Abstract
Concentrations of 32 elements in 22 clay, limestone, tuff and volcanic rock samples from the Pina ore have been obtained by neutron activati on and x-ray fluorescence analyses. Several LILE (large ion lithofile elements) and REE (rare earth element) concentration diagrams showed t he calc-alkaline character of the volcanic rocks corresponding to the Greater Antilles Island, Arc. The basaltic andesite behavior of the ro cks studied was confirmed by comparing the average concentrations obta ined from tuffs and volcanic rocks with proper mean values of rock ele mental compositions of the earth's crust.
