Some interesting colors there. Used L3-L5-L7 for RGB. The L5 is green but L3 is somewhat infra on the red side and L7 is somewhat ultra on the violet side.

Uh-oh! Oppy, watch your step!

New micros from Oppy. Above is gamma-enhanced version to soften the shadows. Note the dark coatings with sharp boundaries.

This shows the location of the MI in the previous reply. Note the MI is upside-down (rotated through 180 degrees) relative to the pancam. Winston, it would be great if you could colorize the MI. The pancam is this one at the exploratorium site.:

Barsoomer;

I didn't read your post above carefully and made the wrong colourization.

I then tried to colourize the MI image you indicated but the colours bled into one another so my colourization is practically useless.

Sorry.

Pancam versus MI.

Thanks, Winston. That's great! Somehow your post of Oct 2 didn't show up for me until just now.

More micros of this rugged spot today.

Dark coating on bright rock? Or bright coating on dark rock?

The dark coating looks granular, like the debris flow and micro-channel material.

The grains might actually be light-colored but covered by some extremely fine dark pigment like lamp black.

Barsoomer;

Very nice 3D at reply 33.

I think it might be light deposit on dark rock. I also think the rock is composed of dark debris flow material. i.e that it might be indurated debris flow material.

I think that a case could be made that the light material may be not only a major component of fracture fills and veins but also a surficial and enclosing material that forms the fracture fills and veins as well as seemingly isolated pale covers.

Lots of CURI images could be interpreted in that way.

More from Squyres on the gully.

By the way, the ESA Schiaparelli 2016 lander is due to land in South Meridiani on October 19 (Wed week). Wonder if the descent will be visible from Oppy?

Barsoomer, re your 36, Thanks for that news item. A quote from Steve Squyres "We are confident this is a fluid carved gully, and that water was involved." Wow! I'm surprised that a feature on the present eroded surface is confidently explained as liquid water activity. Hasn't there been at least a few meters removed from the landscape by erosion since the putative ancient time in which liquid water could flow, easily enough erosion o erase that gully? Has Squyres joined the RSL proponents that see present day liquid water emerging from slopes? Everything is shifting in mainstream Mars science.

MI shows some cavities, one with polished interior, and something else...
