【Abstract】 The cores collected from outcrops of Kuqa depression, Keping uplift and Bachu uplift in Tarim basin involve three main types of rock (i.e. metamorphic rock, igneous rock and sedimentary rock), thirty three horizons (Pt-N 2k) and fifteen kinds of lithology. The rock mechanic factors (modulus of elasticity, Poisson’s ratio and compressive strength) of 215 sets of samples were tested and analyzed. The rock mechanic features, deformation behavior and their major influential factors were studied; and a comprehensive profile of rock mechanics in Tarim basin was established. Combining with previous studies, five major detachment layer systems were proposed, improving the divisions of detachment layer systems and tectonized layers and providing solid experimental evidence for studying deformation behavior of a basin.更多还原
