I think the processes you may be wondering about here are not thermal;
rather the "different colors" you refer to are often a convenient output
schematic for visualizing variations in forced electrical current through
the ground or relative variations in magnetic field strengths, using
resistivity detectors and magnetometers respectively. To be sure I am no
expert in these methods, but I have used them for a similar purpose and met
with mixed results. Their value is substantial, however, and for a good
general introduction to these methods check out a recent textbook like
Hester, Shafer, and Feder's "Field Methods in Archaeology." The bib should
lead you from there. Best of luck.

I am looking for information on thermal sensing to locate unmarked
graves. I am not exactly sure what the technique is called. It involves
different temperatures of the soil showing up in different colors.
