High-pressure/low-temperature metamorphic rocks in the Franciscan Complex of western California are primarily found as small blocks in mud-matrix melange and as extensive coherent, bedded sheets or slabs. The highest-pressure rocks, the high-grade sodic and/or calcic amphibole-epidote-garnet-omphacitic pyroxene- bearing blueschists, amphibolites, or eclogites, are found as blocks (typically meters to a few tens of meters across) in the melanges. Low-grade schistose blueschists are found as small blocks in melanges and in extensive coherent belts. Many Franciscan greenstones and metagraywackes in both the melanges and coherent tracts locally contain sodic pyroxene + quartz, lawsonite, and/or aragonite but are neither blue nor strongly schistose. Petrotectonic constraints on models for uplift and preservation of Franciscan high-pressure/low-temperature metamorphic rocks are included.
