Figure 3: Schematic paragenetic sequence from aragonite or HMC ooids to a chain of distorted oomolds: A) undistorted ooids; B) weakly cemented slightly oxided ooids; C) leached ooids, i.e., oomolds; D) collapsed oomolds forming a zig-zag pattern to the left and the typographic symbol of silcrow to the right; E) to the left, photomicrograph of a zig-zag pattern sensu Carozzi (1961), Lott 19#5 4958'; to the right, photomicrograph of the typographic symbol of silcrow (§) pattern sensu Carozzi (1961), Lott 19#2 4934' (Scale bar = 250 µm). Orange: oolitic cortices; pale orange: oolitic cortices after oxidation; grey: isopachous cement; blue: pores.
