| Field Description | Principal method of heat-flow calculation from temperature and thermal conductivity data. Allowed entries: controlled vocabulary |
| Allowed range of values | [Interval method] [Bullard plot] [Boot-strapping] [Numerical inversion] [Other (specify in coments)] |
| Value description | [Interval method]: Fourier's Law or Product or Interval method - product of the mean thermal gradient to the mean thermal conductivity with reference to a specified depth interval]; [Bullard plot]: heat-flow value given as the angular coefficient of the linear regression of the thermal resistance vs. temperature data (used when there is a significant variation of thermal conductivity within the depth range over which the temperatures have been measured)]; [Boot-strapping]: iterative procedure aimed at minimize the difference between the measured and modelled temperatures by solving the 1-D steady-state conductive geotherm (radiogenic heat production of rocks is accounted for); [Numerical inversion]: Computational inversion of borehole heat transport model |
