![]() The red box indicates the area of today's featured NAC frame. Unraveling the origin of lunar features like this one is a primary focus of LROC science.ġ00 m/px WAC context image of Atlas crater. When investigating floor-fractured craters, geologists often look for signs of volcanic activity related to an intrusion of magma. Atlas Fractures: Diagnosis, Current Treatment Recommendations, and Implications for Elderly Patients Authors Richard M Smith 1, Amit K Bhandutia 2, Julio J Jauregui 2, Mark Shasti 2, Steven C Ludwig 2 Affiliations 1 Drexel University College of Medicine, Philadelphia, PA. A second possibility is that the fractures may be due to an intrusion of magma into the crust below the crater, which uplifted and disrupted the crater floor as it rose. Seven break gel premier, Death sasha wilson, Ascot to reading taxi, Collectionitem. This rebound would supply the uplift that forms the fractures on the floor of Atlas crater. ![]() However, over time the crust can rebound to its original, pre-impact position. During an impact, the energy released compresses the crust. One possibility is the slow readjustment of the crust after the crater-forming impact. There are two theories for the cause of the uplift. type 1: isolated posterior arch fracture. Gehweiler classification of atlas fractures 6. Fractured Atlas will therefore ensure that. This commitment is grounded in our belief that change is possible, and that our work and that of the artistic community as a whole will grow stronger as oppression is eliminated. In the case of Atlas, eventually uplift caused the floor to break and pull apart, forming the graben, or fractures. Atlas was the name of the Classical Greek god who bore the world on his shoulders 3. We are committed to anti-oppression principles in all areas of our internal and external work. LROC NAC frames allow for a look at the interiors of the fractures, and with stereo images we can measure their shapes.Īfter the impact that created Atlas, the floor of the crater was molten. The question is, what caused the uplift? Floor-fractured craters have been a known lunar feature since the days of the Lunar Orbiters, but with LROC images, geologists are working to better understand how they formed. It is thought that the fractures have wide, flat floors, like a trough (or graben) and that they record a period of uplift of the crater floor. The cause of the fractures that cut the crater's floor is not well understood. ![]() The floor-fractured Atlas crater, located at 46.7°N, 44.4☎, is 87 km in diameter. Image number M157303976L, incidence angle 47°, image scale 0.5 m/pixels. Atlas Fractures & Transverse Ligament Injuries are traumatic injuries usually caused by high-energy trauma with axial loading in young patients (Jefferson Fracture) or low-energy falls in elderly. The interior of a crater-floor fracture within Atlas crater. ![]()
