新疆昆仑山乌斯腾塔格—喀拉米兰晚三叠世植物化石的首次发现

FIRST DISCOVERY OF LATE TRIASSIC FLORULE IN WUSITENTAG-KARAMIRAN AREA OF KULUNB MOUNTAIN OF XINJIANG

新疆昆仑山乌斯腾塔格—喀拉米兰地区晚三叠世植物群Drepanozamites nilssoni-Otozamites indosinensis-Thinnfeldia nordenskioldi-Glossophyllum sheisense等的首次发现,揭示了该地区中国南方型晚三叠世植物群的面貌.对研究新疆南部地区晚三叠世地层、中国地层区划及晚三叠世植物群地理分区、以及板块构造等均具有重要意义.

Late Triassic florule and its non-marine upper Triasgic Wolonggang Formation were first discovered in Wusitentag-Karamiran area of Kunlun mountain, Xinjiang. The florule were mainly composed of Drepanozamites milssoni, Otossamites indosi-nensis, Tfcinnfe/sia nordenskioldi, and Glossophyllum shensiense, showing the features of late.TriaSsic florule of South China. In detailed descriptions and analyses of its compositions, characteristics and geographic distributions, the paper discussed the important significance of this discovery on the study of late Triassic strata, strati-graphic divisions and geographic distributions of plants, and associated plate tectonics in southern Xinjiang.
