You got it - I think. Could also be calcium + accreted/accretion.
Same goes for "silcrete" (silica + concrete/accreted/accretion) and "ferricrete" - have a guess!

per Academic Press Dictionary of Science and Technology, no concrete is involved: calcrete Geology. 1. a conglomerate of surface sand and gravel cemented into a hard mass by calcium carbonate. 2. in a semiarid climate, a hard crust containing calcium carbonate formed on the surface of a soil. silcrete Geology. a conglomerate of surficial sand and gravel cemented together by silica. http://www.harcourt.com/dictionary

Keiva - "concretion"(n.) is a geological term - a subspherical lump of grains that have been cemented together by chemical means. Thus you are correct in saying that it has nothing to do with concrete, but concretion is in there somewhere....
