The visited area is located near the town Geraldton (Western Australia). The Gravity Anomaly Map indicates that Ejecta-material either from the assumed Ø400x350km Port Hedland Crater or from the Victoria-Lake Crater (E-Africa) in all probability impacted here and formed these linear structures. The Port Hedland Crater is located north of the town Port Hedland on the sea-floor of the Indian Ocean. The Port Hedland Crater and the Victoria-Lake Crater (VLC), which are both unknown craters yet, in all probability are large secondary craters that were caused by the Permian-Triassic Impact Event (PTI). The geological map shows large-scale structures that have strong similarities to structures caused by ejecta-blankets which were produced by an impact. These structures consist of rock types that are different to the rock types of the surrounding plains of the Yilgarn-Craton. The nearly linear ejecta-ray structures seem to have penetrated the Yilgarn-Craton approximately up to a depth of around 10km (see geologic cross-section B-C). I have collected some rock-samples from these nearly linear structures in the Geraldton-area and have analysed these samples, mostly quartz, with Micro-Raman-Spectroscopy, to find out if they were exposed to a shock-pressure which may indicate an Impact Event. And indeed that is the case ! The Raman-spectra of quartz from the Sample Sites 11, 12 and 17 provide first evidence for an impact event as the probable cause of the linear ray-structure in the visited area. Indication for an impact shock event comes also from the sites 23 and 24. The clear shifts of the main Raman peaks, of the analysed quartz samples, to the lower frequencies 461 and 126 cm-1 (Site 11, stone 2), to 463, 262/268 and 125 cm-1 (Site 17, stone 1), to 463 and 125 cm-1 (Site 11, stone 1), to 260/265, 125 cm-1 (Site 17, stone 2) and to 261 and 126 cm-1 (Site 12) provide first proof for an Impact Event as the cause of the ray-structure visible on a gravity-anomaly- and on a geological map ! Microscopic images of some analysed quartz grains seem to provide further proof for a shock event. PDFs (planar deformation features) seem to be present in some samples (see images on pages 3 to 14). All spectra were made with a BRUKER Senterra-II Raman-Microscope. Images of the analysed rock samples and photos of the sample sites are in the Appendix at page 21.
