After years of development, geothermal energy has extensively investigated the distribution status and metallogenic law of geothermal (Hot Springs) all over the world, especially in China, conducted in-depth field investigation and Research on hot springs all over the country, and achieved a series of fruitful results. On this basis, the global geothermal resource utilization and resource analysis database and the national geothermal resource (hot spring) project database are established. The database covers typical cases of geothermal development at home and abroad. It makes a comprehensive analysis on the metallogenic types and metallogenic laws, exploration means and drilling technology, resource evaluation and other aspects of geothermal (Hot Springs) in different regions, so as to provide effective support for point-to-point rapid prediction of resource grade, positioning of borehole location and design of development scheme.
