A major tool in the initial recognition and study of terrestrial impact craters,∼ 20% of which
are buried beneath postimpact sediments, is geophysics. The general geophysical character …

The Chicxulub crater is an∼ 180‐km‐diameter peak‐ring crater based on drill hole logs and
samples, potential fields, seismic reflection profiles, and surface fracture patterns. A …

Meteorite impact craters are one of the most common geological features in the solar
system. An impact event is a near-instantaneous process that releases a huge amount of …

ABSTRACT The 200 Ma, 24-km-diameter Rochechouart impact structure was formed in
granitic intrusive and metamorphic rocks of Variscan age (400–300 Ma) close to the margin …

Age determination of impact structures via the zircon U-Pb system remains challenging and
often ambiguous due to highly variable effects of shock metamorphism on U-Pb …

A progress report on geophysical and geological investigations in the 35–40 km diameter
Azuara probable impact structure (northeast Spain) is given. The target is a 10 km thick …

Fracture pattern, pseudotachylite veins and breccia dikes were studied in the basement
rocks of the Rochechouart structure to clarify their genetic relationship to the impact event …

The gravity survey of the Steinheim impact crater comprises about 500 gravity stations
resulting in a Bouguer anomaly map of the crater and its surroundings. From this map a …

The Rochechouart impact structure, south‐central France (45o50′ N, 0o46′ E), is a partly
eroded, approximately 200 Myr, complex impact structure. The impactite suite at …

The Rochechouart impact structure in the northwestern part of the French Massif Central
(FMC) has a great diversity of impactites, including monomict impact breccias, suevite, and …
