The Central and Feather River peridotite belts of the northern Sierra Nevada metamorphic belt constitute a major suture zone between Paleozoic-early Mesozoic continental-margin rocks (Shoo Fly Complex and superjacent strata) of the Eastern belt and Jurassic arc and ophiolitic rocks (Smartville Complex) of the Western belt. This structurally complex zone has previously been described as a mélange. This paper presents descriptions and interpretations of the large-scale structural relations between those belts and presents evidence for the existence of six terranes separated by early, strongly deformed, low-angle faults, such as the Slate Creek thrust. The authors document the stratigraphy in detail because their choice of units and interpreted structure differ from previous studies.
