【摘要】 鄂尔多斯盆地上三叠统延长组长7油层组分散有机质δ13C值为(-24．5--26．6)× 10-3,主要来源C3漂浮植物,沉积期为湿热环境,并经历了4个从温湿到湿热气候的小旋回。更多还原

【Abstract】 Disperse organic carbon stable isotope value of the Upper Triassic in Erdos basin is (-24.5 - -26.6) ×10-3, and be derived from C3 plants. The paleoclimate of the Late Triassic especially Chang 7 sedimentary age acted as humid and heat, and came through tour small climate cycles from humid and wanner to humid and heater.更多还原
