Chert is typically of biological origin, and it is created by introducing dead sea life during its formation. However, it can also occur inorganically as a chemical precipitate or as a diagenetic replacement (such as in petrified wood).Quartz is a mineral composed of silicon and oxygen, with a chemical composition of SiO 2. It is the most abundant mineral in Earth's crust and is resistant to both chemical and physical weathering. When rocks weather away, the residual material usually contains quartz. This is why the sand at most of the world's beaches is quartz.Quartz is one of the most abundant minerals on earth and is found in many rock types including igneous, metamorphic, and sedimentary rocks. It is particularly common in continental crust rocks such as granites and rhyolites, and in sedimentary rocks such as sandstones and cherts.
