Abstract
I will first give an overview of the Permian Triassic (PT) Impact Event on the first pages before I describe the Secondary-Craters and -Impact Structures of the PT-Impact. The section which describes the assumed secondary craters and impact structures in Europe, Africa & Australia that were caused by the PT-Impact Event starts at page 12. The large secondary- impact craters and –structures found in Australia, Europe and Africa were caused by Ejecta Material that was produced during the Permian Triassic (PT)-Impact Event in the Artic Sea which formed the 1270 x 950 km elliptical PT-Impact Crater. The impactor which caused the PT-Impact, an asteroid or comet in the diameter range of probably 60 to 200 km, collided with our planet at a very shallow angle. Because of this very shallow impact angle of probably less than 8° and the estimated low impact velocity of around 8 km/s, large amounts of material was excavated from Earth’s crust during the impact. This excavated crust material, together with large fragments of the impactor, is the ejecta material that caused many large secondary craters & impact structures on Earth. It probably had a velocity of slightly less than 8 km/s. Some large fragments of the impactor or of the ejected material caused a secondary impact crater chain along the NE-coast of Australia. An exceptional large impact crater of this crater-chain, the > 300 km Cape York Crater caused a number of large-scale magma eruptions over a long time period, which were partly responsible for the creation of the Pacific Plate as described in more detail in Part 1 of my study. In Europe and Africa powerful Ejecta Rays from the PT-Impact Event caused further secondary impact crater chains with crater diameters of up to 200 km. The tracks of these crater chains are clearly visible on different gravity anomaly maps, which show the reduced thickness of Earth’s crust in these areas ( blue areas ). It is clearly visible that these tracks of the Ejecta Rays intersect at a certain point which was the impact location of the PT-Impact at the time of impact, in the North of Siberia. The outline of Italy is a direct result of these crater chains as my drawings indicate. [Truncated by viXra Admin to < 400 words]
