One hundred and thirty new chemical analyses related to the Paraná Basin basaltic rocks are registered. Based on the new data obtained from samples collected all over the province, statistical parameters related to major elements content in these rocks are reviwed. Statistical treatments applied in a sample formed by the greatest part of available chemical data related to these rocks, support differences already shown between the chemical characterises of the rocks in the province, and the chemical characteristics of their equivalents in other regions of Gondwanaland. Multivariate statiscal analysis raises also evidences which show other type of differences which distinguish the province from reference patterns based in data of world distribution. The large dispersion obeserved for all major element distributions and the high content in iron and alkalies combined with the low content of magnesium and calcium suggest that the basaltic rocks from Southern Brazil are generally differentiated. Distribution patterns suggest also that the province apparently do not have homogeneous chemical characteristics, represented by distributions of the normal type, but is represented by multipopulational distributions whose significance has to be determined.
