The Qaidam Basin is one of the major coal-bearing basins in northeastern China with coal seams mainly preserved Lower–Middle Jurassic. Middle Jurassic sedimentary environment, sequence stratigraphy, paleoclimate, and accumulation have been extensively studied, while characteristics depositional evolution Lower series are less well known. We systematically analysed facies association, system, ba...

The chronologies of many lacustrine records suffer from radiocarbon reservoir effects due to the presence of dissolved `dead' carbon or to slow air^water exchange. Here we use the TIMS uranium^thorium disequilibrium method, in conjunction with AMS radiocarbon dating, to determine the age of lacustrine carbonates and to quantify the past radiocarbon reservoir effect in two Antarctic lakes with d...

The Mesozoic lacustrine revolution (MLR) represents a major evolutionary event in the continental realm (Cohen 2003 ). The decline in taxic diversity at the family level in lacustrine environments that took place during the late Paleozoic–Middle Triassic was reversed later in the Mesozoic, with diversifi cation seeming to have continued to the Quaternary, although potential biases may have affe...

Carbonates of the Ojo Huelos Member of the San Pedro Arroyo Formation include ostracodal limestones, brecciated micritic limestones, vuggy, mottled limestones, peloidal graistones/packstones, pisolitic rudstones and nodular limestones. These lithofacies record deposition in lacustrine, palustrine and alluvial environments. Lacustrine (ostracodal) limestones are isotopically heaviest, with nodul...

A large number of terrestrial mammalian fossils were reported in the well-exposed Paleogene and Neogene fluvio-lacustrine strata in Western China. Their accurate ages are crucial to understand the mammalian and environmental evolution associated with the step-wise uplift of the Tibetan Plateau. At present their ages are surprisingly poorly constrained. Here, we present a high-resolution magneto...
