This is a supplement document to my Summary of geophysical evidence for the Ø1270x950km Permian-Triassic (PT)-Impact-Crater (see Part 6 of my hypothesis).The purpose of this document is to point-out the main geo-physical features visible on our planet Earth, that were directly caused by the Permian-Triassic Impact-Event.A comparison of the real PT-Crater-topography with a computer-simulated-topography indicates a Probability >99,99997% for the real existence of the PT-Crater ! Further I want to inform about two other possible impact-structures on Earth, which I believe are a result of the global PT-Impact Event too. The first structure seems to be a "smaller-twin" of the PT-Impact Crater. It is the Tarim Basin in NW-China. The Kunlun Mountains around it indicate an age of 250 Ma !The Tarim-Basin has an approximate elliptical shape with the dimensions of ≈900x400km (see page 7-8). This basin probably was formed by a second impactor that impacted in-line with the main-impactor which has caused the PT-Impact-Crater. The 900x400km elliptical Tarim-Basin probably had a shorter elliptical outline of around 750x500km shortly after the PT-Impact, but was then deformed later.If we use a double-oblique elliptical impact-crater-twin on Mars as a reference, then the Tarim-Basin-Impact was caused by a similar effect as the smaller oblique impact crater of the Mars-Impact, which is located in-line with the bigger oblique-impact-crater but a bit uprange (ahead) of the main-impact-crater.In the NASA-study about this double-oblique impact on Mars, as reason for this double-impact, the probable collapse (break-up into pieces) of the impactor shortly before the impact was mentioned. This collapse of the impactor just before the impact in all probability was caused by atmospheric effects (e.g. by the atmospheric impact-shock-wave which hit the impactor, and atmospheric-drag etc.). Initial cracks inside the impactor probably already occurred when the impactor reached the "Roche-limit" of Mars (the point where gravitational forces start to rip the impactor apart). The other possible impact-structure which I want to describe is the 41x32km elliptical shaped F’derik Zouerate district Iron-ore-mine in Mauretania (NW-Africa). see page 9. It is located in a dark-colored-area which contains Fe-rich minerals. This iron-rich area has an outline which can be fit precisely into an ellipse ! That‘s why I believe that this iron-rich-area is the result of a secondary- or tertiary-impact in the PT-Ejecta Ray R1, which was caused by the PT-Impact Event and which runs along the NW-coast of Africa.
