  • Basaltic Macadam-Breccias in the Girvan-Ballantrae Complex, Ayrshire
    Downloaded from http://sjg.lyellcollection.org/ at University of Nairobi, Kenya on April 12, 2016 Basaltic macadam-breccias in the Girvan-Ballantrae Complex, Ayrshire A. D. LEWIS1 and T. W. BLOXAM2 department of Geology, University of Nairobi, Nairobi, Kenya ^Department of Geology, University College, Swansea SYNOPSIS Many supposed "volcanic agglomerates and tuffs" in the Girvan-Ballantrae complex of southern Ayrshire are considered to be non-pyroclastic in origin. These macadam breccias are accumulations of lava breccia derived mainly from the autoclastic disintegration of pillow basalts during, or shortly after, extrusion. The breccia-forming process is considered to be mainly a func­ tion of supercooling, glass formation and retention of volatiles, all of which are directly related to external hydrostatic pressure. INTRODUCTION Throughout the Girvan-Ballantrae igneous complex of southern Ayrshire a group of fragmental rocks, generally referred to as "volcanic breccia, agglomerate and tuff" (Peach and Home 1899; Geol. Surv. Scotland, 1" sheet 7), are closely associated with Ordovician basaltic pillow lavas. The most extensive exposures of these particular volcaniclastic rocks occur on Knockdolian and Sallachan Hills [NX 113 848; NX 128 848] about three kilometres north-east of Ballantrae; around Knockormal Hill [NX 132 881]; Lochton Hill [NX 133 875]; Carleton Hill [NX 128 893] and on the coast at Pinbain [NX 137 916] (Fig. 1). The most extensive exposures on Knockdolian Hill have been briefly mentioned by Pringle (1948, p. 11) who notes that these "agglomerates and breccias" are unusual in ". the absence of any fine-grained matrix, the rock being composed of angular fragments of a vesicular lava presenting the appearance of consolidated macadam".

  • Wandervorschlag: Die Wanderung Entlang Der Wesenitz
    Wandervorschlag: Die Wanderung entlang der Wesenitz Von der Quelle bis zur Mündung - Aus dem Granit durch den Sandstein in die Elbe Wandervorschlag von Roland Füssel, Helmsdorf Die Wesenitzquelle befindet sich im Granit des Hohwaldgebietes der Oberlausitz zwischen Neustadt in Sachsen, Steinigtwolmsdorf und Neukirch/Lausitz. Sie entspringt in 515 m über NN am Südhang des Valtenberges und mündet nach ca. 71 km bei Pratzschwitz in die Elbe. Dabei durchfließt sie bzw. berührt mit ihrem Lauf etwa 25 Ortschaften. Ihr Name stammt aus dem sorbischen und bedeutet „Bach der Ulme“. Mit der Wasserkraft wurden in der Vergangenheit über 100 Mühlen, Sägewerke und Schleifen betrieben. Heute existieren davon nur noch wenige, wurden zum Teil umgebaut oder sind dem Verfall preisgegeben. Gegenwärtig gibt es einige Objekte, die mit eingebauten Turbinen Strom erzeugen. Für die Wanderung bietet sich die Topographische Karte Blatt 42, 43 und 48 des Landesvermessungsamtes Sachsen an. Es steht eine verkehrsberuhigende Streckenführung im Vordergrund. Er führt mehr oder weniger direkt an der Wesenitz entlang. Bitte beachten Sie, dass die Strecke teilweise durch Naturschutzgebiete verläuft. An der Wesenitz lässt es sich zu jeder Jahreszeit gut wandern, außer bei Hochwasser. Zum Valtenberg gelangen wir u.a. von Neustadt in Sachsen (markierter Wanderweg blauer bzw. roter Strich) oder von Neukirch/Lausitz (grüner Strich) aus. Eine Bushaltestelle befindet sich an der Hohwaldschänke und auf markiertem Weg ist die Quelle nach ca. 3 km nicht sehr weit. Der Quellort, ein alter Stollen, im Volksmund auch als „Goldbergwerk“ bekannt, ist der Ausgangpunkt zum naheliegenden Gipfel des Valtenberges, mit der Baude (Gaststätte) und dem 22 m hohen Turm. Er bietet einen guten Rundblick in die Oberlausitz, das Zittauer Gebirge, ins Isergebirge, in die Sächsische Schweiz und dem Osterzgebirge.

The advancements in computer technology and data availability have assisted their rapid development and wide use. This project aims to evaluate the applicability of a physically based, fully distributed rainfall-runoff model TOPKAPI-X for the simulation of flood events in two small watersheds of Saxony, Germany. The 2 results indicate that the model was calibrated well for 4.88 km Wernersbach catchment (NSE 0.89), whereas 276 km2 Wesenitz catchment calibration was only satisfactory (NSE 0.7). The addition of the Citation: Janabi, F.A.; Ongdas, N.; second soil layer improved the model’s performance in comparison to the simulations with only one Bernhofer, C.; Reyes Silva, J.D.; soil layer for Wernersbach (NSE increase from 0.83 to 0.89).

HOLIDAY HIGHLIGHTS Walk the 70 mile romantic Malerweg (Painters Trail). Visit Europe’s largest freestanding rock arch. Experience a glorious display of contrasting and breathtaking landscapes. Visiting two wonderful contrasting cities. BOHEMIAN RHAPSODY Through woods rich in ferns and mosses, across meadows, up fissures between pillars of eroded sandstone, the Malerweg, or Painters' Way, winds its way through Germany's Saxon Switzerland. From rocky viewpoints the meandering Elbe is often visible. You first see the river beneath Prague's Charles Bridge, where it is known as the Vltava. At the end of our journey you meet it once again in the neo-classical and Baroque splendour of Dresden. We follow the Malerweg in its entirety from our riverside base in Krippen adjacent to the resort of Bad Schandau. Throughout the trail's seventy miles, which we follow in eight stages, it is easy to see why great painters and musicians have found inspiration here. The unique jumble of rocks, the sweeping panoramas, the dampness of the forest floor, mists rising from the valleys; these are the very essence of the Romantic Movement.

  • On the Variolitic Structure
    On the variolitic structure. By Harald Carstens Abstract. The article presents detailed descriptions of the variolitic structure in selected minor intrusions and lavas. The evidence indicates that the varioles formed by liquid segrega tion rather than by spherulitic crystallization. Introduction. The commonly accepted opinion on the origin of varioles is reflected in modem petrographic textbooks which traditionally state that the variolitic structure of basic igneous rocks is equivalent to the spherulitic structure of silicious lavas and intrusions, which are presumably formed by rapid crystallization in a viscous magma or by devitrification of glass around scattered nuclei. The spheroidal shape of varioles by this hypo thesis is thus accounted for by the crystallization of one mineral from numerous centers with equal velocity in all directions. A number of observations presented below are, however, inconsistent with this view. Petrographic literature of this century conveys the impression that varioles are a structural curiosity. This is probably not so. Studies of minor intrusions and lavas from Norway have shown that in certain rocks this structure exists almost invariably. Certain types of lamprophyres and spilitic pillow lavas are particularly prone to a variolitic development. The variolitic structures of some Norwegian rocks, one monchiquite, a few vogesites, and a glassy augitite lava, are described below. The Nor wegian pillow lavas are altered and not suitable for detailed treatment. 27 Minor intrusions. a) Monchiquite dyke, Hamar The dyke is exposed in a limestone quarry at Furuberget about 3 km north of Hamar. The dyke is obviously connected with the Permian volcanism of the Oslo region and has intruded into a Middle Ordovician limestone.

  • Geochemistry of Archaean Volcanic Rocks from Iron Ore Supergroup, Singhbhum, Eastern India
    Geochemistry of Archaean volcanic rocks from Iron Ore Supergroup, Singhbhum, eastern India S SENGUPTA*, S K ACHARYYA*, J B DESMETH** * Geological Survey of India, 27, Jawaharlal Nehru Road, Calcutta 700016 ** ITC, Kanaalweg 3 2628EB, Delft, The Netherlands Mafic-ultramafic rocks of Archaean age constitute a significant component of the Eastern Indian Craton. These occur in two different modes. In the eastern belt these occur as a long, linear enclave within the Singhbhum granite and the primary banding in them is subvertical. In the more extensive western belt along the periphery of the Singhbhum granite, the disposition of the primary banding is subhorizontal. The major rock type in both the belts is meta-basalt with minor peridotitic komatiite and basaltic komatiite occurring in the eastern belt. Rare ultramafic rocks with cumulate textures are present in both the belts. The larger volume of the basaltic rocks preclude the possibility of their being derived by fractional crystallization of the high-MgO components. On the basis of trace element and REE characters the rocks may be classified into three groups. One of the groups shows a tholeiitic trend and include samples mostly from the eastern belt while the second consisting mostly of samples from the western belt shows a calc-alkaline trend. The third group includes samples having elemental ratios intermediate between these two groups. Zr/Nb ratios for the tholeiitic and calc-alkaline samples are different suggesting their sources to be different. The tholeiitic samples have been generated from a source having chondritic REE characters, while the calc-alkaline samples have been generated from a source with LREE enriched character.

  • The Metamorphism of the Cambrian Basic Volcanic Rocks of Tasmania and Its Relationship to the Geosynclinal Environ­ Ment
    PAPlilllS AND PROCEEDINGS OF THE ROYAL SOCI>lTY OF TASMANIA, VOLUMB 88 The Metamorphism of the Cambrian Basic Volcanic Rocks of Tasmania and its Relationship to the Geosynclinal Environ­ ment By BERYL SCOTT, B.SC., PH.D. (With 4 Plates and 2 Text Ji'igwres) ABSTRACT A spilitic suite comprising picrite basalts, spilites, keratophyres, albite dolerites and associated pyroclastics of Middle and Upper Cambrian age, outcrops on the North-Vi/est and West Coast of Tasmania. The spilites and keratophyres are considered to have been normal basalts which later suffered soda metasomatism as a result of geosynclinal depOl::,ition and orogeny. Hydrothermal alteration of the volcanics has also given rise to a variety of other rock types which includes porphyries, variolite, spherulitic quartz rock and jasper. INTRODlJCTION While the author was resident in Tasmania, a detailed petrographie study was made of the Cambrian volcanle rocks of the State and the results were submitted to the University of Tasmania as a thesis for the degree of Doctor of Philosophy in 1952. Several papers have already been published on this work (Scott, 1952), but after leaving Tasmania it was thought necessary to publish a general summary of the whole study even though the interpretations may not be eonelusive. Mueh confusion exists in the literature dealing with the volcanics of the 'Vest Coast of Tasmania. The igneous rocks have been referred to as porphyroids, keratophyres, quartz and feldspar porphyries, andesites, melaphyres and syenites. The present author believes that the greater part of the volcanics was essentially basic in composition, probably basalts and porphyritic basalts, with or without amygdales, and their corresponding pyroclastics.
