Not illustrated. 1899 Excerpt: ...which have long been known in Trinidad as the Naparima Marls. In his historical introduction Mr. Jukes-Browne deals with the writings of Mr. Guppy and Prof. Harrison, and shows that three definite issues are thus raised: (1) Are the Nariva Beds above or below the Naparima Marls? (2) Do the Gloiigeritta-maxls occur in the Naparima district, and, if so, are they connected with the Radiolarian marls, or are they part of a separate formation? (3) What is the relation between the San Fernando Beds and the other groups? Mr. Guppy and Prof. Harrison agree in answering the first part of the second question in the affirmative, and in stating that the two marls are closely connected together. It appears that the Globigerina-maxXs occupy the place of the basal chalks of Barbados, but are much thicker, while the radiolarian rocks arc thinner, and the interbedded volcanic ashes so frequent in Barbados are wanting in Trinidad. Chemical and microscopic analysis of the Globigerina and radiolarian beds are given, and, compared with similar analyses of the Barbadian deposits, they show that more quartz and argillaceous matter occur in Trinidad. The following correlation is proposed: --Trinidap. I Moruga Series. Naparima Marls. Barbados. Coral Rocks. Bissex Beds. / Oceanic Neds. /Pleistocene and. Pliocene. Miocene. Oligocene and f Oligoce I Eocene The Oligocene and Eocene Beds are of shallow-water origin, and seem to be unconformably covered by the Naparima Marls. Paris.
