Instrumental neutron activation analysis of rocks from Cayajabos petroleum ore.
The relative INAA method under statistical control was used to measure the concentrations of Sb, La, Eu, Co, Rb, Tb, Cs, Hf, Th, Cr, Lu, Yb, Ce, Sm, Gd, Nd. Rare earth element (REE) Chondrite-normalized patterns are presented. The La(cond)/Lu(cond) normalized concentration ratios obtained confirm the carbonaceous character of the rocks.
