Is Geology Scaling?

open access: yesEarth and Space Science, 2019
Concept of fractals and power law in statistical and geometrical data sets is rather matured. However, the application part of the fractal theory is not yet commensurate with the theoretical literature available.

Subsurface Geological Characterization of the Late Neogene–Quaternary Argive Basin, Peloponnese, Greece Using Transient Electromagnetic Data and Vintage Stratigraphic Logs

open access: yesGeosciences, 2021
The onshore and offshore clastic deposits of the Argive Basin and the Argolic Gulf, respectively, in Peloponnese, Greece, form a Late Neogene–Quaternary half-graben that connects with the Aegean Sea.

Towards an integrated inversion of geoscientific data: What price of geology?

open access: yesTectonophysics, 2010
Abstract The inversion of multiple geoscientific datasets to define structures in hard rock terrains has for the most part been limited to geophysical methods supported by rock property constraints. In this paper we expand the range of constraints available to geological modellers by defining a series of misfit functions that are used to define the ...

Regional Responses of Vegetation Productivity to the Two Phases of ENSO

open access: yesGeophysical Research Letters
The two phases of El‐Niño‐Southern Oscillation (ENSO) influence both regional and global terrestrial vegetation productivity on inter‐annual scales.

Geophysical Subsoil Characterization and Modeling Using Cluster Analysis for Seismic Microzonation Purposes

open access: yesGeosciences, 2023
In the municipality of Enna, 80 HVSR measurements were performed, and some of these were combined with MASW seismic measurements, which made it possible to constrain the data inversion and obtain significant shear wave velocity models.

Fault Pattern and Seismotectonic Style of the Campania – Lucania 1980 Earthquake (Mw 6.9, Southern Italy): New Multidisciplinary Constraints

open access: yesFrontiers in Earth Science, 2021
New fault trace mapping and structural survey of the active faults outcropping within the epicentral area of the Campania-Lucania 1980 normal fault earthquake (Mw 6.9) are integrated with a revision of pre-existing earthquake data and with an updated ...

Processes influencing heat transfer in the near-surface ice of Greenland's ablation zone [PDF]

open access: yesThe Cryosphere, 2018
To assess the influence of various heat transfer processes on the thermal structure of near-surface ice in Greenland's ablation zone, we compare in situ measurements with thermal modeling experiments.

Research and Application of a Cross-Gradient Constrained Time-Lapse Inversion Method for Direct Current Resistivity Monitoring

open access: yesApplied Sciences
The direct current resistivity method holds advantages such as rapid, efficient, and automatic data acquisition. It is an important geophysical exploration technology for monitoring dynamic changes in subsurface geology.

Quasi-2D Resistivity Model from Inversion of Vertical Electrical Sounding (VES) Data using Guided Random Search Algorithm

open access: yesJournal of Mathematical and Fundamental Sciences, 2015
Vertical electrical sounding (VES) data are usually interpreted in terms of a 1D resistivity model using linearized inversion. The local approach of a non-linear inverse problem has fundamental limitations, i.e. the necessity of a starting model close to

Synthetic Geology: Structural Geology Meets Deep Learning

open access: yesJournal of Geophysical Research: Machine Learning and Computation
Reconstructing the structural geology and mineral composition of the first few kilometers of the Earth's subsurface from sparse or indirect surface observations remains a long‐standing challenge with critical applications in mineral exploration ...
