Chert properties. Tripolitic chert (or tripoli) is a light-colored porous friable siliceous (largely chalcedonic) sedimentary rock, which results from the weathering (decalcification) of chert or siliceous limestone. Nov 6, 2019 · Chert is a sedimentary rock made of silica, mainly from the skeletons of tiny plankton. Sep 8, 2012 · Chert is a hard and compact sedimentary rock made mostly of tiny quartz crystals. v. What is Chert? Chert is a sedimentary rock composed of microcrystalline or cryptocrystalline quartz, the mineral form of silicon dioxide (SiO 2). Chert breaks with a conchoidal fracture, often producing very sharp edges. It is usually organic rock but also occur inorganically as a chemical precipitate or a diagenetic replacement. Chert, a sedimentary rock primarily composed of microcrystalline quartz (silicon dioxide, SiO₂), is recognized for its durability and distinctive conchoidal fracture, properties historically crucial for tool-making.
