COMPOSITIONS OF TECTONIC MELANGE IN WUNUER AREA,DAXINGANLING MOUNTAINS:Geological Implication
摘要
Abstract
The Wunuer tectonic melange is composed of rock blocks and matrixes with different properties,belonging to sandy tectonic melange.The blocks can be sorted into local blocks and exotic blocks,which are various in size,composition and shape,disorderly distributed in the melange.The matrix is foliated argillaceous rock or phyllite slate,with intense shear deformation and disordered schistosity,distributed around the blocks.The comprehensive study shows that the Wunuer tectonic melange,obviously different from the slump deposit of sedimentary origin,is a typical sandy tectonic melange,serving as an important part of Xinlin-Xiguitu suture zone.关键词
