The 700 km diameter Watchorn Probable Impact Structure, prima facies evidence in ELV 071 core, relationship to mineralisation, Landsat, Radiometrics, Gravity and Seismic research 1999 – 2018.
The following evidence suggests Watchorn probable impact structure is an impact structure. The morphometric dimensions of an impact structure of 700 km maximum diameter are observed in Landsat, topographic, gravity, radiometric and seismic data. Prima facies evidence of impact is seen in ELV 071 core which is located on the strong Leonora inner ring.
This paper is the culmination of nearly 50 years research of the Yilgarn by the author. It will change the fundamental way in which the geology of the Yilgarn is viewed and explored.
