The pyrite linings in thin sections are visible as linings formed by pyrite framboids dispersed on interior valve surfaces (black grains in Fig. 7b–d) and in the conchiolin layer (Fig. 7e). Pyrite linings are frequently associated with internal fine-scale dissolution and can co-occur with isolated reddish grains of Fe oxides at all sites.

What is Pyrite. Commonly called fool's gold, pyrite is the Earth's most abundant sulfide mineral. Recognized for its brass-yellow color which resembles that of gold, pyrite is a source of iron and sulfur and is used for the production of sulfuric acid. Some types of pyrite contain enough microscopic gold to warrant mining them as a gold ore.

What is "Fool's Gold?" | U.S. Geological Survey

Fool's Gold can be one of three minerals. The most common mineral mistaken for gold is pyrite. Chalcopyrite may also appear gold-like, and weathered mica can mimic gold as well. Compared to actual gold, these minerals will flake, powder, or crumble when poked with a metal point, whereas gold will gouge or indent like soft lead. In addition, actual gold will leave a golden yellow streak …
