The fine-grained sedimentary rock has an important position in sedimentary rocks,but it has been often overlooked because of its seemingly simple appearance.Meanwhile,due to limitation of ultra-microcosmic experimental conditions,deposition and diagenesis of fine-grained sediments remain a relatively weake research field in sedimentology,even in

· Autorun analysis of rock fractures in scanlines yields a consistent criterion of rock quality. The stress tensor is defined in a symmetric matrix. In diagonal form, the elements of the stress matrix are principal normal stresses. The Mohr’s circle in 2D and 3D is used to define normal and tangential stress in an arbitrarily oriented plane.
