Tectonic setting of blueschist and island-arc terranes of west-central Baja California, Mexico

Características geológicas y potencial metalogenético de los principales complejos ultramáficos-máficos de México

“…La mélange de Puerto Nuevo aflora como una ventana tectónica que corta rocas ofiolíticas y consiste en bloques de brechas de serpentinita, esquistos verdes, esquistos azules, ortogneiss, anfibolitas y eclogitas (Sedlock, 1988).…”

“…La mélange de Puerto Nuevo aflora como una ventana tectónica que corta a las rocas ofiolíticas, y consiste en bloques de brechas de serpentinita, de esquistos verdes, esquistos azules, ortogneiss, anfibolitas y eclogitas (Sedlock, 1988). La serpentinización es ubicua en las rocas ultramáficas (>95% de la roca), mientras que la rodingitización sugiere un metasomatismo hidrotermal cálcico.…”

Remagnetization of Cretaceous forearc strata on Santa Margarita and Magdalena Islands, Baja California Sur: Implications for northward transport along the California margin

“…These oceanic rocks are separated from Paleozoic and Mesozoic continental rocks to the east by an inferred major fault boundary beneath Cenozoic sedimentary rocks and the Pacific Ocean [Sedlock et al, 1993]. Unmetamorphosed Cretaceous strata unconformably overlie Late Triassic to Late Jurassic island arc and ophiolitic rocks that, in turn, structurally overlie coherent blueschists along shallowly dipping normal fault systems [Sedlock, 1988[Sedlock, , 1993[Sedlock, , 1996. The Cretaceous strata include terrigenous sandstone, shale, and conglomerate that probably accumulated as turbidites in a forearc basin or basins.…”

Geology and tectonics of the Baja California Peninsula and adjacent areas

“…The Cochimí terrane consists of Mesozoic blueschist, ophiolite, and island-arc terranes overlain by Cretaceous forearc basin strata (Rangin, 1978;Kimbrough, 1985;Moore, 1985;Sedlock, 1988bSedlock, , 1999Kimbrough and Moore, this volume). These oceanic rocks crop out on Isla Cedros, Islas San Benito, and the Vizcaíno Peninsula near 28°N and on Isla Magdalena and Isla Santa Margarita near 24°30'N ( Fig.…”
