Summary The heat flow in the Broken Hill region has been determined from temperatures measured in 18 deep depressed drill holes covering an area of 200 square miles and in 32 horizontal drill holes in mine walls. 118 thermal conductivity determinations on rock specimens representative of the area have been used. The values of heat flux range from 1.81 to 2.07 μcal/cm 2 s with a mean of 1.93. The standard error of a single determination is about 5 per cent.
