EARLY CRETACEOUS U–PB ZIRCON AGES FOR THE COPIAPó PLUTONIC COMPLEX AND IMPLICATIONS FOR THE IOCG MINERALIZATION AT CANDELARIA, ATACAMA REGION, CHILE

Marschik R.; Söllner F. (2006)

Four of the major plutons in the vicinity of the Candelaria mine (470 Mt at 0.95% Cu, 0.22 g/t Au, 3.1 g/t Ag) and a dike–sill system exposed in the Candelaria open pit have been dated with the U–Pb zircon method. The new ...
U-PB SINGLE-ZIRCON DATING UNDER CATHODOLUMINESCENCE CONTROL (CLC-METHOD): APPLICATION TO POLYMETAMORPHIC ORTHOGNEISSES

Poller U.; Liebetrau V.; Todt W. (1997)

The dating of polymetamorphic rocks with the U-Pb zircon method often results in discordant data. Thus a new technique combining cathodoluminescence imaging (CL) and thermal ion mass spectrometry (TIMS) measurements was ...
VIEW OF AN INTACT OCEANIC ARC, FROM SURFICIAL TO MESOZONAL LEVELS: CRETACEOUS ALISITOS ARC, BAJA CALIFORNIA

Busby C.; Mattinson J.; Fackler Adams B.; Deoreo S. (2006)

The Alisitos arc is an approximately 300 × 30 km oceanic arc terrane that lies in the western wall of the Peninsular Ranges batholith south of the modern Agua Blanca fault zone in Baja California. We have completed detailed ...
