From Proterozoic flysch deposits in the Qimen-Shexian region of southern Anhwei some evidences of turbidite have been discovered. The flysch deposits are widely distributed over the "South China Old Land" including the southern part of Anhwei province, where suites of preorogenic volcanic rocks were found recently in a few localities. Evidently, the primary tectonic environment of Proterozoic metamorphics concerned should be part of a eugeosynclinal or trench and in the region under study there may be found volcanic rocks underlying the flysh deposits which were overlain by synorogenic volcanic rocks.From each group of metamorphie rocks can be distinguished four periods or generations of folding deformation. During deformation the dynamic axis "C" rotated clockwise in ascending order, or in other words from east toward west. Besides, the intensity of folding and the ductility of rocks decreased gradually. Some metamorphics show simple folds which resemble those of the Appalachian fold belt in pea-nsylvania and the nearby States as well as those of the fold belt in the centre-western part of New South Walse.
