 The Ø 420 km Southern Ocean Crater : Evidence of another ejecta ray structure south of Kalgoorlie  ► the Ejecta-ray-structure was caused by the ø 420km crater ! 

 The geological map of the area south of Kalgoorlie already indicates a suspious linar geological structure, the FRASER RANGE.

 Rock samples from the center line of the mountain range show large amounts of mineral glass   

 (diaplectic glass) which is a strong indicator for an impact origin. 

 Further indication gives a map combination of a gravity anomaly map of Australia and a topographic map of Antartica, arranged to each other so as they were ~200 Ma ago ( at Pangea time ).

 The image indicates a  420 km crater !! from which the large ejecta ray

 ( the Fraser Range ) seems to be ejected from !!

      Note the ring structures, the strong ejecta ray and the cone shaped

      gravity anomaly which has it’s apex in the center of the red marked

      impact crater.    And there seems to be another large crater !!
