Webtracer for the axial hydrothermal heat flux we know that the amount of heat produced at a typical vent is 36 x 108 cal/cm2; about 3 x 1010 cm2/yr of new crust is made each year. a. Using these data, calculate the heat flux out of hydrothermal vents, assuming that 35% of the heat is lost by convection and the remainder by conduction. b. WebResults suggest that the chromium component in ultramafic rocks could be an important factor for FTT synthesis during water-rock interaction in mid-ocean ridge hydrothermal systems. This in turn could help to support microbial communities now recognized in the subsurface at deep-sea vents. 展开
