From: Evidence for the late formation of hydrous asteroids from young meteoritic carbonates

Figure 3

Temperature (solid lines) and the extent of alteration (dotted lines) are given at three depths (r: distance from the centre) in the asteroid with a radius of 30 km. The vertical grey band shows the formation age of carbonates (). (a) Accretion at 3.5 Myr after CAI formation (case A). The extent of alteration is defined by (1−olivineres./olivineini.), where olivineres. and olivineini are the moles of the residual and initial olivine, respectively. (b) Accretion at 3.0 Myr after CAI formation (case B). Note that the hydration reaction is not included in case B.
