Geological Characteristics and Tectonic Evolution of Mamianshan Hyperplastic Miscellaneous Rock in Central—northern Fujian Province
On the basis of systematically summing up the spatial distribution characteristics of the"Mamianshan hyperplastic miscellaneous rock"and the geological characteristics of different rocks,the new proterozoic continental arc,new proterozoic dive hyperplasia zones were divided in the region,and a series slivers of hyperplastic miscellaneous rock are further divided.The formation,development and evolution of the accretionary complex in Mameishan can be divided into five stages.The ancient south yangbasin related to the formation of mamianshan hyperplasia began to develop from the new Proterozoic.Finally,the conversion process was completed from the end of the early Paleozoic to the beginning of the late Paleozoic.With the conversion of ocean-land,the subduction of the oceanic plate causes the oceanic basin formation system into the subduction and hyperplasia activities,forming the matrix and rock series of hyperplastic miscellaneous rock.After the formation of the Mamianshan hyperplastic miscellaneous rock,it experienced multiple stages of intracontinental structure superposition and transformation,thus forming the current geological pattern.
