Повний текст джерелаO trabalho consiste na análise estratigráfica do intervalo siluro-devoniano da Bacia do Amazonas utilizando como base os conceitos da Estratigrafia Moderna, mais especificamente a sequência estratigráfica genética, proposta por Galloway (1989), a qual utiliza as superfícies de inundação marinha como os limites de uma sequência sedimentar. A principal razão para a utilização desta metodologia deve-se ao fato que o conteúdo rochoso compreendido no intervalo estudado teve a sua sedimentação relacionada às transgressões marinhas que faziam parte do contexto paleogeográfico da bacia durante o Siluriano e Devoniano. Desta forma, as superfícies de inundação máxima, representativas de eventos cronoestratigráficos, destacam-se nos perfis de raios gama e são tomadas como datum de correlação em treze poços exploratórios, os quais foram distribuídos em quatro seções (A-A, B-B, C-C e D-D) pela bacia. A análise destas seções permitiu a identificação de quatro sequências de terceira ordem (AB, BC, CD e DE), limitadas no topo e na base por superfícies de inundação marinha. Cada sequência é constituída por ciclos regressivo-transgressivos assimétricos, representados pelo trato de sistemas de mar alto e pelo trato de sistemas transgressivo. A análise destas seções integrada à interpretação de mapas estratigráficos (isópacas, isólitas e porcentagem de areias) possibilitou identificar o depocentro da bacia, bem como duas áreas principais como fonte de sedimentos arenosos (uma a oeste e outra a sul). Além disto, foi possível inferir que a comunicação marinha com o continente, durante as transgressões paleozoicas, responsável pela deposição de sedimentos pelíticos, seguiu uma orientação de norte para sul, evoluindo obliquamente em direção ao continente num trend nordeste para sudoeste. Por fim, a partir da análise cíclica em perfis de raios gama, as superfícies de inundação marinha, do intervalo Devoniano, das bacias do Amazonas e Parnaíba foram correlacionadas.

The most important diagenetic processes were early marine cementation and shallow burial diagenesis, and in the southwestern Moose River Basin early secondary dolomitization.

Повний текст джерелаThe Lions Head and Colpoy Bay members of the Amabel Formation are continuous in core across the Bruce Peninsula. These members contain characteristic dark grey mottles which are the result of increased porous zones and pyrite, and/or concentrations of undifferentiated organics. Chert nodules and the abundance of silica is most abundant in the upper Lions Head Member where silica-replaced fossils are recognized within the surrounding dolomite. Typical Wiarton Member crinoidal lithofacies from the upper Amabel Formation are more common in the southern half of the Peninsula. The Eramosa Member is more laterally continuous on the Bruce Peninsula than previously assumed. Although there is a lack of bituminous argillaceous Eramosa lithofacies within core, the laminated Eramosa Member is thick near Wiarton which suggests that a large restricted less-oxygenated area existed in that vicinity during the Silurian. Thick accumulations of tan-brown fossiliferous undifferentiated Guelph Formation dolostones occur at both the northern and southern ends of the Peninsula.
Petrographic analyses reveal that the Amabel and Guelph formations are dolomitized with no precursor limestone observed. Four types of dolomite were observed within these formations and differentiated based on crystal size. These dolomites are characterized by a uniform dull red luminescence, and range from inclusion-rich anhedral very finely (< 5 µm) crystalline dolomite to clearer euhedral coarsely (> 250 µm) crystalline dolomite. Petrographic analyses also revealed secondary minerals such as pyrite, calcite (and dedolomite), silica, sphalerite, fluorite, and glauconite.
Ground-penetrating radar surveys provided high-resolution data, which combined with detailed geologic observations of accessible quarry outcrops and borehole logs, support the conclusion that GPR is a useful tool for locating karstic features, vuggy porosity, and lateral and vertical facies changes in carbonate rocks. Radar profiles may have important implications for the aggregate and building-stone industries as a tool to locate carbonate units of exploration interest or to avoid zones with high impurities.

Повний текст джерелаA Mesoproterozoic basement and a Cambrian-Ordovician carbonate platform characterize the Precordillera terrane. These characteristics and its distinct geologic history mark a difference between this suspected exotic-to-Gondwana terrane and the Gondwanan autochthonous, leading to speculation that the Precordillera was derived from Laurentia. The surprising similarities of the carbonate sequences between the Precordillera and certain parts of southeast Laurentia suggest a common geological history. However, other models interpret the origin of the Precordillera terrane as being para-autochthonous with respect to Gondwana. All these models are still controversial. A combination of several methodologies including petrography and heavy minerals analysis, geochemistry, Sm-Nd and Pb-Pb isotopes and zircon dating were applied to several Ordovician and Ordovician to Silurian units of the Precordillera terrane. Geochemistry and petrography indicates that all the Formations studied have similar characteristics, with at least two sources providing detritus to the basin. The dominant source has an unrecycled upper continental crust composition whereas the other component is more depleted. The study of detrital chromian spinels suggests that mid-ocean ridge basalts, continental intraplate flood basalts and ocean island basaltrelated rocks were among the sources for the detrital record of the Precordillera terrane. Nevertheless, the mafic sources and their ages remain unknown. Nd isotopes account for negative εNd values and TDM ages in a range of variation found elsewhere within Gondwana and basement rocks of the Precordillera. The Sm/Nd ratios of certain samples indicate fractionation of LREE. Pb isotopes indicate that a source with high 207Pb/204Pb was important, and point to Gondwanan sources. Detrital zircon dating constrain the sources as being dominantly of Mesoproterozoic age (but with a main peak in the range 1.0 to 1.3 Ga), with less abundant populations of Neoproterozoic (with a main peak in the range 0.9 to 1.0 Ga), Palaeoproterozoic, Cambrian and Ordovician ages in order of abundance. i The uniformity shown by the provenance proxies indicate that there were no important changes in the provenance from the Lower Ordovician until the Early Silurian. Several areas are evaluated as sources for the Precordillera terrane. The rocks that fit best all the provenance constraints are found within the basement of the Precordillera terrane and the Western Pampeanas Ranges. Basement rocks from the Arequipa-Antofalla area (Central Andes) also match the isotopic characteristics, but a northern source is less probable, except for the Western tectofacies. On the other hand, areas such as Antarctica, Falklands/Malvinas Microplate, the Natal-Namaqua Metamorphic belt and the Grenville Province of Laurentia can be neglected as sources. The proposal of these areas as sources is in agreement with palaeocurrents and facies analyses and suggests proximity between them and the Precordillera since at least the Late Arenig to Early Llanvirn. This has important implications for the proposed models regarding the geotectonic evolution of the Precordillera terrane. The models would need to be adjusted to the here proposed youngest timing of collision.
