Why is stromatactis so rare in Mesozoic carbonate mud mounds? [PDF]
, 2001 peer reviewedThe sedimentary-diagenetic structure stromatactis is wide-spread in Palaeozoic spiculitic carbonate mud mounds, but occurs only sporadically in Mesozoic sponge carbonate mud mounds.

Notable Impact of Paleotectonic Stress on Gold Mineralisation in the West Qinling Orogen
Geological Journal, EarlyView.By applying fuzzy clustering and multiple inverse methods, we systematically processed the data of vein and fault slip in this ore deposit to reveal the transition of orogenic geological environment and paleotectonic stress field. Our research results show two different stress states: the northwest–southeast extensional stress field and the northeast ...

Hand and foot morphology maps invasion of terrestrial environments by pterosaurs in the mid-Mesozoic [PDF]
Pterosaurs, the first true flying vertebrates, played a crucial role in Mesozoic terrestrial ecosystems. However, our understanding of their ability to move around on the ground and, more broadly, their terrestrial paleoecology remains limited.

Multiphase Tectonic Process With Slab Dynamics in the Northern East China Sea Shelf Basin
Geological Journal, EarlyView.Megasequence 1 characterised by Palaeocene extension and differential subsidence driven by the rollback of the subducting Izanagi Plate. Megasequence 2 records a kinematic reorganisation of the East Asian margin, transition from a rifting to a compressional regime.

Isotopic characterization of Jurassic evaporites. Aconcagua-Neuquén Basin, Argentina [PDF]
, 2005 Isotopic analysis can be used to interpret the origin of evaporitic sediments. A preliminary isotopic study of strontium, oxygen and sulphur has been carried out in Ca-sulphate facies of Jurassic marine evaporates (Tábanos Formation and Auquilco ...
