I need to know the heat gradient on restricted environmental area (protection area).
I can't drill a hole then I need use an indirect method.
I think that the geophysics could be the way.
Thanks for any help.

Have you investigated the various regional databases?
Have you considered drilling just outside the restricted area?
Dear Ernest,
Unfortunately this is a remote area. We don't have just outside....every land in the region is restrict. My apologies, but right now I can't tell where is.
Where I can find this regional databases?
Do you know if can I use Magnetometry, IP, Magnetotellurics or other geophysics method to infer the thermal gradient of the crust?
Thank you!
Regards,
Francisco
Regional databases for geothermal gradient and heat flow?
1. GeoMapApp is an earth science exploration and visualization application that is continually being expanded as part of the Marine Geoscience Data System (MGDS) www.geomapapp.org
2. The web site http://www.mantleplumes.org/index.html contains references to all areas thought to be situated above Mantle Plumes: thus the quote, in geothermal circles, ”If it’s really hot it’s at Mantle Plumes”,
3. New Global Heat Flow Compilation http://www.heatflow.und.edu/data.html.
4. http://www.iaspei.org/commissions/IHFC.html
5. NGDC Global Heat Flow Data (Pollack et al. 1993) http://gisandes.brgm.fr/gis_heat-flow_ihfc.htm
After you try the above databases you can try magnetics and magnetotellurics to infer the crustal thickness, possibly leading to inferences on the thermal gradient.
