Bailey GEOLOGIC SETTING VOLCANISM Long Valley caldera and the Mono-Inyo Craters Long Valley caldera volcanic chain compose a late Tertiary to Quaternary Volcanism in the Long Valley area (Bailey and others, volcanic complex on the west edge of the Basin and 1976; Bailey, 1982b) began about 3.6 Ma with Range Province at the base of the Sierra Nevada frontal widespread eruption of trachybasaltic-trachyandesitic fault escarpment. The caldera, an east-west-elongate, lavas on a moderately well dissected upland surface oval depression 17 by 32 km, is located just northwest (Huber, 1981).Erosional remnants of these mafic lavas of the northern end of the Owens Valley rift and forms are scattered over a 4,000-km2 area extending from the a reentrant or offset in the Sierran escarpment, Adobe Hills (5-10 km notheast of the map area), commonly referred to as the "Mammoth embayment.'? around the periphery of Long Valley caldera, and The Mono-Inyo Craters volcanic chain forms a north- southwestward into the High Sierra.

    Bertini et al. DEEP DRILLING RESULTS AND UPDATING OF GEOTHERMAL KNOWLEDGE ON THE MONTE AMIATA AREA Giovanni Bertini, Guido Cappetti, Ivano Dini, Lovari ENEL - Via 120,56122 Pisa, Italy Key words: Geothermal exploration, Gravimetric anomaly, Intrusion, Based on experience gained from deep drilling in the Larderello Neogene Seismic horizon, Thermal anomaly, field, the research in the Monte Amiata area was resumed in 1978: Thermometamorphic rock. two deep exploratory wells were drilled in the Bagnore and Piancastagnaio fields to find additional fluid below the layers already ABSTRACT under exploitation. Both wells turned out to be productive and led to the implementation of a deep drilling program. Deep geothermal exploration begun in Bagnore and Piancastagnaio geothermal fields in the late has led to the discovery of a deep water-dominated reservoir with a temperature of and a pressure of 20-25 In the Piancastagnaio field 24 wells have been drilled, with a success ratio of about 90% and an average specific productivity of about 4 MW per well. Three 20 MW power plants are in operation, one is presently under construction and will be on line in 1995, and another three are be installed. In the Bagnore field seven wells have been drilled to assess the resource. In this area too the results were positive: it is planned to drill 13 wells and build three 20 MW power plants. The geological and geophysical data have been reconsidered and the structural features of the geothermal reservoir have been reconstructed. A recent granitic intrusion (the probable source of the Monte Amiata thermal anomaly) has been hypothesized at a depth of 7 km over a much wider area than previously believed.

  • Summary of the Mineral Information Package for the Khanneshin Carbonatite Area of Interest
    Chapter 21A. Summary of the Mineral Information Package for the Khanneshin Carbonatite Area of Interest Contribution by Robert D. Tucker, Harvey E. Belkin, Klaus J. Schulz, Stephen G. Peters, and Kim P. Buttleman Abstract The Khanneshin carbonatite is a deeply dissected igneous complex of Quaternary age that rises approximately 700 meters above the flat-lying Neogene sediments of the Registan Desert, Helmand Province, Afghanistan. The complex consists almost exclusively of carbonate-rich intrusive and extrusive igneous rocks, crudely circular in outline, with only three small hypabyssal plugs of leucite phonolite and leucitite outcropping in the southeastern part of the complex. The complex is broadly divisible into a central intrusive vent (or massif), approximately 4 kilometers in diameter, consisting of coarse-grained sövite and brecciated and agglomeratic barite-ankerite alvikite; a thin marginal zone (less than 1 kilometer wide) of outwardly dipping (5°–45°). Neogene sedimentary strata; and a peripheral apron of volcanic and volcaniclastic strata extending another 3–5 kilometers away from the central intrusive massif. Small satellitic intrusions of biotite-calcite carbonatite, no larger than 400 meters in diameter, crop out on the southern and southeastern margin of the central intrusive massif. In the 1970s several teams of Soviet geologists identified prospective areas of interest for uranium, phosphorus, and light rare earth element (LREE) mineralization in four regions of the carbonatite complex. High uranium concentrations are reported in two regions; the greatest concentrations are confined to silicified shear zones in sandy clay approximately 1.1 kilometers southwest of the peripheral part of the central vent. An area of phosphorus enrichment, primarily occurring in apatite, is present in coarse-grained agglomeratic alvikite, with abundant fenite xenoliths, approximately 750 meters south of the periphery of the central vent.

  • Geothermal Springs, Geysers and Fumaroles
    Sciences Secondary volcanic activities: Geothermal springs, Geysers and Fumaroles Geothermal Springs A geothermal (or hydrothermal) spring is produced by the emergence of geothermally heated groundwater from the Earth's crust. There are geothermal springs in many locations all over the crust of the earth. Geothermal Springs Surface water percolates downward through the rocks below the Earth's surface to high-temperature regions surrounding a magma chamber, either active or recently solidified but still hot. When the water is heated, becomes less dense, and rises Surface water back to the surface along fissures and cracks. Sometimes these features are called "dying volcanoes" because they seem to represent the last stage of volcanic activity as the magma, in depth, cools and hardens. Water percolation Heated water rises up The temperature of hot springs depends on factors such as: •the rate at which water circulates through the underground channels Hot rocks •the amount of heat at depth •the dilution of the heated water by cool ground water near the surface. Geothermal Springs The water issuing from a hot spring is heated by geothermal heat from the Earth's astenosphere. In general, the temperature of rocks increases with depth. The rate of temperature increase is known as the geothermal gradient (it is about 25°C per km). If water percolates deeply enough into the crust, it will be heated as it comes into contact with hot rocks. Warm springs are sometimes the result of hot and cold springs mixing but may also occur outside of volcanic areas. Geysers Geyser are located near active volcanic areas, and the geyser effect is due to the proximity of magma.

As a result of the work, the deformation scales and ages of the geological processes at the Neo-Archaean–Paleoproterozoic stage of the area’s development were compiled, and the reference rocks were dated. The petrochemical and geochemical characteristics of the Ingozero rocks are similar to those of tonalite–trondhjemite–granodiorite (TTG) complexes established on other Archaean shields. The isotope U–Pb dating of individual zircon grains from the biotite gneisses provided the oldest age for magmatic protolith of the Ingozero gneisses, which is 3149 46 Ma. Sm–Nd model ages showed that the gneisses protolite initial melt formed at 3.1–2.8 Ga. ± Ages of metamorphic processes were determined by using isotope U–Pb dating ID TIMS (isotope dilution thermal ionization mass spectrometry): Biotite gneisses—2697 9 Ma; amphibole–biotite ± gneisses—2725 2 Ma and 2667 7 Ma; and biotite–amphibole gneisses 2727 5 Ma.

  • Geomorphological Evolution of Phlegrean Volcanic Islands Near Naples, Southern Italy1
    Berlin .Stuttgart Geomorphological evolution of Phlegrean volcanic islands near Naples, southern Italy1 by G.AIELLO, D.BARRA, T.DE PIPPO, C.DONADIO, and C.PETROSINO with 9 figures and 5 tables Summary. Using volcanological, morphological, palaeoecological and geoarchaeological data we reconstructed the complex evolution of the island volcanic system of Procida-Vivara, situated west of Naples betweenthe lsland of lschia and the PhlegreanFields, far the last 75 ky. Late Pleistocenemorphological evolution was chiefly controlled by a seriesof pyroclas­ tic eruptions that resulted in at least eight volcanic edifices, mainly under water. Probably the eruptive centresshifted progressively clockwise until about 18 ky BP when volcanic develop­ ment on the islands ceased. The presenceof stretches of marine terraces and traces of wave cut notches, both be­ low and abovè'current sea levels, the finding of exposed infralittoral rnicrofossils, and the identification of three palaeo-surfacesburied by palaeosoilsindicates at least three differen­ tial uplift phases.These phases interacted with postglacial eustaticfIuctuations, and were sep­ arated by at least two periods of generai stability in vertical movements. A final phase of ground stability, characterisedby the deposition of Phlegrean and lschia pyroclastics, start­ ed in the middle Holocene. Finally, fIattened surfacesand a sandy tombolo developedup to the present-day. Recent archaeological surveys and soil-borings at Procida confirm the presence of a lagoon followed by marshland at the back of a sandy tombolo that were formed after the last uplift between the Graeco-Roman periodandthe15di_16dicentury. These areaswere gradu­ ally filled with marine and continental sedimentsup to the 20di century. ' Finally, our investigation showed that the volcanic sector of Procida-Vivara in the late Pleistocene-Holocenewas affected by vertical displacementswhich were independent of and less marked than the concurrent movement in the adjacent sectors of lschia and of the Phle­ grean Fields.

  • Hydrovolcanic Vs Magmatic Processes in Forming Maars and Associated Pyroclasts: the Calatrava -Spain- Case History
    1 Hydrovolcanic vs Magmatic Processes in Forming Maars and Associated Pyroclasts: The Calatrava -Spain- Case History F. Stoppa, G. Rosatelli, M. Schiazza and A. Tranquilli Università Gabriele d'Annunzio, Dipartimento di Scienze, Chieti Italy 1. Introduction The Calatrava Volcanic Field (CVF) of Castilla-La Mancha is characterised by numerous monogenetic volcanic centres, that erupted mainly foidites, melilitites and carbonatites (ultra-alkaline rock-association sensu, Le Bas, 1981) carrying abundant mantle xenoliths. At CVF, carbonatites have been described by Bailey et al. (2005) and Stoppa et al. (2011). Along with the volcanic field of Eifel of Germany, Limagne basin of France and Intra-mountain Ultra-alkaline Province (IUP) of Italy, the CVF encompasses the most numerous Pliocene- Quaternary extrusive carbonatites in Western Europe in terms of dimension, number and size of volcanoes (Bailey et al., 2005; Bailey et al., 2006). Similar volcanic fields are Toro- Akole and Bufumbira in Uganda (Bailey & Collier, 2000), the Avon district in Missouri (Callicoat et al., 2008), Mata da Corda in Brazil (Junqueira-Brod et al., 1999) and West Qinling in Gansu Province, China (Yu et al., 2003). In spite of abundant local studies (González Cárdenas et al., 2010; Peinado et al., 2009), the CVF has been mostly neglected by the international audience, although Bailey (2005) outlined the need for a long-term research program on CVF. This work focuses on the role of deep CO2 at CVF, which is considered an intrinsic component of carbonatitic mantle magmatism (Hamilton et al., 1979). Previous, studies of CVF volcanoes considered that the hydrovolcanism is a necessary and sufficient condition to explain the CVF volcanological features, and, as a corollary that the carbonate present in the pyroclastic rocks is remobilised limestones (e.g., López-Ruiz et al., 2002).
