Yes, I think you probably recognize that sort of rock.

Maybe not this one, but I'm sure others could...

I scanned it with the Zeiss Axioscan thinsections scanner. At the lowest resolution, that took just a few minutes.

Sure! A carbonated serpentinite from Feragen, Norway.
We published an overview of the many types of carbonation in that area a while ago: njg.geologi.no/publications...
I still do not entirely understand these rocks, but at some point I had put so much work into this that it had to be published. :D

Ophicarbonates of the Feragen Ultramafic Body, central Norway - Norwegian Journal of Geology
The carbonation of ultramafic rocks is a common alteration process in ophiolites and can occur in various settings. We provide the first detailed description of the carbonated peridotites (ophicarbonates) of the Feragen Ultramafic Body, central Norway, which have unusually variable compositions and microstructures. Lithologies range from pervasively carbonated serpentinites through carbonated serpentinite breccias to carbonated […]

Imaggeo on Mondays: The Grid – A serpentine pseudomorph after carbonate
The structures in this photo might look three-dimensional, but they are completely flat. It is a photo of a polished thinsection of a rock, taken through a petrographic microscope under cross-polarize...
