Geophysical investigation of the Santa Marta impact structure—Piauí State, Brazil
Abstract The Santa Marta impact structure in northeastern Brazil, recognized as a partially preserved complex crater, was investigated through an integrated geophysical study employing magnetotelluric (MT) and gravity methods. Our research provides constraints on the crater's subsurface architecture.

Abstract Among the reported seismic events on the Moon, shallow moonquakes are known for their unique features, such as high‐frequency energy excitation, similarity to intraplate earthquakes, and the largest energy release of all reported moonquakes. Despite these interesting features, a small number of samples (<80 events) and sparse seismic network ...

Estimation of CO2 Emissions in Fault Systems at a Global Scale
Abstract Influenced by tectonic, geophysical, and environmental aspects, the release of carbon dioxide (CO2) in fault systems is a fundamental component of Earth's carbon cycle. Appreciating their contribution to natural greenhouse gas flow depends on knowing these emissions.

A study of the space form of the Cornubian granite batholith and its application to detailed gravity surveys in Cornwall [PDF]
A three-dimensional computer model of the Cornubian granite batholith, defined by polygonal contours, was created so that its calculated gravity field matched the observed Bouguer Anomaly field, both onshore and offshore. The model was used to define

Abstract Lithological mapping is essential for the exploration of critical minerals supporting energy transition and national defense. Although recent advancements have incorporated multi‐source data sets and leveraged machine learning and deep learning (DL) methods, lithological mapping continues to face significant challenges, such as data imbalance,
