Abstract:

Abstract:  The lithostratigraphical system in Kalamaily Area since the Carboniferous is composed of three suits of tectonostratigraphic sequences. They are: (1) an orogenic base sequence characterized by ophiolite mélange belt with cleavages and tight folds; (2) a postcollision tectonic layer of Carboniferous with most broad folds; and (3) an intercontinental basin tectonic layer of Permian to Jurassic full of both highangle normal faults and gentle folds. They represent the characteristics of sedimentformation of preCarboniferous collision stage, Carboniferous postcollision stage and intraplate faultcontrolled depression stage of Permian, respectively.
