The outcrops here look to have the right sort of dip to be intact everted rim strata from the Endeavour impact. (Such were in short supply at Cape York, perhaps because it suffered more slumping, immediately post-impact or subsequently, than the Solander/Tribulation rim segment.) Of course I'm actively looking for everted strata, so maybe I'm seeing them where there aren't any. What do others think? http://qt.exploratorium.edu/mars/opportuni...OXP2364R1M1.JPG

The outcrops here look to have the right sort of dip to be intact everted rim strata from the Endeavour impact.......... The rim is extremely eroded and part of the remnant could well be upturned or overturned elements of the original impact rim. But Endeavour was formed in the deep Miyamoto ejecta blanket so it would be difficult to differentiate between brecciated breccia from the Endeavour impact and original Miyamoto breccia in an upturned rim. Stratification is normally accepted to be sedimentary so if pre-Endeavour strata was identified this would provide some really interesting indications of the history of the area post Miyamoto and prior to Endeavour. |
