Convection-Dominated Geothermal Systems:
The transportation of geothermal heat is dominated by convection
Other definitions:Wikipedia Reegle


Convection dominated geothermal play types are considered ‘viable’ or ‘active’ geothermal systems because they are adjacent to regions of active tectonism, active volcanism, young plutonism, and extensional tectonics. All known ‘high temperature’ (>200°C) geothermal reservoirs shallower than 3,000m are in this category. The heat is transferred as a fluid from deeper to shallower crust by means of convection along permeable pathways. The primary reservoirs are highly permeable porous formations that are laterally extensive. [1]

The play types included in this category are magmatic plays which can be either extrusive or intrusive, plutonic plays with active or recent volcanism, inactive volcanism, and extensional domain plays.
