This is a summary of the Raman-spectroscopic analysis a of rock-samples which I have collected near the Ø 20 x 15 km “Tejeda Impact Crater“ on Gran Canaria, and on other interesting sites on the Island. Some of the analysed feldspar-samples may show Raman-spectra which indicate (W)-weakly-shocked or (M)-moderately-shocked Feldspar. The Raman-spectra from the following sample sites No.: 15-A, 23, 28, 32 & 33 may indicate shocked feldspar-minerals. These Raman-spectra must be further analysed by experts with the experience to correctly assess such spectra. ( explanation to Raman-spectra of shocked Feldspar : see at page 30 in the Appendix 3 ) Beside possible shocked feldspar minerals other minerals, e.g. a number of iron-bearer-minerals found on the island, may also indicate an impact event. Different types of feldspar-breccia on sample site 32 and 34-B (on the west-coast), and rock-samples from the tip of the outflow-tongue from the Tejeda Crater, which contain iron-bearer minerals like Magnetite may provide the evidence for an impact event. Minerals found in the analyses : Albite, Anorthoclase, Augite, Corvusite, Coyoteite, Cronstedtite, Hollandite, Labradorite, Magnetite, Microcline, Oligoclase, Orthoclase, Tengerite, etc. According to my hypothesis the hot spots which caused the Canary Islands originally were impact sites of large ejecta fragments, which were ejected from the Permian Triassic Impact Crater in the Arctic Sea. And I am sure that these impact sites (hotspots) were produced by the same large-scale secondary impact event (caused by the PTI), which also has formed the "Bay of Lyon Crater" and other secondary-impact-structures in Spain. This large-scale impact event is visible on the Gravity-Anomaly Map of the Canarian Islands. The PT-Impact Event probably formed a large secondary-crater, the hypothetical Ø430x290km Gibraltar-Crater (GIC) (see gravity anomaly map). The smaller oblique (ellipitical) impact-craters indicated on this Gravity-Anomaly-map, offshore of Fuerteventura, Lanzarote and Tenerife, all belong to this impact-event and are located along the hypothetical crater-wall (-rim) of the GIC. A magnetic-anomaly-map of the Atlantic-Ocean-floor south-west of Spain provides indication for this Ø430x290km Gibraltar Crater.
