Magnetic petrology of the Água Azul and Água Limpa granodiorites, southern portion of the Carajás Domain – Pará [PDF]
The Água Azul and Água Limpa granodiorites (AAGrd and ALGrd, respectively) outcrop in the extreme southern of the Carajás Domain as two elongated bodies following the EW regional trend and were previously included in the Xingu Complex. The ALGrd consists

Insights from elastic thermobarometry into exhumation of high-pressure metamorphic rocks from Syros, Greece [PDF]
Retrograde metamorphic rocks provide key insights into the pressure–temperature (P–T) evolution of exhumed material, and resultant P–T constraints have direct implications for the mechanical and thermal conditions of subduction interfaces.

Solid Solution Between Epidote and Hancockite from Nezilovo, Macedonia
A solid solution between the epidote formula and hancockite formula (Pb equivalent of epidote) was found in the “mixed series” of the Pre-cambrian complex in the central part of the Pelagonian massif near the village of Nezilovo.
