Figure 2: Schematic paragenetic sequence from aragonite or HMC ooids to a chain of distorted oomolds (redrawn and adapted from Conley, 1977, Fig. 8): A) undistorted ooids; B) cemented slightly oxided ooids; C) leached ooids, i.e., oomolds; D) collapsed oomolds; E) transmitted light; F) reflected light. E-F: Lott 19#4 4918' (Scale bar = 250 µm). Orange: oolitic cortices; pale orange: oolitic cortices after oxidation; grey: "blocky" cement; blue: pores.
