Of the ferruginous rocks the commonest type consists of interbanded layers in varying proportions of iron oxide, silica and combinations of the two. The silica is sometimes crystalline and sometimes cherty. The chert, however, is not truly amorphous, but consists of fine interlocking quartz grains. At times the silica is red and
