Nettet5. sep. 2024 · Hydrochloric acid is used to free fossils composed of quartz and pyrite. It is also used to free rare anhydrite fossils. Fossils replaced by silica, such as quartz, opal, agate, jasper, chert, or flint, are not uncommon, especially in some areas. If some fossils in a rock layer are silicified, most of them will usually be silicified.
