Chemical Composition of Sandstones in Japan [PDF]
, 1981 Chmical analyses for seventy six sandstones of late Paleozoic to Tertiary age in Japan are co11ected and discussed from the geological point of view． The sandstones show distinct variations in chemical composition as well as mineralogical one in relation

The Anatomical Record, EarlyView.Abstract The Upper Cretaceous São José do Rio Preto Formation (Bauru Group, southeastern Brazil) has yielded a fragmentary but taxonomically diverse record of titanosaur sauropods, although elements from cervical series remain scarce. Here, we describe a nearly complete sauropod axis from the Vila Ventura Paleontological Area, representing an uncommon ...

Sedimentological analysis and hydrocarbon potential of the upper devonian-lower carboniferous Tahara sandstones, ghadames basin, western Libya [PDF]
, 1998 The Palaeozoic (Upper Devonian-Lower Carboniferous) Tahara Formation, western Libya, was deposited in shallow-water, marginal and nearshore marine environments influenced by waves and storms.

The Anatomical Record, EarlyView.Abstract The Aliança Formation (Jatobá Basin) represents lacustrine deposits formed in oxygenated waters that hosted a diverse fauna, including Hybodontiform sharks. Within this group, the Family Lonchidiidae comprises 11 valid genera, with Parvodus previously reported in Brazilian deposits from the Brejo Santo Formation (Araripe Basin, Late Jurassic ...

Учёные записки Казанского университета: Серия Естественные науки, 2019 Sandy deposits can have a different genesis and form in different sedimentation environments. The example of the tar sands of the Early Permian age of the Republic of Tatarstan (Russia) shows the possibility of their complex and polygenic formation with ...

Reservoir characterization and potential of the old red sandstone around the inner moray firth, NE Scotland [PDF]
, 1993 Old Red Sandstone deposition in North East Scotland occurred during Devonian times within the Orcadian Basin, a northeast-southwest elongated structure. The basin formed in an extensional tectonic regime that resulted from gravitational collapse of over ...

, 2009 Sandstone provenance studies can help constrain palaeogeographic reconstructions and ancient drainage system scales and pathways. However, these insights can be obscured by difficulties in geochemically distinguishing or adequately characterising ...

The Anatomical Record, EarlyView.Abstract Studies investigating paleopathologies in sauropods remain scarce despite their relative abundance in the fossil record. In this study we report new occurrence of paleopathological features, corresponding to a neoplasm found in a middle caudal vertebra (MCT.R.2120) of an advanced titanosaur from the Presidente Prudente Formation (Bauru Basin ...
