WitrynaNamed after the town of Rochechouart, the Rochechouart impact structure is located on the western margin of the French Massif Central near the city of Limoges, approximately 350 km (220 mi) south of Paris. Rochechouart (population about 3800) is built with rocks created or modified by the impact (impactites). east jefferson property transfers aug 2022Impactite is rock created or modified by one or more impacts of a meteorite. Impactites are considered metamorphic rock, because their source materials were modified by the heat and pressure of the impact. On Earth, impactites consist primarily of modified terrestrial material, sometimes with … Zobacz więcej When a large meteorite hits a planet, it can radically deform the rocks and regolith that it hits.
