Less than ten thousand years old, and with a diameter of 100 m (330 ft) or more. The EID lists fewer than ten such craters, and the largest in the last 100,000 years (100 ka) is the 4.5 km (2.8 mi) Rio Cuarto crater in Argentina. [2]
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 ( Paleocene ).
This list includes all 60 confirmed impact structures in North America in the Earth Impact Database (EID). These features were caused by the collision of large meteorites or comets with the Earth. For eroded or buried craters, the stated diameter typically refers to an estimate of original rim diameter, and may not correspond to present surface ...
This is one of three impact crater sites found in Texas, the others being the older and much larger Sierra Madera crater and the Marquez crater. The Handbook of Texas Online describes the Odessa meteor crater as the largest of several smaller craters in the immediate area that were formed by the impact of thousands of octahedrites (an iron ...
If the team can determine the site is a crater formed by an ancient impact event, then the next step is researching just when it happened. Of the world’s roughly 200 impact craters, 31 are ...
As the trend in the Earth Impact Database for about 26 confirmed craters younger than a million years old shows that almost all are less than two km (1.2 mi) in diameter (except the three km (1.9 mi) Agoudal and four km (2.5 mi) Rio Cuarto), the suggestion that two large craters, Mahuika (20 km (12 mi)) and Burckle (30 km (19 mi)), formed only ...
This is maybe just a tiny bit morbid but also cool science: A team of geologists and Earth scientists have figured out a new way to identify ancient impact craters: By the way they burned ...
The Sierra Madera crater is a meteorite crater in southwestern Pecos County, Texas, United States. [1] The central peak of the rebound structure of the impact crater rises 793 ft (242 m) above the surrounding land. [3] The peak is visible from U.S. Highway 385 between Fort Stockton, Texas and Marathon, Texas. The Sierra Madera crater is located ...
