Glaciovolcanism at Volcán Sollipulli, southern Chile: lithofacies analysis and interpretation [PDF]

open access: yes, 2015
Magma–ice–meltwater interactions produce diverse landforms and lithofacies, reflecting the multitude of factors that influence glaciovolcanism, including both magmatic (e.g., composition, eruption rate) and glacial (e.g., ice thickness, thermal regime ...

Cross‐Dimensional Generative Adversarial Networks (CDGAN) Geomodeling: Bridging 2D Geological Figures and 3D Reservoir Modeling

open access: yesWater Resources Research, Volume 62, Issue 6, June 2026.
Abstract Generative adversarial networks (GANs) have proven effective in simulating complex reservoir environments, such as meandering channels and deltas. In classic GANs, the dimensionality of training data determines that of generated data: a 2D (or 3D) reservoir facies simulator (generator) requires training with corresponding 2D (or 3D) data sets.

Disentangling palaeoecological and outcrop controls on MISS occurrence in c. 1 Ga fluvio‐lacustrine facies of the Diabaig Formation, Scotland

open access: yesSedimentology, Volume 73, Issue 4, Page 883-913, June 2026.
ABSTRACT The c. 1 Ga Diabaig Formation of north‐west Scotland preserves diverse lacustrine and fluvial facies and abundant microbial and non‐microbial surficial sedimentary features. 172.6 m of section was logged across seven localities to assess the distribution of microbially induced sedimentary structures (MISS) relative to lithofacies, substrate ...

Lithofacies module methodology for characterizing and modeling clastic hydrocarbon reservoirs. [PDF]

open access: yes, 1997
The geological framework and concept used in building the reservoir model determine the distribution of reservoir properties that control fluid flow. Reservoir simulation studies at the Gypsy outcrop site show different concepts for defining a reservoir ...

Lithofacies Determination in the Willesden Green and South Pembina Duvernay Formation: Creation, Characterization, and Correlation

open access: yes, 2018
This study proposes a set of lithofacies in the Southern West Shale Basin of the Duvernay Formation that characterize variation at core and thin section scales, correlate with conventional well logs and can be further related to geochemical data, elastic

Modular artificial neural network for prediction of petrophysical properties from well log data

open access: yes, 1996
This paper reports the application of Kohonen's Self-Organizing Map (SOM) and Learning Vector Quantization (LVQ) algorithms, and the commonly used Back Propagation Neural Network (BPNN) to the prediction of petrophysical properties from well log data ...

VOLCANIC-DEBRIS-AVALANCHE DEPOSITS IN NEW ZEALAND—LITHOFACIES ORGANIZATION IN UNCONFINED, WET-AVALANCHE FLOWS

open access: yes, 1991
The lithofacies represent division of the debris-avalanche deposits into megaclast-rich (axial-A) and interclast matrix-rich (axial-B) parts and transformation of the avalanches into lahars (marginal lithofacies).

Stratigraphy and reserves of pumiceous sand deposits in Perry's 'Asparagus Block' at Horotiu

open access: yes, 1997
The stratigraphic relationships between the deposits of the Hinuera Formation and the Taupo Pumice Alluvium are described over a 16 ha plot of land known as the 'Asparagus Block' at Horotiu. The Hinuera Formation is exposed at the surface at the southern
