Abstract Stratigraphic investigations, supported by palynological dating, detrital zircon and monazite dating, and quartz grain micromorphology were undertaken of the Early Cretaceous strata around the southern margin of the Eromanga Basin where they onlap older rocks of the northern Flinders Ranges. The presence of a tillite within the Early Cretaceous Cadna-owie Formation and another in the Trinity Well Sandstone are evidence of two significant glaciations: the oldest, the Livingston Tillite Member, is from the middle Valanginian; the younger, the Sheehan Tillite Member, is from the early Aptian. A significant hiatus encompassing the Barremian interrupts the succession. Extensive dropstones, minor diamictite lenses and beds and a bed containing glendonite crystals, together indicate that cold (limited glacial and/or seasonal freezing) conditions persisted through the Hauterivian and the Aptian, with cold conditions peaking in the late Aptian.

早白垩世高纬度南澳大利亚的冰川作用

摘要 以孢粉学测年、碎屑锆石和独居石测年以及石英颗粒微形态学为支持的地层调查研究是在 Eromanga 盆地南缘周围的早白垩世地层中进行的，这些地层与弗林德斯山脉北部的老岩石重叠。早白垩世 Cadna-owie 组和 Trinity 井砂岩中存在一种铁屑岩是两种重要冰川作用的证据：最古老的 Livingston Tillite 成员来自 Valanginian 中期；年轻的，席汉提利特成员，来自早期的阿普提安。包括 Barremian 在内的重大中断中断了继承。大量的滴石、次要的硅藻土透镜和床以及含有菱镁矿晶体的床，
