“…The regionally extensive Middle-Late Jurassic volcanic Bahía Laura Complex(Féraud et al, 1999;Riley et al, 2001) hosts widespread epithermal mineralization of Late Jurassic age(Schalamuk et al, 1997). Location of the Claudia paleo-geothermal field (Guido and Campbell, 2014), containing the fossil geyserites described in this study, is in the easternmost portion of the Southern Belt epithermal mineralization trend.…”

“…Granites and dykes do not contain magnetite, but both contain monoclinic pyrrothite as magnetic carrier (Dekkers, 1988(Dekkers, , 1989Clark, 1984). This mineral appears disseminated and along veins and has been formed during hydrothermal mineralization together with Cu and Au enrichments during the exhumation (Díaz-Michelena and Kilian 2015; Nelson, 1996;Schalamuk et al, 1997). Despite the lower potential of pyrrhotite to produced magnetic anomalies both magnetometers clearly show high resolution and slightly positive magnetic anomalies (+30 to +80 nT) as well as higher susceptibilities of the dykes compared to the granites (Fig.…”

“…Schalamuk et al 1997). Plant fossils have been reported from a number of these environments (Marchionni et al 1999;, but fossils are sparse and preservation quality too low to allow anatomical and taxonomic description.…”

“…Geothermal activity accompanied volcanism in the region, and recent mineral exploration activity in the Deseado Massif has revealed the presence of numerous epithermal systems and terrestrial hot spring sinter and travertine deposits (e.g. Schalamuk et al 1997;Echavarría, Schalamuk & Etcheverry, 2005).…”
