Hello Walter, and list
You can have both situation, but generally it "infects" more the inside throught weathering cracks than replace the outside fusion crust.
Look at www.caillou-noir.com/Caliche.htm I have 2 example of caliche.

Hello Everyone,
Speaking of Caliche...
Does the Caliche (form of calcium carbonate) that we sometimes see on desert
meteorites replace the fusion crust that is present or does it form a layer
over the crust?
