The 1270x950km Permian-Triassic Impact-Crater_summary of the Geophysical Evidence

This is a summary of geophysical evidence for the O1270x950 km Permian-Triassic (PT)-Impact-Crater which I have discovered and described in my hypothesis Part 1-6. A topographic map and a satellite image of the Arctic Ocean area, Alaska and Siberia provided the first indication for the PT-Impact Crater and –impact event. The similarities of structures visible on the topographic map to the structures calculated by a computer simulation of a shallow (oblique) impact with an impact angle of 5°, provide a strong indication for the existence of the O1270x950 km PT-Impact-Crater on the Arctic Ocean floor. Especially the elliptical deep sea basin in the Arctic Ocean, the bow-shaped Brooks Range in Alaska and the northern edge of the Central Siberian Plateau (Siberian Traps), which has the same bow-wave-structure like the calculated structure, are strong indicators that the PT-Impact Crater was caused by a shallow impact of an asteroid or comet. Further strong indication for the PT-Impact-Crater comes from a gravity anomaly map and from a magnetic anomaly map of the Arctic Ocean area and Alaska. The gravity anomaly map clearly shows sections of the elliptical crater-wall of the PT-Impact Crater (positive anomalies) . The Brooks Range in Alaska, which originally was part of the elliptical crater-wall-structure, is also indicated by a positive anomaly on the map. This section drifted away from the PT-Crater, caused by forces of the massive amount of ejecta material that was ejected from the crater, which probably was in the range of 100.000.000 to 200.000.000 km^3 of ejecta-material ! The magnetic anomaly map of the Arctic Ocean area shows a triangular-shaped positive anomaly (red), which originates in the crater center. This indicates ejecta that was coming from an iron-rich impactor. The big distance between the elliptical impact basin and the described bow-wave-shaped structure in Siberia, which originally was located directly at the front-end of the PT-Crater, is the result of a divergent tectonic motion and expansion tectonics process that was triggered by the shallow PT-impact. The leading edges (front edges) of the two gigantic ejecta wings which were caused by the PT-Impact, cut through Earth’s crust and large amounts of impactor material (e.g. iron) and ejecta material descended into Earth’s mantle and caused the Pacific-LLSVP and the African-LLSVP. All volcanos of the Pacific Fire Ring and volcanism on Earth can be explained solely by the PT-Impact !
