Propagação in vitro e in vivo de Hippeastrum aulicum (Ker-Gawler) Herb. (Amaryllidaceae)
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências Agrárias. Programa de Pós-Graduação em Recursos Genéticos Vegetais.O Brasil é um país rico em espécies de plantas nativas com potencial ornamental. No entanto, o pouco conhecimento das espécies e a falta de um sistema de propagação adequado têm limitado a utilização das mesmas na floricultura. Hippeastrum aulicum (Ker-Gawler) Herb (Amaryllidaceae) é uma espécie nativa da Mata Atlântica, cujo valor comercial é reconhecido em outros países, mas é praticamente desconhecido no Brasil. Não foram encontrados trabalhos sobre a propagação da espécie, no entanto, em casa de vegetação, observou-se que são produzidos poucos bulbos por planta, inviabilizando a multiplicação natural como método de propagação em escala comercial. Neste contexto, este trabalho teve como objetivo analisar metodologias para a propagação da espécie Hippeastrum aullicum, através da germinação das sementes, estaquia de bainhas foliares, micropropagação de segmentos de partes florais e de bainhas foliares e indução de calos em embriões imaturos e em segmentos de plântulas in vitro. Os resultados destes estudos indicaram que as sementes de H. aulicum possuem elevado potencial germinativo, atingindo 100% de sementes germinadas, quando semeadas em ambiente com ausência de luz e em temperaturas de 25-35 oC. Na estaquia de bainhas foliares verificou-se que não é necessária a utilização de ANA ou AIB para o enraizamento das mesmas e as estacas retiradas da região central do bulbo são mais indicadas como material para estaquia. Explantes de dupla camada de bainhas foliares foram mais adequados que explantes de partes florais para a micropropagação devido à elevada oxidação in vitro dos últimos. Com a utilização de 1 µM ANA e 4µM BAP foram obtidos os melhores resultados para indução de brotações e bulbos nos explantes de bainhas foliares. Com a utilização de 4 µM ou 10 µM de 2,4-D e explantes de seções proximais de sementes com embriões com menos de 1 mm de comprimento foram obtidas as maiores porcentagens de embriões com calos friáveis

Physical volcanology and geochemistry of the lower Gawler Range Volcanics in the southern Gawler Ranges
No full textThis item is only available electronically.The Gawler Range Volcanics are a Silicic Large Igneous Province that has been extensively studied due to the atypical nature of its widespread felsic lava flows. These low viscosity lavas form the upper sequence of the GRV, termed the Upper Gawler Range Volcanics (UGRV). The older sequence or Lower Gawler Range Volcanics (LGRV) are readily distinguished from the UGRV as they appear as numerous discrete volcanic centres, the best exposed of which are at Kokatha and Lake Everard. A much less discussed volcanic area of the LGRV are the Southern Gawler Ranges Area Volcanics (SGRAV), which form a curvilinear belt along the southern margin of the GRV. The SGRAV are dominantly represented by two volcanic units, the Bittali Rhyolite (BR) and Waganny Dacite (WD) which are exposed discontinuously for ~200km E-W. The SGRAV may be divided into a western section of dominantly effusive volcanism, with elevated temperatures and halogen contents comparable to that of the UGRV, and a central-eastern section where explosive volcanism predominates. Petrogenetic modelling suggests that assimilation fractional crystallization (AFC) processes which played a role in the development of the LGRV, were active in the formation of the SGRAV. However, using AFC modelling, the SGRAV can be reconstructed through a dominant fractional crystallization process with late stage crustal assimilation, as opposed to continual crustal assimilation in the other LGRV magma systems.Thesis (B.Sc.(Hons)) -- University of Adelaide, School of Physical Sciences, 201

Characterization and potential toxicity of asbestiform erionite from Gawler Downs, New Zealand
No full textErionite is the name for a zeolite mineral series originating from diagenesis or hydrothermal alteration of volcanic rocks. The particular erionite "species"is based on the dominant extra-framework cation, erionite-Ca, erionite-K, or erionite Na. Irrespective of the species, erionite can display a fibrous/ asbestiform morphology and has been linked with cases of malignant mesothelioma, a disease typically associated with asbestos exposure. Characterization of new discoveries of erionite is therefore important to assess any potential exposure hazards. This study describes a new asbestiform erionite from vesicles within the Upper Cretaceous Mt. Somers Volcanics Group (MSVG), Canterbury, New Zealand. The erionite is within the Hinds River Dacite, the youngest unit within the MSVG at Gawler Downs, ~100 km west of Christchurch, in the foothills of the Southern Alps. A multi-analytical approach was taken to analyze the sample which included micro-Raman spectroscopy, thermogravimetric analysis, electron microscopy, electron microprobe analysis, and X-ray powder diffraction with the Rietveld method. Results confirmed the mineral as fibrous erionite-K. The chemical composition of the mineral is unique due to the presence of higher levels of Mg. While Fe was also identified, this was due to smectite flakes occurring on the surface of the erionite fibers. According to the World Health Organization (WHO) respirable mineral fiber definition, where length ≥5 μm. width ≤3 μm, and aspect ratio (L/w) ≥3:1, the Gawler Downs erionite fibers are respirable, while the fibers themselves exceed respirable thickness. In addition to morphology. a value for the potential toxicity model was computed to be 2.28 for the Gawler Downs erionite. This is similar to those of other carcinogenic erionites from Karain. Turkey (2.33). and Nevada. U.S.A. (2.28). Taken together. results indicate Gawler Downs erionite represents an environmental hazard. Nevertheless. further investigation is required to determine potential environmental exposure pathways by which erionite may become airborne and assess the actual environmental risk in the Gawler Downs area

Mesoarchean to Mesoproterozoic evolution of the southern Gawler Craton, South Australia
No full textThe Gawler Craton preserves a complex and prolonged tectonic history spanning the interval c. 3200-1500 Ma. Reworking of Paleoarchean, c. 3400-3250 Ma crust led to the formation of c. 3150 Ma granites now exposed within a narrow belt in the eastern Gawler Craton. Following this, there is no known record of significant tectonic activity until the onset of bimodal magmatism during the Neoarchean to earliest Paleoproterozoic, c. 2560-2470 Ma. This magmatism was terminated by high temperature metamorphism and deformation during the 2465-2410 Ma Sleafordian Orogeny. Magmatic events associated with widespread sedimentation over the interval c. 2000-1740 Ma largely sources this older crust. The c. 1730-1690 Ma Kimban Orogeny reworked these Paleoproterozoic basins and the Neoarchean basement in a pre-dominantly transpressional orogenic system. Juvenile mantle input followed by widespread crustal melting occurred over the interval c. 1620-1570 Ma. This period of intense magmatism initiated with emplacement of the relatively juvenile c. 1620-1608 Ma St Peter Suite. This was followed by the economically significant c. 1600-1570 Ma Gawler Range Volcanics/Hiltaba Suite magmatic event, which resulted from widespread mid-crustal melting. Synchronous deformation and high temperature metamorphism accompanied the Gawler Range Volcanics/Hiltaba Suite magmatic event indicating it occurred in an orogenic environment. Far field stress was distributed around a central core zone of largely undisturbed Gawler Range Volcanics with deformation localised in the northern and southern Gawler Craton. The Gawler Range Volcanics/Hiltaba Suite magmatic event resulted in formation of a province of major economic significance that includes the giant Olympic Dam Cu-Au-U ore body.Anthony J.
