摘要
Gongyiming-Gaojiacun ductile deformation belt is located in near the contact zone of the Archean granite greenstone belt and high-grade metamorphic rock,in space nearly EW direction,being thrust ductile deformation belt from north to south.The ductile belt was modified by two deformation phases,the early deformationwhich was mainly ductile deformation mechanism,took place in the conditions of amphibolite facies of deep crustal tectonic levels.The late deformation one,which was mainly ductile-brittle deformation mechanism,took place in middle-shallow tectonic level of the crust.In ductile deformation belt,the main tectonite is the tectonic schist,which was consist of new flaky minerals and fibrous minerals.The macrograph and micrograph asymmetrical flow fabrics shows that movement direction of ductile deformation belt was thrusting from north to south.The ductile compression thrust deformation took place in late Archean,being relate to the collision between the northern granite greenstone belt and the southern high-grade metamorphic rock.
