  • A K-Feldspar Breccia from the MO-Cu Stockwork Deposit in the Galway Granite, West of Ireland
    Journal ofthe Geological Sociefy, London, Vol. 145, 1988, pp. 661-667, 4 figs, 2 tables. Printed in Northern Ireland A K-feldspar breccia from the MO-Cu stockwork deposit in the Galway Granite, west of Ireland J. M. DERHAM & M. FEELY Department of Geology, University College, Galway, Ireland Abstrart: A K-feldspar breccia, spatially associated with the MO-Cu mineralization of a stockwork in the Late Caledonian Galway Granite at Mace Head, is described for the first time. Detailed mapping reveals a network of breccia pods and veins over an area of approximately 6000 m’. The breccia is clast-supportedand is composed of sub-angular fragments of perthiticK-feldspar megacrysts (<10cm), granite and microgranodiorite clasts (<25 m) set in a matrix of quartz (<l cm), biotite (<5 cm) and apatite (<3 mm). Field and textural studies indicated that the feldspar megacrysts and granite clasts were brecciated and silicified as they were carried (to the present structural level) by hydrous K- and Si0,-rich fluids. The residue of these fluids crystallized to form the breccia matrix. The formation of the breccia predates the mineralized quartz veins of the MO-Cu stockwork. It is concluded that the breccia formation is genetically related to ore-forming processes in the Galway Granite. Breccia lithologies with a wide spectrum of characteristics of the batholith.

  • Magmatism and the Baraboo Interval: Breccia, Metasomatism, and Intrusion
    MAGMATISM AND THE BARABOO INTERVAL: BRECCIA, METASOMATISM, AND INTRUSION by J.K. Greenbergl. ABSTRACT Breccia consisting of quartzite fragments surrounded by wh ite, vein quartz is known to occur in Wisconsin at several exposures of Baraboo-type metasedimentary rock. These quartzite breccias include those at Rock Springs on the north limb of the Baraboo Syncline, Hamilton Mound. Necedah, Battle Point, Vesper, Waterloo , and McCaslin Mountain. with the exception of McCaslin Mountain in the northeast, all the breccias occur in the central or south-central part of the state. Most of the brecciated quartzite has intrusive contact with plutonic rock. Various types of hydrothe�al alteration (metasomatism) are apparent in the brecciated outcrop and other exposures of quartzite intruded by granitic or dioritic magma . The most common metasomatic features are quartz crystal­ lined pockets and clay-mica segregations , feldspar porphyroblasts in altered quartz ite , hematite segregations , and quartz-tourmaline veinlets . A present interpretation of the breccias is that they are analogous to the stockwork of quartz veins produced around the upper levels of porphyry- copper mineralized plutons. During mag­ ma intrusion, the roof rock of quartzite was fractured and soaked in hyd rous granitic fluids. The fluids and their particular effects vary with distance from source plutons . Thus, as in some Wis­ consin examples quartz veins and breccia grade into pegmatite dikes as an intrusion is approached . Another possible analogue for the Wisconsin examp les are explosive breccias developed in quartzite above volatile-rich appinite intrusions . INTRODUCTION Several exposures of quart zite deposited during the Proterozoic Baraboo tectonic interval (Dott, 1983; Greenberg and Brown , 1983, 1984) contain breccia with a white vein·-quartz matrix.

Gardewegb aDepartment of Earth Sciences, University of Bristol, Bristol BS8 1RJ, UK bServicio Nacional de Geologia y Mineria, Avenida Santa Maria 0104, Casilla 10465, Santiago, Chile Received 4 November 1998; revised and accepted 4 May 2000 Abstract Investigations have been made on the distribution of pumice and lithic clasts in the lithic rich Soncor ignimbrite (26.5 ka) and the 1993 pumice ¯ow deposits of Lascar Volcano, Chile. The Soncor ignimbrite shows three main lithofacies which grade into one another. Coarse lithic breccias range from matrix poor strati®ed varieties, irregular shaped sheets and elongate hummocks in proximal environments, to breccia lenses with pumiceous ignimbrite matrix. Massive, lithic rich facies comprise the bulk of the ignimbrite. Pumice rich facies are bimodal with abundant large pumice clasts (often with reverse grading), rare lithic clasts and occur distally and on high ground adjacent to deep proximal valleys. In the 1993 pyroclastic ¯ow deposits lithic rich facies are deposited on slopes up to 148 whereas pumice rich facies are deposited only on slopes ,48. Lithic rich parts show a thin pumice rich corrugated surface which can be traced into the pumice rich facies. The high lithic content in the Soncor ignimbrite is attributed to the destruction of a pre-existing dome complex, deep explosive cratering into the interior of the volcano and erosion during pyroclastic ¯ow emplacement.

  • A Fluidization Breccia in Granite at Skaget, Svellingen, Frøya
    A Fluidization Breccia in Granite at Skaget, Svellingen, Frøya TORE TORSKE Torske, T. 1983: A fluidization breccia in granite at Skaget, Svellingen, Frøya. Norges geol. Unders. 380, 107-123. The breccia consists of fragmented and comminuted host rock material and small amounts of hydrothermal quartz, epidote, laumontite, ?stilbite, calcite and montmo rillonite. At least three brecciation and mineralization events have occurred. The breccia is considered to have formed by hydraulic fracturing by a mixed, high-pres sure CO2-H2O fluid. Upon explosive venting to the surface, the fluid is thought to have fluidized and fragmented the fractured rock. The carbon dioxide of the fluid may have originated in the mantle, and could have ascended through the crust by hydraulic fracture propagation. It is suggested that the occurrence within the same region of the Skaget Breccia, Tertiary olivine-nephelinite plugs, and scattered zeolite mineralization may possibly define a palaeo-geothermal province. Tore Torske, Institutt for Biologi og Geologi, Universitetet i Tromsø, Postboks 3085, N-9001 Tromsø, Norway. Introduction A small breccia body cutting through granite at Skaget, Svellingen, Frøya (UTM co-ordinates NR 912752; Fig. 1) was described by Keilhau (1850) and mentioned by Reusch (1914), but has not been treated in newer literature. It occupies the tip of a small, pointed headland called Skaget (Figs 2 & 3). On land, the Skaget Breccia covers about 5000 m 2, but is surrounded by the sea on three sides; accordingly, its full extent and shape are unknown. In addition to the main breccia outcrop, there are a few, scattered, small occurrences of breccia over a distance of a couple of hundred metres southward along the coast.

  • Glossary of Geological Terms
    GLOSSARY OF GEOLOGICAL TERMS These terms relate to prospecting and exploration, to the regional geology of Newfoundland and Labrador, and to some of the geological environments and mineral occurrences preserved in the province. Some common rocks, textures and structural terms are also defined. You may come across some of these terms when reading company assessment files, government reports or papers from journals. Underlined words in definitions are explained elsewhere in the glossary. New material will be added as needed - check back often. - A - A-HORIZON SOIL: the uppermost layer of soil also referred to as topsoil. This is the layer of mineral soil with the most organic matter accumulation and soil life. This layer is not usually selected in soil surveys. ADIT: an opening that is driven horizontally (into the side of a mountain or hill) to access a mineral deposit. AIRBORNE SURVEY: a geophysical survey done from the air by systematically crossing an area or mineral property using aircraft outfitted with a variety of sensitive instruments designed to measure variations in the earth=s magnetic, gravitational, electro-magnetic fields, and/or the radiation (Radiometric Surveys) emitted by rocks at or near the surface. These surveys detect anomalies. AIRBORNE MAGNETIC (or AEROMAG) SURVEYS: regional or local magnetic surveys that measures deviations in the earth=s magnetic field and carried out by flying a magnetometer along flight lines on a pre-determined grid pattern. The lower the aircraft and the closer the flight lines, the more sensitive is the survey and the more detail in the resultant maps. Aeromag maps produced from these surveys are important exploration tools and have played a major role in many major discoveries (e.g., the Olympic Dam deposit in Australia).
