Cretaceous (possibly older) metamorphic rock occurs mainly in the Blue Mountain inlier in eastern Jamaica. Fault-bounded blocks reveal two styles of metamorphism, Westphalia Schist (upper amphibolite facies) and Mt. Hibernia Schist (blueschist (BS)-greenschist (GS) facies). Both Westphalia Schist and Mt. Hibernia Schist preserve detailed records of retrograde P-T paths. The paths are independent, but consistent with different parts of the type-Sanbagawa metamorphic facies series in Japan. For each path, phase relationships and estimated P-T conditions support a two-stage P-T history involving residence at depth, followed by rapid uplift and cooling. Conditions of residence vary depending on the level in a tectonic block. For the critical mineral reaction (isograd) in Westphalia Schist, conditions were P $7.5 kbars, T $6008C (upper amphibolite facies). Retrograde conditions in Hibernia Schist were P ¼ 2.6-3.0 kbars, T ¼ 219-2378C for a(H 2 O) ¼ 0.8-1.0 (GS facies). Mt. Hibernia Schist may represent a volume of rock that was separated and uplifted at an early time from an otherwise protracted P-T path of the sort that produced the Westphalia Schist. Reset K-Ar ages for hornblende and biotite indicate only that retrograde metamorphism of Westphalia Schist took place prior to 76.5 Ma (pre-Campanian). Uplift may have commenced with an Albian-Aptian ($112 Ma) orogenic event.
