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.

Revisiting the Hummeln structure, Sweden—A shallow marine Cambrian impact structure
Abstract Hummeln is a simple impact structure located in south‐eastern Sweden. It is approximately 1.2 km in diameter and almost completely covered by a lake. Here, we present the first detailed investigation of impactites and mapping of the 164.25 m deep drill core Hummeln‐1 with a focus on impact metamorphism and the impact process.
