英文摘要	This note reports the first discovery of Middle-late Ordovician acritarchs from the Buqingshan ophiolite complex of the southern ophiolite zone of East Kunlun, The acritarch assemblage is dominated with acanthomorphids (approx, 32%) and sphaeromorphds (approx. 63%) and contains more characteristic forms, such as Lophosphaeridium edenense, L. varum, Nothooidium sp,,? Buedingiisphaaeridinm sp,, Virbysphaera sp., Strophomorpha sp., etc. In addition, some tube-like fragments and tetrads, which are recognized as affinity to terrestrial plants and usual occurrence in Late Ordovician-Early Silurian strata, are preserved together with acritarchs. All the known fossil evidence indicates that the strata should be Middle-Late Ordovician in age. It not only provides paleontological proof for the existence of Ordovician ophiolite, but also challenges the usual ideas on strata composition of the studied area and the southern ophiolite zone of East Kunlun, and the models on tectonic framework and evolution of this area and the northern part of the Qinghai-Tibetan Plateau.
