Accordingly, their relative abundance, their stratigraphic position, their petrographic structure, and their paleontologic content have been the subject of special investigation. These studies disclose a radiolarian fauna in the chert, that suggests, for the chert and the accompanying graptolite shales, a syngenetic colloidal origin and deposition in the deeper reaches of the geosyncline.To the Geological Society of America, which gave a grant for the work, the writers extend their sincere thanks. They wish to thank Mr. L. M. Prindle, for information concerning the distribution of chert of Norman‐skill age in Washington County and within . . . This content is PDF only.
