.... The Maya Mountains plutons yield a paleopole that is statistically identical to that of the Chiapas Massif to the south. Both plutonic complexes exhibit somewhat dispersed dual polarity magnetization populations, suggesting that both were remagnetized at ca. 230 Ma. Importantly, the identical remanences...

The Tahamí terrane can be correlated with blocks now occupying southern Mexico (Chiapas Massif) and the northwestern Andes (Loja and Amotape) and perhaps the late Paleozoic-Triassic components of the Marañón complex in Peru. These areas underwent crustal reworking...
