Next Reports Footwall Refrigeration Along a Detachment Fault: Implications for the Thermal Evolution of Core Complexes Jean Morrison, * J. Lawford Anderson Oxygen isotope compositions of epidote and quartz from chloritic breccias that underlie the detachment fault in the metamorphic core complex of the Whipple Mountains yielded quartz-epidote fractionations that range from 4.1 to 6.4 per mil and increase systematically toward the fault.
