Detection of Sedimentary Basins and Karstic Faults in the Yucatán Peninsula by Gravity Inversion and Euler Deconvolution

Earth
The northern Yucatán Peninsula hosts a complex karstic environment shaped by carbonate platform development and the Chicxulub impact event, making subsurface characterization crucial for geological and hydrogeological studies.

Spatial and temporal control of the volcanic activities over the distribution of sediments in the Magadi basin, Kenya Rift

Scientific African, 2023
High-velocity layers in basins with significant sub-basalt coverage, such as the Magadi basin, can impede geophysical imaging of potential subsurface hydrocarbon deposits.

MIDAS: a methodological framework for high‐speed high‐energy diffraction microscopy data reduction. Part I: methodology

Acta Crystallographica Section A, Volume 82, Issue 4, Page 242-255, July 2026.
This paper details the complete methodological framework implemented in the MIDAS software for processing high‐energy diffraction microscopy (HEDM) data. We describe the specific algorithms, coordinate systems and physical models used for both far‐field and near‐field HEDM analysis.

Applying the regularized derivatives approach in Euler deconvolution and modeling geophysical data to estimate the deep active structures for the northern Red Sea Rift region, Egypt

Contributions to Geophysics and Geodesy, 2012
The Red Sea is considered to be a typical example of a newly formed ocean. Moreover the northern Red Sea region and Gulf of Suez are generally important due to their hydrocarbon resources. Estimation of higher derivatives of potential fields represents a

Araguainha Dome, Brazil: A polygonal impact structure due to a complex pre‐impact regional structural framework

Meteoritics &Planetary Science, Volume 61, Issue 7, Page 1355-1385, July 2026.
Abstract We investigated the structural framework of the north–northwestern Paraná Basin in Brazil to test whether the pre‐impact structures in this region may have had any influence on the first‐order formation and morphostructure of the Araguainha impact structure (AIS).

3D Simultaneous Inversion and Modeling of Full Tensor Gravity and Gravity Data for Salt Imaging

Geosciences
In this study, we performed three-dimensional gravity modeling and inversion of the Vinton Dome, a well-known onshore salt structure located in southwestern Louisiana, USA, by simultaneously integrating Full Tensor Gravity (FTG) and conventional gravity ...

Vulnerability of the locus coeruleus–entorhinal cortex white matter tract in autosomal dominant Alzheimer's disease

Alzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract INTRODUCTION Locus coeruleus (LC) structural integrity declines early in sporadic and autosomal dominant Alzheimer's disease (AD). We examined LC–entorhinal cortex (LC‐EC) tract integrity and its association with amyloid and tau pathology and memory in autosomal dominant AD (ADAD).

The Impact of Topological and Graphical Choices on the Perception of Euler Diagrams [PDF]

, 2015
This paper establishes the impact of topological and graphical properties on the comprehension of Euler diagrams. To-date, various studies have examined the impact of individual properties of Euler diagrams, such as curve shape and orientation.

Basement Configuration and Tectonic Evolution Beneath Zallah Trough, Western Sirt Basin, Libya, Obtained from Integrated Gravity, and Aeromagnetic Data

Iraqi Geological Journal
In this study, gravity and aeromagnetic datasets are analysed to map fault systems and the depth of the basement, which has hitherto been unknown. The gravity and magnetic data were provided by the Libyan Petroleum Institute.

The Importance of Sample‐to‐Sensor Distance in Quantitative Micro(Paleo‐)Magnetic Analysis

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Information on the past of Earth's magnetic field can be retrieved from magnetic grains in rock samples. Micromagnetic Tomography (MMT) is a recently developed method that uses magnetic surface scans from a Quantum Diamond Microscope (QDM) combined with the position of magnetic grains in rock samples to calculate the magnetic moments of those ...
