The most common value of Unbiased Geothermal Temperature Gradient away (GT) away from tectonic plate boundaries : GT boundaries is: 030 °C/m.
The difference between Geothermal Temperature Gradient (GradTG) and Unbiased Geothermal Temperature Gradient (GradTGN) is that the former accounts for the effects of the seasonal/daily temperature variations, which are only significant above Neutral Temperature Layer.
