3He/4He ratios in and around Teide volcano, Tenerife, Canary Islands, Spain
(Sociedad Geológica de España, 1996)Helium-3 emission spatial distribution in and around Teide volcano, Tenerife, Canary Islands, has a quite different pattern from other stratovolcanoes which show usually a decreased trend for the 3He/ 4He with respect to ... -
Anomalous soil gas C02 concentrations and relation to seismic activity at Rabaul caldera, Papua New Guinea
(Sociedad Geológica de España, 1996)Medidas de C02 en los suelos de la caldera de Rabaul, Papua Nueva Guinea, reflejan niveles de concentración altos, hasta cerca de un 20%, en relación con un margen activo de la caldera definido por sismicidad. Estos niveles ... -
Distribution and origin of soil gas C02 and CH4 in and around Cañadas caldera, Tenerife, Canary Islands, Spain
(Sociedad Geológica de España, 1996)The distribution and origin of soil gas C 0 2 and C H 4 were investigated to have abetter understanding on the levels of diffuse degassing at the surface environnent of Cañadas caldera (Tenerife, Canary Islands). Soil gas ... -
Preliminary results on 3He/4He isotopic ratios in terrestrial fluids from Iberian peninsula: seismoctectonic and neotectonic implications
(Sociedad Geológica de España, 1996)La sistemática de isotópos de helio está siendo aplicada en la península Ibérica con el fin de obtener información adiccional sobre las características neotectónicas y sismotectónicas del área de estudio. Resultados ... -
Soil gas 222Rn, He, and 220Rn/222Rn ratios at Cañadas caldera, Tenerife, Canary Islands, Spain
(Sociedad Geológica de España, 1996)Soil gas 222Rn distribution suggest a close relationship with volcanic-geothermal features in and around Cañadas caldera according to both 1992 and 1995 soil gas suiveys. Three transects were selected for soil gas 222Rn, ...
