Performance of the X-ray powder diffraction (XRD), X-ray fluorescence (XRF) and the industrial computed tomography used for characterization of the vesicular volcanic rock
(Associa????o Brasileira de Energia Nuclear, 2020)
K-Ar geochronology on alkaline volcanic rocks, southern Paraná Basin, Uruguay
(Geochemical Society, 2020)
The exposed volcanic areas of the Paraná Basin in Uruguay are mainly represented by tholeiitic basalt lava flows
and related mafic intrusions, with ages restricted to the lower Cretaceous [1] [2]. Recent studies have shown ...
The effect of offset on fracture permeability of rocks from the Southern Andes Volcanic Zone, Chile
(2017)
The Southern Andes Volcanic Zone (SVZ) represents one of the largest undeveloped geothermal provinces in the world. Development of the geothermal potential requires a detailed understanding of fluid transport properties ...
Textural evidence for high-grade ignimbrites formed by low-explosivity eruptions, Parana Magmatic Province, southern Brazil
(Elsevier B.V., 2018-04-15)
The Parana-Etendeka Province is a Lower Cretaceous huge bimodal tholeiitic volcanic province (1 million.km(3)) that predated the Gondwana breakup. Its silicic portion makes up a total volume of at least 20,000 km(3) and ...
Visualization of volcanic rock geochemical data and classification with artificial neural networks
(SPRINGER/PLENUM PUBLISHERS, 2006-08)
An unsupervised neural network technique, Growing Cell Structures (GCS) was used to visualize geochemical differences between four different island arc volcanic rock types: basalts, andesites, dacites and rhyolites. The ...
