Rb-Sr and 207Pb/206Pb(zircon) radiometric data for the granitoids yield crystallization ages at ca. 2.0 Ga. The calculated 87Sr/86Sr initial ratios (up to 0.727), TDM model ages (between 2.6 and 3.5 Ga) and the range in the eNd(t) values (-5.8 to -13.4) are all compatible with participation of variable proportions of Archean crust material in the magma genesis of such plutons. Technically, these granites originated due to the Transamazonian collisional orogeny, which developed within large terranes of the Craton along the edge of the Archean Gavião Block.Submitted by Ana Valéria de Jesus Moura (anavaleria_131@hotmail.com) on 2011-09-06T14:51:26Z No. of bitstreams: 1 10577-35525-1-PB.pdf: 473749 bytes, checksum: d98ed66be5095562a10b93091e9d7878 (MD5)Made available in DSpace on 2011-09-06T14:51:26Z (GMT).
