Bounty Seamount
Bounty Seamount is a seamount in the Pacific Ocean, which reaches a depth of or. It is about high.The seamount is part of a group of seamounts about away from Pitcairn Island, which includes several small seamounts and the large Adams Seamount. These seamounts were discovered in 1989.
Bounty has a conical shape, with three summit cones and several rift zones. Pillow lavas and hyaloclastite cover its slopes, and parasitic vents can be observed as well. The volcano has a volume of about and has a width of at its foot. Bounty has erupted rocks with compositions of alkali basalt, trachyandesite and trachyte.Bounty Seamount was formed in several stages, and it could have developed over a time of 58,000 years. Alkali basalts from Bounty have been dated by potassium-argon dating to be 344,000 ± 32,000 years before present. Nevertheless, traces of recent volcanic activity and of hydrothermal venting have been found.
This hydrothermal venting manifests itself by the release of low-temperature fluids and the formation of iron-rich crusts. Temperatures of vented fluids amount to.
