Sahoui R. Belhai D. Tin Bider Crater (Algeria): New Field Data and Metamorphism Shock [#6061] Tin Bider Crater The Tin Bider Crater in the Algerian part of the Sahara Desert dominates the local area. A meteorite impact structure of Tin Bider shows, In addition the classical markers of impacts, superposed structures. The crater rises above the surrounding terrain, however the position of the sun makes it appear to be below it. Where the Tin Bider crater lies!

The crater is exposed to the surface. In the image on the left of the Tin Bider crater produced by NASA Earth Observatory's EO-1-based Advanced Land Imager produces a reverse illusion. It consists of different layers of rock, whose erosion as varied greatly over time. We realized a geological map including new inputs on impact characters of a recent field investigation where we identify shatter cone and folds. Tin Bider is a 6 km diameter crater emplaced on a sedimentary mixed target rock including sandstones, limestones, shales, gypsum...It is formed by a central pick and two circular rings; where shock effects are defined, as to kinds of breccias. It has a complicated terraced structure, indicating that the rock inside may have slumped after impact -- a … The other streaks near the crater are unrelated to the impact … See more ideas about Rocks and minerals, Iron meteorite and Rocks and gems. Tin Bider Crater is an impact crater (astrobleme) in Algeria. Those are manifested by folds with perpendicular axes which are linked to two different phases during the impact event. The angle of sunlight is from the south, and Tin Bider actually rises above the land to the south, east, and west.

The Tin Bider Crater is referred to as a complex crater that was created millions of years ago, and is a fascinating site that has been studied by geologists.

This three-dimensional terrain model has been calculated using data from the German Aerospace Center (DLR) satellites TerraSAR-X and TanDEM-X. Geologists suspect that Tin Bider is an impact crater and estimate that it was formed in the past 70 million years, perhaps in the late Cretaceous or early Tertiary Period. The most interesting feature of the crater is that it is very deceiving when looked at, as it seems to be located at a lower elevation when compared to its surroundings, but when taking a closer look, one realizes that it isn’t. It consists of different layers of rock, whose erosion as varied greatly over time. Some span a mere 10 metres, while others extend across 160 kilometres and are significantly more impressive. Those are manifested by folds with perpendicular axes which are linked to two different phases during the impact event. 2011 NASA Earth Observatory image of Tin Bider Crater rotated.jpg 2,500 × 2,500; 1.44 MB The Tin Bider Crater in the Algerian part of the Sahara Desert dominates the local area. Crater of Tin Bider which allows to sequence the evolution of the deformations during th e episode of craterization. A meteorite impact structure of Tin Bider shows, In addition the classical markers of impacts, superposed structures. Tin Bider is an ancient and eroded meteor crater on the Tin Rhert Plateau in the Algerian Sahara. There are just 188 known meteorite craters worldwide. The Barringer Medal and Award were established in 1982 to honor the memory of D. Moreau Barringer Sr. and his son D. Moreau Barringer Jr. and are sponsored by the Barringer Crater Company.
