Abstract

The large 840 x 630 km elliptical Pantanal Crater is easy visible on a Lithosphere-Thickness Map of South-America. A topographic map clearly shows a remaining crater-wall section of this gigantic impact crater. Further indication for the assumed impact crater can be found on a magnetic anomaly map of South America. The impact side is indicated by a red-colored flame-like feature on this map, which indicates the outflow of large amounts of magma from the original crater center. The Central Atlantic Magmatic Province (CAMP) may be the result of the Pantanal Impact. Because this flame-like feature appears two times on the magnetic anomaly map, the crater area probably was tectonically shifted away from the original impact side in the east, which then produced another outflow at a later time. The Pantanal Impact caused a large crack, visible on the Lithosphere-Thickness Map. Three other large Craters are visible on the different maps. These three craters are in the O 200-400 km diameter range. The large craters found on different maps of South-America in all probability are Secondary- Impact Craters which were caused by Ejecta Material from the Permian-Triassic (PT) Impact Event. During the Permian Triassic (PT)-Impact Event which formed the 1270 x 950 km elliptical PT-Impact Crater a large amount of rock-material was excavated from Earth’s crust. The impactor which caused the PT-Impact, was an asteroid or comet in the diameter range of probably 60 to 200 km, which collided with our planet at a very shallow angle of probably less than 8°. Because of its enormous size, the Pantanal Crater may be the result of a large fragment of the PT-Impactor in the diameter range of 30-60 km which either was ejected from the PT-Crater, or which broke-off from the main impactor and travelled a bit further before it impacted in South-America.
