Experimental and natural mimetic dolomitization of aragonite ooids

Abstract:

Comparison of experimental fabrics with calcitized, partially dolomitized and completely dolomitized aragonite ooids of the late Proterozoic Beck Spring Dolomite indicates that mimetic concentric fabric originates by aragonite dissolution and early dolomite precipitation within porous cortical laminae. Importantly, these experimental and natural "replacement' fabrics show that fine-scale dolomite ooid fabrics are not indicative of "primary' dolomite precipitation. -from Authors
