The Temisas Carbonate Building: an example of a thermogene tufa system in Gran Canaria Island
[EN] The Temisas Carbonate Building (TCB) is situated in the Temisas ravine, at the SW part of the Gran Canaria Island. Four different facies were recognised: detrital, framestone, phytoclastic and a transition between the last two facies. The carbonate is mostly calcite. The sedimentary sequence in...

| Summary: | [EN] The Temisas Carbonate Building (TCB) is situated in the Temisas ravine, at the SW part of the Gran Canaria Island. Four different facies were recognised: detrital, framestone, phytoclastic and a transition between the last two facies. The carbonate is mostly calcite. The sedimentary sequence indicates that the TCB was formed in a fluvial system with different subenvironments, such as cascades, channels and bars. The studied deposits correspond to the distal part of a calcareous spring deposit. Petrologically these deposits can be included in the term tufa. The stable isotope values indicate thermal origin for the CO2, so from the geochemical point of view the TCB should be considered a thermogene tufa. |
