Ultra-shallow-marine anoxia in an Early Triassic shallow-marine clastic ramp (Spitsbergen) and the suppression of benthic radiation [PDF]

, 2015
Lower Triassic marine strata in Spitsbergen accumulated on a mid-to-high latitude ramp in which high-energy foreshore and shoreface facies passed offshore into sheet sandstones of probable hyperpycnite origin.

Genesis and reservoir preservation mechanism of 10 000‐m ultradeep dolomite in Chinese craton basin

Deep Underground Science and Engineering, EarlyView.
Potential exploration target stratum of 10 000‐m ultradeep dolomite in Sichuan Basin and Tarim Basin, China. Abstract The 10 000‐m ultradeep dolomite reservoir holds significant potential as a successor field for future oil and gas exploration in China's marine craton basin.

Facies, development and interpretation of sedimentary environment of the uranium-bearing Brebovnica Member of the Val Gardena Formation in the Žirovski vrh area, W Slovenia

Geologija, 2002
The Brebovnica Member, bearing considerable grades of uranium ore, is the most important member of the Val Gardena Formation. Rocks were subdivided according to grain size, sedimentary structures and composition to conglomerate, sandstone, mudstone and ...

DEPOSITIONAL ARCHITECTURE, FACIES CHARACTER AND GEOCHEMICAL SIGNATURE OF THE TIVOLI TRAVERTINES (PLEISTOCENE, ACQUE ALBULE BASIN, CENTRAL ITALY)

Rivista Italiana di Paleontologia e Stratigrafia, 2017
Facies character, diagenesis, geochemical signature, porosity, permeability, and geometry of the upper Pleistocene Tivoli travertines were investigated integrating information from six borehole cores, drilled along a 3 km N-S transect, and quarry faces ...

Mangarara Formation: exhumed remnants of a middle Miocene, temperate carbonate, submarine channel-fan system on the eastern margin of Taranaki Basin, New Zealand [PDF]

, 2009
The middle Miocene Mangarara Formation is a thin (1–60 m), laterally discontinuous unit of moderately to highly calcareous (40–90%) facies of sandy to pure limestone, bioclastic sandstone, and conglomerate that crops out in a few valleys in North ...

SFA-GTM: Seismic Facies Analysis Based on Generative Topographic Map and RBF [PDF]

arXiv, 2018
Seismic facies identification plays a significant role in reservoir characterization. It helps in identifying the various lithological and stratigraphical changes in reservoir properties. With the increase in the size of seismic data or number of attributes to be analyzed, the manual process for facies identification becomes complicated and time ...

Semiconductor Lasers and Kolmogorov Spectra [PDF]

, 1997
In this article, we make a prima facie case that there could be distinct advantages to exploiting a new class of finite flux equilibrium solutions of the Quantum Boltzmann equation in semiconductor lasers.

Petrogenetic and geochemical characteristics of some auriferous granitoids in the Kumasi Basin, Ghana: Implications for geodynamic settings and controls of orogenic gold mineralization in the Edikan Gold Mine

Deep Underground Science and Engineering, EarlyView.
The Fobinso granitoids are granodiorites, while the Esuajah granitoids are granites based on their mineralogical composition. The granitoids are generally enriched in LILE and LREE than HFSE, MREE, and HREE, indicating mixing with crustal sources during their evolution.

The Chuquibamba Landslide Western Cordillera, Peru revisited: New Evidence of a Dry Debris Avalanche

Geofísica Internacional
Landslides represent a serious mountain hazard to lives and infrastructure, especially when geological factors such as highly fractured rocks, faulting, steep topography, and weathering combine with seismic triggering factors.

Inversion using a new low-dimensional representation of complex binary geological media based on a deep neural network [PDF]

, 2016
Efficient and high-fidelity prior sampling and inversion for complex geological media is still a largely unsolved challenge. Here, we use a deep neural network of the variational autoencoder type to construct a parametric low-dimensional base model ...
