英文摘要 | The Tieshidas Group in Qimantag, a branch of the East Kunlun Mountains, was classically considered the Caledonian basement, and classified into Middle-Upper Ordovician, Upper Ordovician or simply Lower Paleozoic. The radiolarian fauna was found, for the first time, from a chert block in the Tieshidas Group at Yaziquandaban (Pass) north to Ayakum Lake. They are Astroentactinia? mirousi Gourmelon, As. ct biaciculata Nazarov, Archocyrtium of. diductum Deflandre, Ar. aff, diductum Deflandre, Deflandrellium? sp., Entactinia vulgaris Won, En. of. additiva Foreman, En.? sp., Entactinosphaera palimbola Foreman, Pylentonema? sp., Triaenosphaera sp. and Tr.? sp. The geological age of this radiolarian fauna is Early Carboniferous, Evidently, the classical interpretation about the age of Tieshidas Group needs to be checked and modified. Except the Ordovician proved with the formerly discovered fossils, it also includes, at least, Lower Carboniferous rocks. There was still an oceanic basin at Qimantag during Early Carboniferous (and even a long geological time after then). Qimantag is not a Caledonian fold belt, and the Tieshidas Group is not the Caledonian basement. |
