| 中文摘要:笔者根据孢子花粉的研究，首次确定了塔里木盆地钻井中三叠系的存在。在早三叠世孢子花粉组合中共生了以具刺的Ｖｅｒｙｈａｃｈｉｕｍ和Ｍｉｃｒｈｙｓｔｒｉｄｉｕｍ为主的疑源类化石，共有１２个属，１１个老种和２个新种。该盆地下三叠统过去认为是陆相沉积，而具刺疑源类是生长在海水中的浮游生物，因此具剌疑源类的广泛发现，说明该盆地早三叠世沉积时，距海较近，有海水侵入。 |

| Abstract:critarchs are described from the Lower Triassic of the Tarim basin for the first time and allocated to 11 genera and 13 species,among which two species are new. Acritarch, mainly Veryhachium and Micrhystridium,occur together with abundant spores and pollen grains. The lower Triassic strata of the Tarim basin were previously considered to be a continental deposition. However, the acritarchs population here described suggest that the Lower Triassic is a marine environment in Tarim basin, and perhaps a littoral deposition. |
