O circuito espacial produtivo e os círculos de cooperação da carcinicultura do Rio Grande do Norte

Suponiendo que la dinámica territorial del período histórico actual se caracteriza por la nueva división territorial del trabajo, por la especialización regional productiva y por la racionalidad que preside el movimiento de las mercancías y de la información, la teoría de los circuitos espaciales de producción se convierte fundamental para la comprensión de la organización, regulación y del uso de territorios por las actividades productivas. Así, teniendo en cuenta este supuesto y aplicando esta teoría para analizar el área de la producción de camarón en el estado de Rio Grande do Norte, se llega a comprender la dinámica del territorio Potiguar. Por lo tanto, en nuestro trabajo pretendemos entender el movimiento, la secuencia de los casos que geográficos que separan la producción, distribución, intercambio y consumo de camarón Potiguar, en este momento, sobre todo a partir de la década de 1990, sucede la expansión del cultivo de camarón en la costa norte Riograndense. La investigación ha demostrado que a pesar de la presencia de un gran número de agentes en la actividad, hay un control y una concentración del circuito en las manos de grandes empresas. Este control se pasa por el reducido número de agentes de venta de larvas, alimentación, maquinaria e insumos. Y con respecto a la concentración, esto ocurre sobre todo en la etapa de producción en las haciendas de engorde. En este caso, podemos decir que hay un predominio de los pequeños productores en números absolutos en el cultivo de camarón potiguar, ya que gran parte de los emprendimientos tienen dimensiones inferiores a 10 ha. Sin embargo, cuando analizamos las empresas de gran escala, éstos, a pesar de representar un porcentaje menor del total, concentran casi la mitad de las áreas cultivadas, además de tener en el control de gran parte del movimiento establecido por el circuito espacial productivo de la producción de camarón. Así, aparecen en el circuito espacial productivo de la producción de camarón de Rio Grande do Norte, las diferencias cualitativas de los usos del territorio entre los agentes que participan de este circuito. Porque un número limitado de agentes tienen las mayores áreas productivas, son dotados de un mayor nivel de tecnificación y tienen, hasta cierto punto, el control del movimiento de su producto, mientras que, eso no se reproducen por otros agentes, especialmente aquellos dedicados a la producción, efectiva, en las haciendas de engorde

Caracterização petrográfica dos alvos Hidrotermalitos Norte e Sul, Suruca e porção NW da Mina de Chapada - Alto Horizonte, GO

Main occurrence of Cu-Au in Goias Magmatic Arc, the Chapada mine fits into the geological context of the Brasilia Fold Belt, specifically in the Mara Rosa Magmatic Arc. Four targets, named Hidrotermalito Norte and Sul, NW Chapada Mine Portion and Suruca, are situated in this context, which includes ortogneisses and rocks from the Mara Rosa volcanic-sedimentary sequence. All these targets have been studied due to the possibility of presenting a great potential in Cu-Au, as well as the Chapada mine. Hidrotermalitos Norte and Sul targets presents four lithological sequences, which were identified as: quartz-muscovite schist; muscovite quartzites and kyanite quartzites; quartz-biotite-amphibole schist with pyrite and epidote-amphibole-biotite gneisses with muscovite; muscovite-biotite gneisses. They are metamorphosed to amphibolites facies and retrogressive greenschist facies. Sulfetation represented mainly by pyrite. In the NW Chapada Mine Portion, three main lithological groups were identified and classified as biotite gneisses; honblende-quartz-biotite-schist; amphibolites, with the first group metamorphosed in greenschist facies (low grade), and the other two groups metamorphosed in amphibolites facies, with subsequent retrogressive metamorphism in greenschist facies. Sulfetation is represented by chalcopyrite and pyrite. Finally, also three main lithological groups were identified in the Suruca target, classified as garnet-chlorite-epidote-eiotite gneiss; biotite gneiss and chlorite-biotite gneiss with epidote and muscovite; muscovite-quartz schist, all them metamorphised in amphibolites, with retrometamorphism in greenschist facies. Sulfetation represented by pyrite and sphalerite

Mapeamento geológico e petrologia dos complexos máfico-ultramáficos de Mangabal Sul e Mangabal Norte, região de Sanclerlândia, Goiás

The Mangabal Sul and Mangabal Norte mafic-ultramafic complexes are interpreted as intrusive stratiform bodies in the Goiás Magmatic Arc during the Brazilian cycle, being economically important for harboring significant amounts of nickel and copper sulfides. The main lithotypes of the complexes are gabbronorites, olivine gabbronorites, pyroxenites and peridotites, with variated degrees of deformation, recrystallization and metamorphism superimposed, with metamorphic peak of amphibolite to granulite facies evidenced mainly by the occurrence of coronitic olivine in metamafic rocks and the occurrence of syn-kinematic retrometamorphism associated with the development of the main foliation Sn. The Sn foliation planes show NE-SW preferential direction, consistent with the foliation direction of VIII the enclosing gneisses and schists, also concordant with the general elongation of mafic and ultramafic bodies displayed on map. The sulfide phase presents textures that indicate remobilization, associated with the occurrence of significant amounts of rutile within the ore which reinforces this idea. Along with the sulfides, the occurrence of expressive quantities of titanium oxides such as ilmenite and rutile, make the area more economically attractive. It can be suggested that the Mangabal Norte and Mangabal Sul complexes are contemporary, have the same genetic affinity and suffered the same deformational and metamorphic processes, evidenced by their structural and petrological similarities

Ocupaçâo, valorizaçâo e comércio de terras no norte do Rio Grande do Sul - séculos 19 e 20

This article focuses on some aspects of the agrarian history of Soledade, a town in the north of the state of Rio Grande do Sul, southern Brazil. Our aim is to understand how this area was in many ways affected by the Land Law of 1850, particularly in economic and social terms. Population growth, arrival of European immigrants and increasing privatization of the commons contributed for the increasing of land prices in the region during the second half of the 19 th century. Understanding this situation as a great opportunity to make money, some landowners, directly or through a colonization company, allotted and sold the land they had previously acquired through the Land Law of 1850
