Depth interval: SO241-47

SO241-47 - Depth interval #

A heat flow depth interval is a vertical depth interval within the Earth's subsurface, defined by top and bottom depth measurements, over which temperature measurements are taken to determine the terrestrial heat flow at a given location. This interval is used to assess the rate at which heat is conducted from the Earth's interior to the surface. The depth interval is characterized by its vertical extent, which allows for the analysis of temperature gradients and the calculation of heat flux. This data is crucial for understanding geothermal gradients, heat transfer processes, and the thermal structure of the Earth's crust at that location.
