The Guaymas Basin is a submarine depression located on the seabed in the central area of the Gulf of California. It is the largest such basin in the Gulf. The basin results from the activity of one of the several spreading centers in the Gulf. The basin is linked to the Carmen Fault to the south, and the Guaymas Fault to the north. The Guaymas seafloor has high heat flow, hydrothermal plumes, hydrocarbon seeps, hydrocarbon plumes, and hot springs.
