| 英文摘要 | A high- to ultra high pressure (HP-UHP) metamorphic slab resulted from deep continental subduction and subsequent exhumation is well exposed in Yankou, northeastern Qingdao in the Sulu orogenic belt, China. It consists of two kinds of structural units, namely structurally coherent unit and non-coherent unit (UHP ductile shear melange), respectively. Similar to the ultrahigh-pressure metamorphic (UHPM) rocks at other localities in the Su-Lu UHPM belt, the coherent unit consists of interlayered granitic gneiss, paragneisses, retrograde eclogite and ultramafic rocks in which coesite and other UHP minerals are widely preserved, indicating that they have an UHP metamorphic history. While the later is a ductile shear complex that consists of highly sheared mylonitic matrix and weakly deformed blocks, of which the matrix is composed of interlayered granitic and eclogitic mylonites; while the blocks are granitoids and gabbro that are metamorphosed to a variable degree of coesite eclogite facies. The two units are separated by an ultramylonite zone of 20 similar to 30 cm wide, and the non-coherent unit structurally lies below the coherent one. |
