Thickness of Fluvial Deposits Records Climate Oscillations
(
- Journal of Geophysical Research: Solid Earth
, 2022-04-08)
Fluvial deposits offer Earth’s best‐preserved geomorphic record of past climate change over geological timescales. However, quantitatively extracting this information remains challenging in part due to the complexity of ...
Plate corner subduction and rapid localized exhumation: Insights from 3D coupled geodynamic and geomorphological modelling
(
- Terra Nova
, 2022-02-25)
Rapid, localized exhumation has been reported at many plate corners between adjacent subduction/collision segments. Here we use a fully‐coupled geodynamic and geomorphological modelling approach to investigate overriding ...
Constraining Andean Propagation of Exhumation at the Limit of the Eastern Cordillera, NW Argentina, Using Low‐Temperature Thermochronology in a Structural Context
(
- Tectonics
, 2022-08-16)
Within the Central Andes of NW Argentina, the spatiotemporal distribution and style of deformation is strongly influenced by pre‐Cenozoic heterogeneities, mostly related to the Salta rift extension in the Cretaceous. At ...
Stochastic Modeling Approach to Identify Uncertainties of Karst Conduit Networks in Carbonate Aquifers
(
- Water Resources Research
, 2022-08-09)
The characterization of the karst conduit network is an essential task to understand the complex flow system within karst aquifers. However, this task is challenging and often associated with uncertainty. Equivalent porous ...
Spontaneously Exsolved Free Gas During Major Storms as an Ephemeral Gas Source for Pockmark Formation
(
- Geochemistry, Geophysics, Geosystems
, 2022-08-12)
Abrupt fluid emissions from shallow marine sediments pose a threat to seafloor installations like wind farms and offshore cables. Quantifying such fluid emissions and linking pockmarks, the seafloor manifestations of fluid ...
Cyclostratigraphy and paleoenvironmental inference from downhole logging of sediments in tropical Lake Towuti, Indonesia
(
- Journal of Paleolimnology
, 2021-02-12)
Lake Towuti is located on central Sulawesi/Indonesia, within the Indo Pacific Warm Pool, a globally important region for atmospheric heat and moisture budgets. In 2015 the Towuti Drilling Project recovered more than 1000 m ...
Early Eocene magnetostratigraphy and tectonic evolution of the Xining Basin, NE Tibet
(
- Basin Research
, 2022-10-12)
The Cenozoic strata of the Xining Basin, NE Tibet, have provided crucial records for understanding the tectonic and palaeo‐environmental evolution of the region. Yet, the age of the lower part of the sedimentary stratigraphy ...
Combining implicit geological modeling, field surveys, and hydrogeological modeling to describe groundwater flow in a karst aquifer
(
- Hydrogeology Journal
, 2020-09-15)
Abstract
In three-dimensional (3-D) implicit geological modeling, the bounding surfaces between geological units are automatically constructed from lithological contact data (position and orientation) and the ...
Assessment of the heterogeneity of hydraulic properties in gravelly outwash plains: a regionally scaled sedimentological analysis in the Munich gravel plain, Germany
(
- Hydrogeology Journal
, 2020-08-11)
The favorable overall conditions for the utilization of groundwater in fluvioglacial aquifers are impacted by significant heterogeneity in the hydraulic conductivity, which is related to small-scale facies changes. Knowledge ...
Ensemble-based stochastic permeability and flow simulation of a sparsely sampled hard-rock aquifer supported by high performance computing
(
- Hydrogeology Journal
, 2020-05-07)
Calibrating the heterogeneous permeability distribution of hard-rock aquifers based on sparse data is challenging but crucial for obtaining meaningful groundwater flow models. This study demonstrates the applicability of ...
