1.9km wide and with a 100m high rim, the best estimates for the age of Tenoumer Crater place it between 10,000–30,000 years old. That’s relatively short in the history of of impact craters on earth! How to visit Tenoumer Crater: Tenoumer Crater is in the desert, so you’ll need to strike out on your own to reach it. Even more recent is our realization that, over the history of Earth, these impacts have had an important influence on the evolution of life. Figure 8.5.1 8.5. 1 Ouarkziz Impact Crater. Located in Algeria, this crater (the round feature in the center) is the result of a meteor impact during the Cretaceous period. Just like the impact craters on Earth and other terrestrial planetary bodies, impact craters on Venus include central peaks, rims, floors, walls, ejected deposits and outflows from the craters. There are two groups of materials, including undivided crater materials (c) and impact crater flow material (cf). The probable sum of these effects is the destruction of vegetation over an area 800 to 1500 km 2. Damage to vegetation would have extended over an additional 200 to 600km 2. Animals within 3 to 4 km of the impact site would probably been killed, with maiming injuries extending out to distances of ~16 to 24 km. The impact initially put a dent in Earth’s surface that spanned 60 miles wide, but the crater grew up to three times wider as its walls collapsed and the rocks below began to rebound. The Vredefort Impact Crater was formed when an asteroid struck Earth about two billion years ago in an area that is now the country of South Africa. At the time of formation, the crater is believed to have been about 300 kilometers across. Since then, the crater and its ejecta have been removed by weathering and erosion. The scope of craters as potential loci of ore deposits is going to attain increased attention in the future due to the following factors: (1) detailed exploration at known crater locations, (2) discovery of the 100+ missing craters (Kenkmann, 2021), (3) confirmation of suspected craters such as Shiva (Chatterjee et al., 2006), Bedout (Becker et The same principle applies to complex impact craters on Earth larger than ∼2 to 4 km in diameter (not shown here). (A) The ∼1.2 km-diameter and roughly 50 kyr-old Meteor Crater (aka Barringer Meteorite Crater) in Arizona is one of the best-preserved simple impact craters on Earth (e.g., Shoemaker, 1960; Kring, 2017b). Its ejecta blanket .
