Examples of thermal conductivity measurements:

Measured on drill core samples from the German Continental Deep Drilling Program KTB. (a precursoror of the International Continental Deep Drilling Program ICDP)

Example # 1: Shear zone. High resolution measurement of thermal conductivity along two profiles(1 ->) and (2 ->)

Mean results:

	Mean (W/m/K)	Min	Max	G (%)	Inhomo
Profile 1	2.78	2.2 4	3.63	11.01	0.50
Profile 2	3.04	2.4 9	3.63	7.65	0.38

 

G = Standard deviation / mean
Inhomogeneity factor  = (max-min)/mean

Thermal conductivity profiles:

Example # 2: Shear zone in hornblende gneiss. Measurement of magnetic susceptibility (courtesy of Dr. Helmuth Winter, University of Munich) and thermal conductivity along the same profile.

Mean results:

Mean (W/m/K)	Min	Max	G (%)	Inhomo
3.46	2.6 7	4.23	8.24	0.45
