(Table 19, page 199) Geochemistry of two ferromanganese nodules embedded in a Dogger-Malm red limestone sequence

In the region near Taormina, Sicily, the Mesozoic sedimentary veins which contain fillings have various ages ranging from Dogger-Malm until Paleocene-Ypresian. One can observe the development of graded sills parallel to the dip of the banking, formed by the superposition of limestone sequences with Globigerina, Gümbelines and Globotruncana. This study describes and illustrates these graded sills and the embedded fossil manganese nodules they contain.
