There are a variety of mineralogical and gem names for microcrystalline quartz. Bedded cherts, nodular cherts within other rocks, Banded Iron Formations (BIFs), and silcretes are the most common siliceous sedimentary rocks.
A variety of distinctive structures form in association with diagenesis.

Beyond being potentially visually striking features, these structures record processes such as the precipitation of minerals, dissolution, surface processes, and bioturbation.
