Heiyingshan is located in the Meisibulake pasture, 60 km northeast of Baicheng County, Xinjiang Uygur Autonomy Region, NW China. The Meisibulake ophiolitic m lange section is well exposed between the Silurian greenschist facies meta-deformation zone to the north and the overlying Carboniferous sandstone and limestone zone. The ophiolitic m lange zone is composed of mafic-ultra mafic rocks, limestone, chert blocks and flysch metrix. The mafic-ultra mafic rocks, limestone and chert are presented as the faulted blocks included within the sheared matrix that consists of muddy chert and siliceous mudstone. Radiolarian fossils are found in both chert block and siliceous matrix, including some entactinids and archocyrtids, which are identified to be Late Devonian to Early Carboniferous in age. This suggests that the age of the m lange should be a little later than that of the real ophiolite. It, therefore, could indicate that the lower limit of the closure age of the Southern Tianshan Ocean should be the Early Carboniferous, implying an initial age of the melange. Synthetic analyses with previous results indicate that the ophiolitic m lange segments distributed in Wuwamen, Kule Lake, Yiqikelik and Heiyingshan have similar petrotectonic assemblages and age, they constitute a large-scale Late-Paleozoic tectonic suture zone in Southern Tianshan collision.
