Abstract:

For nearly three centuries, the vecinos of colonial Paraguay defended Spanish interests in the Upper Plata. Turbulent as they were, protesting with violent regularity against unpopular governors and official policies, these “hijos del país” have traditionally been portrayed as the bedrock from which the Paraguayan people and identity sprang. Offspring of the Spanish conquerors of the 1500s and their guaraní consorts, the “mancebos de la tierra,” possessed the full rights of Europeans. They guarded their noble status jealously, while dominating the rural society of the province. With the passag

Data on Silica content of ground waters have been employed in obtaining estimates of heat flow for more than 500 localities, distributed over six tectonic provinces in Brazil. The procedure adopted is based on the use of an improved geo-thermometry relation for solubility of silica in ground waters. It is coupled with a revised interpretation of the empirical relation between silica content and heat flow, that allows for independent determination of the depth of circulation of ground waters.

However, little is known about the effects of this anthropogenic activity on the floral origin of honey or the statistical tools that could be used to analyse it. The objective of the present study

Abstract. There has been little research on volcanological aspects of Paraná continental flood basalts (PCFBs), and all investigations have mainly been concentrated on the internal portions of the lava flows. Thus, this study describes for the first time morphological aspects of lava flows and structural characteristics caused by lava–sediment interaction in the northwestern PCFB province (NW-PCFB). Early Cretaceous (134 to 132 Ma) tholeiitic rocks of the PCFB were emplaced on a large intracratonic Paleozoic sedimentary basin (Paraná Basin), mainly covering dry eolian sandstones (Botucatu Form

Abstract:

A new species of Crenicichla Heckel, C. hu, is described from the arroyo Piray–Miní, a left-hand tributary of the río Paraná, Misiones province, Argentina. This new species is easily distinguished from its congeners in the La Plata basin and adjacent coastal rivers by the dark coloration (dark grey or dark brown to black), a color pattern consisting of 7 to 9 black irregular blotches on the flank, and 47–54 scales in the E1 row. Adult females have dorsal fin with an irregular color pattern formed by wide black and white longitudinal stripes and blotches. In addition to standard morphological c

Abstract:

This article analyzes the editorial position of El Nacional Argentino newspaper from Paraná, Entre Ríos in relation to the economic policy of the confederated provinces in the complex juncture of an Argentina divided into two States: Argentine Confederation and State of Buenos Aires. The aforementioned journalist entity, during 1854, undertook the task of making the benefits of Plan Fragueiro, the realities of the provinces and the mining, craft and commercial wealth of the Confederation known, with the aim of attracting people and capitals that ensure the grown of the financial resources whic

Abstract:

The great economic and political changes in the Río de la Plata of the late 1700s penetrated not only Buenos Aires and the interior of present-day Argentina, but upriver the hitherto neglected province of Paraguay shared the reforms of the Intendant system and economic liberalization. Those changes, along with the expulsion of the Jesuits, produced a shift in the economy of this region from the Paraná-Tebicuary area to the northern frontier of that province. The impelling economic motive for that shift was the north's greater ability to meet the demand for Paraguay's primary export, yerba mate

Ophrydium versatile, a green protozoon that form sessile colonies is reported for the first time for the Misiones province, Argentina from shallow waters of a recently formed pond in the Garupá stream floodplain, at about 900 m away from the confluence with the High Paraná River. To our knowledge this constitutes the second and northernmost record of the species for Argentina and the first for a subtropical environment in the country.

Abstract:

The Entre Rios mining district produces a large volume of amethyst geodes in underground mines and is part of the world class deposits in the Paraná volcanic province of South America. Two producing basalt flows are numbered 4 and 5 in the lava stratigraphy. A total of seven basalt flows and one rhyodacite flow are present in the district. At the base of the stratigraphy, beginning at the Chapecó river bed, two basalt flows are Esmeralda, low-Ti type. The third flow in the sequence is a rhyodacite, Chapecó type, Guarapuava subtype. Above the rhyodacite flow, four basalt flows are Pitanga, high
