Deformation and geochronology of syntectonic granitoids emplaced in the Major Gercino Shear Zone, southeastern South America
(ELSEVIER SCIENCE BV, 2010)
The Major Gercino Shear Zone is one of the NE-SW lineaments that separate the Neoproterozoic Dom Feliciano Belt, of Brazil and Uruguay, into two different domains: a northwestern supracrustal domain from a southeastern ...
Petrogenesis of the metacarbonate and related rocks of the silgará formation, central santander massif, colombian andes: an overview of a “reaction calcic exoscarn”
(UNIVERSIDAD NACIONAL DE COLOMBIA, 2008)
Metacarbonate rocks (pure and impure marbles, carbonate-silicate rocks, calc-silicate rocks and carbonate-bearing silicate rocks) form a very complex group within the metamorphic sequence of the Silgará Formation at the ...
Morpho-structural evolution of the Cordon Caulle geothermal region, Southern Volcanic Zone, Chile: Insights from gravity and Ar-40/Ar-39 dating
(ELSEVIER SCIENCE BV, 2005-11-15)
The Cordon Caulle geothermal region (40.5 degrees S) is a 13 km X 6 kin, NW-SE elongate, volcano-tectonic depression hosting numerous monogenetic volcanic centers, fumaroles, and hot-springs, most of which occur spatially ...
Tolerance to partial and complete submergence in the forage legume Melilotus siculus: An evaluation of 15 accessions for petiole hyponastic response and gas-filled spaces, leaf hydrophobicity and gas films, and root phellem
(Oxford University Press, 2019-01)
• Background and Aims: Submergence is a severe stress for most plants. Melilotus siculus is a waterlogging- (i.e. root zone hypoxia) tolerant annual forage legume, but data were lacking for the effects of partial and full ...
Radial oxygen loss and physical barriers in relation to root tissue age in species with different types of aerenchyma
(Csiro Publishing, 2015-01)
Plant root aeration relies on aerenchyma and barrier formation in outer cortex influencing the radial oxygen loss (ROL) from roots towards the rhizosphere. Plant species display large variation in strategies for both ...
