ON THE GLIDING-DECOLLEMENT STRUCTURES DEVELOPED DURING INDOSINIAN-EARLY YANSHANIAN EPOCH IN THE NINGZHEN MOUNTAIN RANGE

Liu Shaofeng (China University of Geology ,Wuhan)  
The gliding-decollement systems at multiple levels took place within the Mesozoic-Palaeozoic marine sedimentary sequences. During Indosinian-Early Yanshan,due to first regional gravitation and then pushing-compression occurred in the area,the continuous and progressive decollement-defor-mation developed along different horizons within the sedimentary sequences,bringing about gliding decollement structures. The main patterns of the structure are of box-foldings,decollement along the horizons,and folding-overthrustings. In this paper,it is proposed that there are two models for the gliding decollement structures,i, e. decollement with overthrusting during Indosinian epoch and over-thrusting with d. ecollement in Early Yanshan.
