geotermiline
Geotermiline is a term used in geology and geothermal research to describe a conceptual boundary or corridor on maps and cross-sections that marks elevated heat flow or higher subsurface temperatures relative to the surrounding crust. The term is not universally standardized and may appear in regional reports, academic papers, or software naming conventions to indicate zones of geothermal interest or thermal anomaly.
In practice, geotermiline lines are inferred from a combination of data sources, including surface heat-flow measurements,
Applications of the geotermiline concept primarily relate to geothermal energy exploration, mineral prospecting, and hazard assessment.
Limitations include data density and methodological differences, which can yield varying delineations. Temperature and heat flow
