Ocean crust age my

Fig. 7.7. The highest temperature (Celsius) reached beneath the old oceans after an ocean-vaporizing impact. The temperatures are given as a function of depth and heat flow. The crustal age corresponding to a heat flow is also given. Temperatures suitable to hyperthermophiles are widespread, but temperatures suitable to "mesophiles" (here rather liberally equated to thermophiles that thrive or at least survive at 60° C) are found only below 1 km in regions of low heat flow.
