Description

The geochronological study of the Massif of Troia-CE, Brazil, for identifying different parastratigraphic units is presented. A previous selection by macroscopic, microscopic and X-ray fluorescence analysis for Rb/Sr determinations in whole rock, and K/Ar determinations in mineral was carried out. (M.C.K.)
