The Gulf of California Rift Zone (GCRZ) is the northernmost extension of the East Pacific Rise which extends some 1,300 km (800 mi) from the mouth of the Gulf of California to the southern terminus of the San Andreas Fault at the Salton Sink. The GCRZ is an incipient rift zone akin to the Red Sea Rift.

Some of the fracture zones in the western Pacific Ocean are associated with the smaller plate boundaries of the active back-arc basin spreading center of the North Fiji Basin being the Hunter fracture zone and North Fiji fracture zone. The Parece Vela Rift (Parece Vela fracture zone province) is also associated with the back-arc basin of the ...
The Gulf of California is divided into three faunal regions: Northern, Central, and Southern. [citation needed] One recognized transition zone is termed the Southwestern Baja California peninsula. Transition zones exist between faunal regions, and they usually vary for each individual species.
Hydrothermal vent diagram. Hydrothermal circulation, or the circulation of hot water, is a predominant feature of the Guaymas Basin. Hydrothermalism is mainly observed in the southern trough of the basin where hydrothermal vents make up a hydrothermal complex on the seafloor by creating mounds, chimney structures, and sediments.

The rift zone known as the mid-Atlantic ridge continued to provide the raw volcanic materials for the expanding ocean basin. [20] North America was slowly pulled westward away from the rift zone. The thick continental crust that made up the new east coast collapsed into a series of down-dropped fault blocks that roughly parallel today's coastline.
Obduction zones occurs when the continental plate is pushed under the oceanic plate, but this is unusual as the relative densities of the tectonic plates favours subduction of the oceanic plate. This causes the oceanic plate to buckle and usually results in a new mid-ocean ridge forming and turning the obduction into subduction.

The Gulf of California — a gulf of the Pacific Ocean, part of the Pacific Coast of Mexico. Also known as the Sea of Cortez, Sea of Cortés, Vermilion Sea, Mar de Cortés, Mar Bermejo, and Golfo de California.
