The results indicate that the tempestite in the area has lots of rock types including clastic rocks, bioclastic limestones and volcaniclastic rocks. The cumulative probability plots have "high slope-multi-bouncing population-1 suspension population" pattern, multi segments pattern and "high slope 1 segment" pattern. The sedimentary structures include gutter cast, surface of scour, cut structure, graded bed, massive bedding, hummocky cross stratification, parallel bedding, ripples, contemporaneous deformation and Fugichnia. The grains distribution and sedimentary structures shier that the transportation medium is characterized by tractive current and gravity flow synchronously.
