Preliminarily, on the basis of a wide set of field measurements over unaltered outcrops, we obtained a reference spatial distribution of U, Th and K. The concentration of these radioelements increases with the degree of magma differentiation; the U and K content shows maxima in the felsic materials, belonging to the youngest volcanic cycles (13.4 ppm and 3.7% on average, respectively), and minima in the mafic rocks of the oldest cycles (2.7 ppm and 2.0%). The Th/U ratio insignificantly varies with magma differentiation and it equals 3.2. Laboratory measurements on volcanic products from altered zones were then used to identify radiometric anomalies related to hydrothermal processes. On average, argillized rocks have radioactivity approximately five times lower than that measured in the unaltered volcanics. The Th/U ratio against U is rather uniform, whereas Th/K ratio is in the order of 3.7 in less altered rocks (K > 0.2%) and it ranges from 7 to 11 in kaolin deposits having the largest depletion in potassium.","PeriodicalId":268242,"journal":{"name":"Environmental Semeiotics","volume":"405 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124162034","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the research is to improve the detection of water fluxes in the vadose zone by using a self-potential tomographic technique which gives a 4D (3D + time) high resolution image of water movements within the soil subsurface. Several water infiltration experiments were performed in both field and lab conditions. In this case, particularly, the experiments were performed by using a sand box (7.0 x 3.5 x 2.0 meters) which allows to be reproduced a medium-large scale natural environment. SP signals were recorded continuously by using an array of 32 unpo-larizable electrodes connected to a multiplexed high impedance and resolution multimeter. Better results came out from laboratory experiments where most of the so called cultural noise was reduced at a negligible amount. The results have proved that SP tomographic images represent a good tool for monitoring the changes of water fluxes in the vadose zone under the boundary conditions which are discussed in the work.","PeriodicalId":268242,"journal":{"name":"Environmental Semeiotics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128775188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
