Fig. 8From: Simultaneous estimation of in situ porosity and thermal structure from core sample measurements and resistivity log data at Nankai accretionary prismThermal conductivity and in situ porosity estimated with grain thermal conductivity of 2.29 W/mK and m = 2.52. a Results for the iterative estimation started with a good initial assumption on the thermal structure. The left and right panels show depth profiles of temperature and in situ porosity, respectively. For the thermal structure, the initial assumption (Tinital), the first iterative step (Tfirst), and the final estimation (Tfinal) are shown. For the in situ porosity, the one estimated in the first iterative step (ϕfirst) and the one finally estimated (ϕfinal) are shown. b Same as a, but with a bad initial assumption for the thermal structure. c Differential depth profiles of Tfirst − Tinital, Tfinal − Tinital, and ϕfinal − ϕfirst are shown. Red and blue curves are for good and bad initial assumptions, respectivelyBack to article page
