when does coldchick evolves in pokemon quartz?
There would be a bias against counting calcite-cemented arenites and sandstones because the rates of erosion are higher given the higher dissolvability of calcite and hence higher weatherability in humid temperate climates, diminishing their prominence. But it is certainly true that quartz and silica are among the most common. Also compacted shales are impermeable clastic rocks that don't have quartz cement.
