Bengal Bay at the center of India’s east coast was formed by an elliptical Impact Crater with the dimensions of ≈ 450 x 380 km. This is indicated by gravitational anomaly- and magnetic anomaly-maps and by satellite- and topographic-maps. The remaining NW-section of the identified Bengal Bay Impact Crater located on the Indian Plate, and the SE-section of the 400 x 350 km elliptical Port Headland Crater located on the ocean-floor in the NW of the Australian Plate probably belong to the same Impact Crater which caused a massive fracture in Earth’s crust and separated India from Australia ≈ 200-250 million years ago. The assumed trajectory of the Ø 20 to 40 km impactor, which produced this large Impact Crater, indicates that this crater in all probability is a large secondary crater which was caused by the Permian Triassic (PT) Impact Event in Siberia 253 million years ago. The impactor probably was a fragment of the asteroid or comet which caused the PT- Impact Crater. This is indicated by the iron-rich ejecta and ejecta rich in platinum-group elements that was ejected by the Bengal Bay- / Port Headland- Crater and which impacted on the Yilgarn Craton and Pilbara Craton in West-Australia, as traces on the gravity anomaly map indicate. Satellite images of India provide further evidence for this assumption. The linear western border of the Indian Plate was caused by the powerful Ejecta Ray R4 of the Permian Triassic Impact Event. Within this assumed Ejecta Ray R4 two more secondary craters of the PT-Impact Event are located. These are the two impact craters R4/8 with Ø 120 km, and the smaller Mumbai Crater with Ø 25 km ( see images on page 5 & 6 ). There is strong indication that the Iron-Ore Deposits around Sandur (India) were caused by ejecta material which was ejected by the Mumbai Impact Crater. And the impactor which formed the Mumbai Crater also seems to be a fragment of the original PT-impactor. This is indicated by the 30 km long “drop-shaped” mountain range near Sandur which contains the Sandur Iron-Ore Deposits, and by the orientation of this enormous drop-shaped ejecta-impact-structure.
