Siliceous rock | Igneous, Sedimentary, Metamorphic
Nodular cherts appear to be produced by the alteration of preexisting sedimentary rock. In this process silica distributed throughout the rock dissolves and reprecipitates to form nodules. Mixed sediments, such as siliceous shales and limestones, also appear to be a diagenetic redistribution of siliceous organisms.
