and syntectonic crystallization, some references were provided for analyzing the tectonic facies and the structural phase transition in the areas. Combined with the information of the geological characteristics, petrology, deformation,and metamorphic characteristics,and isotope chronology of the geological unit,the preliminary studies were conducted on the tectonic environment of the the Early Precambrian in the areas, and discussions were made on the crustal evolution andthe cause of the tectonic facies phase transition. The phenomena occurring commonly in the Metamorphic rock areas was explained reasonably,that is, the alienation between the same rocks and the convergence between the different rocks,or the same thing with different phases and the same phase with different faces. All of these provided the new research thinking and the working methods for the metamorphic rock areas.The high-grade regions of the Hornblende granulite phase in the Heng mountain areas represent the mid-lower crust's transitional zone and detachment zone. Their and it's typical structural styles, material composition, metamorphism and the effects of the deep melting have important significance on the researches of the mid-lower crust's rheological behavior, crustal differentiation and the cracking events for early continent.关键词
