Using DZmix and DZstats models, we quantified the contributions of potential sources of the Lanzhou basin. Our findings indicate that the Cenozoic cooling and denudation signals primarily originated from Qilian and West Qinling, which were the main sediment sources.

A Middle and Late Devensian sequence from the northern part of Kents Cavern (Devon, UK)
Abstract 1920s/30s excavation of a Middle Devensian sequence in the northern part of Kents Cavern recovered important Late Middle and Early Upper Palaeolithic archaeological material, including Britain's oldest known Homo sapiens remains. Questions remain about this material, including how it came to be in the cave.

The Jurassic/Cretaceous boundary and high resolution biostratigraphy of the pelagic sequences of the kurovice section (Outer Western Carpathians, the northern Tethyan margin) [PDF]
Microfacies and high resolution studies at the Kurovice quarry (Czech Republic, Outer Western Carpathians) on calpionellids, calcareous and non-calcareous dinoflagellate cysts, sporomorphs and calcareous nannofossils, aligned with paleomagnetism, allow ...

ABSTRACT Northwest Europe experienced high‐amplitude climate change at the onset and end of the Younger Dryas (YD; ca 12 800–11 600 cal a BP), a crucial period to develop our understanding of natural climate dynamics. European palaeoclimatological records generally suggest a bipartite structure of the YD, potentially due to a northward retreat of the ...

The Piedmont Tertiary Basin (PTB) is bounded southwards and westwards by the Western Alps, and northwards by the north-western end of the Apennines. It develops internally to a south-dipping suture zone, on a basement consisting of allochthonous alpine ...

A calcareous nannofossil and organic geochemical study of marine palaeoenvironmental changes across the Sinemurian/Pliensbachian (early Jurassic, ~191Ma) in Portugal [PDF]
The Sinemurian/Pliensbachian boundary (~ 191 Ma) is acknowledged as one of the most important steps in the radiation of planktonic organisms, especially primary producers such as dinoflagellates and coccolithophores.

ABSTRACT The semi‐arid Australian continental inland is increasingly subject to climatic extremes such as drought and flooding. Combined with the exceptionally low topographic relief characteristic of this region, hydroclimatic extremes can have an enormous impact on the land surface.
