Metasediments of the deep crustal section of Southern Karnataka [PDF]

open access: yes
A review of the rocks of supracrustal origin in the amphibolite and granulite facies terrane in southern Karnataka was presented. In addition to introducing the metasediments in the field area of the workshop, a review was presented of the common ...

Impact of volcanism on the sedimentary record of the Neuquén rift basin, Argentina: towards a cause and effect model [PDF]

open access: yes, 2018
The analysis of volcano-sedimentary infill in sedimentary basins constitutes a challenge for basin analysis and hydrocarbon exploration worldwide. In order to understand the contribution of volcanism to the sedimentary record in rift basins, we study the

Weichselian–Holocene glacial history of the Sjuøyane archipelago, northern Svalbard

open access: yesBoreas, EarlyView.
To reconstruct the glacial history of Sjuøyane, we describe coastal sedimentary sections in Quaternary sediments and constrain their chronology by radiocarbon and optically stimulated luminescence ages. The sedimentary sections largely consist of shallow (glacio‐)marine and/or littoral sediments deposited during high relative sea levels.

Petrophysical and geochemical characterization of the late-variscan Santa Eulália Plutonic Complex (Ossa-Morena Zone, Portugal) [PDF]

open access: yes, 2012
The Santa Eulália Plutonic Complex (SEPC) is a calc-alkaline granitic body located in the northern part of the Ossa Morena Zone, composed by a medium- to coarse-grained pink granite (G0 group) involving large elongated masses of mafic (gabbroic) to ...

Generating Geological Facies Models with Fidelity to Diversity and Statistics of Training Images using Improved Generative Adversarial Networks [PDF]

open access: yesarXiv, 2019
This paper presents a methodology and workflow that overcome the limitations of the conventional Generative Adversarial Networks (GANs) for geological facies modeling. It attempts to improve the training stability and guarantee the diversity of the generated geology through interpretable latent vectors.

New insights into one of the oldest glacial deposits in the northern Alpine foreland (Höchsten, SW Germany)

open access: yesBoreas, EarlyView.
Diamictic deposits within a presumed Early Pleistocene overdeepened basin are investigated with a combined sedimentological‐geotechnical approach including analysis via μCT scans. Sedimentary facies, geotechnical properties, and microstructures reflect a transition from glacier‐proximal deposition towards direct ice contact and subglacial deformation ...

AdaSemSeg: An Adaptive Few-shot Semantic Segmentation of Seismic Facies [PDF]

open access: yesarXiv
Automated interpretation of seismic images using deep learning methods is challenging because of the limited availability of training data. Few-shot learning is a suitable learning paradigm in such scenarios due to its ability to adapt to a new task with limited supervision (small training budget). Existing few-shot semantic segmentation (FSSS) methods

De Geer moraine internal architecture based on sedimentological and geophysical investigations and implications for ice‐marginal reconstructions

open access: yesBoreas, EarlyView.
De Geer moraines may act as valuable ice‐marginal indicators; however, to date, their variable mode of formation has presented challenges for this utility. Here, we present sedimentological and ground penetrating radar data of DGMs located in southwest Finland.

Early diagnosis of the urofacial syndrome is essential to prevent irreversible renal failure

open access: yesInternational Brazilian Journal of Urology, 2005
INTRODUCTION: The urofacial or Ochoa syndrome is a rare disease characterized by the presence of functional obstructive uropathy associated with peculiar facial features when patients attempt to smile or laugh.
