How is chert made
WebSome chert may be produced chemically. Two broad types of chert form, nodular and bedded, with abundant variations in between. Bedded chert typically forms in clastic starved basins (i.e. those with little sediment influx), along the edge of continents (such as divergent continental margins) where strong upwelling occurs.
