The asbian to arnsbergian conodonts and sequence stratigraphy of the Northumberland trough [PDF]

, 2001
Yoredale sequences are excellent exemplars of the sequence stratigraphy model; the spacial and temporal variation of these complex shallow marine/fluvio-deltaic/ coastal plain cycles, exhibit all the uiternal facies architecture that would be expected of

Mesozoic–Cenozoic Thermochronology of the Tarim–Southern Tianshan System, NW China

Geological Journal, EarlyView.
Tectonothermal history of the Tarim–Southern Tianshan system compared with the major tectonic events at far‐field plate margins. ABSTRACT The Tarim Basin, an oil‐bearing basin in northwest China, is tectonically and sedimentologically linked to the Southern Tianshan Orogenic Belt.

Replacement of Ores Recorded by Textures and Chemical Compositions of Sphalerite: An Example From the Furutobe Kuroko Deposit, Akita, Japan

Geological Journal, EarlyView.
Coupled dissolution‐reprecipitation of early formed Cd‐, Fe‐, Ag‐ and Sb‐poor sphalerite through interaction with high‐temperature and high‐sulphur fugacity Cu‐rich fluids, responsible for the formation of the yellow ores, resulted in the formation of Cd‐, Fe‐, Ag‐ and Sb‐rich, heavily chalcopyrite‐diseased sphalerite and enrichment of critical metals ...

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.

Present-day stress orientations and tectonic provinces of the NW Borneo collisional margin

, 2010
Extent: 15p.Borehole failure observed on image and dipmeter logs from 55 petroleum wells across the NW Borneo collisional margin were used to determine maximum horizontal stress (σH) orientations; combined with seismic and outcrop data, they define seven

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 ...

Development of a three‐dimensional hydrogeological model for the island of Norderney (Germany) using GemPy

Geoscience Data Journal
Geological information is required to parameterize hydrogeological properties in groundwater flow models. Our aim was to provide a hydrogeological model for the island of Norderney, Northwest Germany and the surrounding Wadden Sea for this purpose.

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.
