The Massachusetts Geothermal Data Project

A series of geothermal maps and datasets for Massachusetts derived from data collected by the MGS for Massachusetts and Connecticut. These data include whole rock geochemistry, rock and soil thermal conductivity, hot spring aqueous geochemistry, and derivative thermal and heatflow modeling.

The project includes multiple datasets and products which can be accessed here or via the National Geothermal Data System (http://search.geothermaldata.org/dataset?q=Massachusetts).

These datasets and products are:

Maps:
Comprising MGS Miscellaneous Maps 13-01 through 13-08

• Heat Production at the surface - showing locations of surface outcrop samples from which whole-rock geochemical analysis was performed and their heat production values at the earth's surface.
• Inferred Heat Flow - calculated heat flow (Q in mW/m^2) for sample locations shown in map above.
• Bedrock Thermal Conductivity - Thermal conductivity values for samples shown in map above.
• Soil Thermal Conductivity - Thermal conductivity values for soil / glacial cover samples with locations.
• Temperature at 3 km depth - Estimates of temperatures at a depth of 3 km below the surface
• Temperature at 4 km depth - Estimates of temperatures at a depth of 4 km below the surface
• Temperature at 5 km depth - Estimates of temperatures at a depth of 5 km below the surface
• Temperature at 6 km depth - Estimates of temperatures at a depth of 6 km below the surface
