Opal is a sedimentary stone. Under the proper conditions, water percolates through the earth, becoming rich in dissolved silicates. When water enters a cavity, it deposits the silicates as microscopic spheres, forming opals. If the spheres are uniform in size and shape and neatly stacked, they will diffract light. The pore size distribution of stones is one of the most important properties influencing stone decay. Pore distribution conditions the absorption and ...Jan 1, 2021 · A 0.5-m-thick oolitic ironstone bed is the lowest exposed unit in the section (Fig. 4 a).
