Convective, intrusive geothermal plays: what about tectonics?
Other literature type
We revised the concept of convective, intrusive geothermal plays, considering
that the tectonic setting is not, in our opinion, a discriminant parameter
suitable for a classification. We analysed and compared four case studies:
(i) Larderello (Italy), (ii) Mt Amiata (Italy), (iii) The Geysers (USA) and (iv) Kizildere
(Turkey). The tectonic settings of these geothermal systems are different
and a matter of debate, so it is hard to use this parameter, and the results of
classification are ambiguous. We suggest a classification based on the age
and nature of the heat source and the related hydrothermal circulation.
Finally we propose to distinguish the convective geothermal plays as
volcanic, young intrusive and amagmatic.
