Marquez crater is a meteorite crater located in Leon County, Texas near the small town of Marquez about 177 km (110 mi) northeast of Austin, Texas, United States.[1]
It is 12.7 km (8 mi) in diameter and the age is estimated to be 58 ± 2 million years (
central peak rising at least 1,120 m (3,670 ft) above the base of the buried crater.[3] The uplift was initially thought to indicate an underlying salt dome by early investigators, but this origin was ruled out by reflection seismology and the discovery of features like shatter cones strongly associated with meteoric origin.[4]
