Abstract:

Metasedimentary rocks of Delhi Supergroup (900-1600 Ma; latitude 28°2΄ - 28°7N΄ and longitude 76°3΄ - 76°7΄ E) are exposed in the Aravalli Mountain (South of Haryana State). The metasedimentary rocks are mainly quartzite with lesser amount of schist, granitic gneiss, basic rocks, calc rocks, phyllite, slate, granite, pegmatite and veins of quartz. Most of the pegmatites of the study area intruded into the quartzite. Pegmatites occur as irregular masses, dyke swarms, branching dykes, criss-cross veins and elongated lenses. They strike in NNE direction with low dip angle. Their dimensions are va

Abstract:

ABSTRACT:Until the last few years, diapirism reigned supreme among granitoid ascent mechanisms. Granitoid masses in a variety of material states, from pure melt through semi-molten crystal mushes to solid rock, were believed to have risen forcefully through the continental crust to their final emplacement levels in a way analogous to salt domes. The structural analogy between granite plutons and salt diapirs, which gained acceptance in the 1930s, has clearly been attractive despite the pessimistic outcomes of thermal models and, at best, ambiguous field evidence.In contrast with traditional di

Abstract:

Detailed structural maps of two granitoid complexes in the Wabigoon Subprovince are used to test three diapir hypotheses advanced in earlier papers. The gneiss masses of, and individual domes within, the complexes fail the test for solid-state diapirism. The gneiss domes also fail the test for tensile bending caused by hypothetical magmatic diapirs in the subsurface. An oval pluton located near the best-exposed gneiss dome proves to be a synformal sheet rather than a funnel-shaped magmatic diapir. This pluton could be a syenite–diorite phacolith emplaced into a concordant zone of dilation duri

The mechanical strength is a fundamental characteristic of rock masses that can be empirically related to a number of properties and to the likelihood of instability phenomena. Direct field acquisition of mechanical information on tall cliffs, however, is challenging, particularly in coastal and alpine environments.

Using a drone-mounted thermal camera and a Schmidt (rebound) hammer, we surveyed granitoid and aphanitic blocks in a coas

The latter occur as small cordieritic intrusions associated with 1-type granodiorites and as abundant cordierite-bearing facies in large batholithic masses.

ABSTRACT. Geophysical surveys were accomplished in Bahia, Brazil, and they aimed at detecting resistivity and/or IP geophysical anomalies that may be correlated to large quartz mass occurrences that, in some cases, may have economic interest (hyaline high-quality quartz or quartz with rutile inclusions). These quartz masses occur in granitic rocks. The indirect geophysical detection of quartz masses was possible, however it could not differentiate the aforementioned types of quartz. After digging wells and trenches, the presence of milky quartz masses, without economic interest, was confirmed.

Abstract:

Many years ago, V.S. Sobolev suggested that the reason for the relative prevalence of intrusive and effusive rock masses in the earth’s crust lies in the regularities of viscosity of water-bearing magmas in a variable field of temperatures and pressures. Alas, in those years it was not possible to solve this problem on a quantitative physical-chemical basis, since experimental and theoretical studies of the viscosity of such melts at high pressures were just beginning. In the present work, new regularities of the viscosity of near-liquid water-bearing acidic magmas in a wide range of thermodyn

We report here for the first time the occurrence of chloritoid in Mg-Al-rich metapelitic rocks of the Silgará Formation at the Central Santander Massif, which was metamorphosed up to the amphibolite facies. These rocks contain an unusual mineral assemblage such as quartz + biotite + muscovite + garnet + staurolite ± kyanite ± chloritoid, with minor plagioclase and K-feldspar, and Fe-Ti oxides as the main accessory phases. Associated carbonate rocks containing the mineral assemblage tremolite + calcite. Chloritoid occurs as porphyroblastic tablets in graphite-bearing metapelitic schists highly

Expansão por umidade (EPU) é o aumento das dimensões dos materiais cerâmicos em virtude da adsorção de água. A EPU geralmente ocorre lentamente e é relativamente pequena, mas, mesmo assim, pode comprometer a aderência das placas cerâmicas ao contrapiso, levar ao gretamento do vidrado e conduzir ao aparecimento de trincas em tijolos. Neste trabalho empregaram-se massas incorporadas com resíduos de caulim e de granito objetivando estudar a EPU de revestimentos cerâmicos. As matérias-primas foram beneficiadas e submetidas às caracterizações físicas e mineralógicas através de ensaios de análise gr

Canada, along with other countries that are considering the permanent disposal of high-level radioactive wastes from nuclear power generation, is undertaking a program of research into deep geological disposal. This program, led by Atomic Energy of Canada Limited (AECL) with support from Energy, Mines and Resources Canada, other federal government departments, universities, and industrial consultants, has been in progress since early in 1973. Geoscience research, the subject of this symposium, complements research on fuel waste immobilization to provide the data and information essential to th

The Abu Farayed Granite (AFG), located in the southeastern desert of Egypt, was intruded during the early to late stages of Pan-African orogeny that prevailed within the Arabian–Nubian Shield. The AFG intrudes an association of gneisses, island arc volcano–sedimentary rocks, and serpentinite masses. Field observations, supported by remote sensing and geochemical data, reveal a composite granitic intrusion that is differentiated into two magmatic phases. The early granitic phase comprises weakly deformed subduction-related calc–alkaline rocks ranging from diorite to tonalite, while the later en

  The Greater Caucasus belt is the northernmost expression of the Caucasus orogen and is linked to the southern margin of the Precambrian Scythian Platform. In the pre-Jurassic crystalline basement of this belt, a plagiogranite vein, exposed in the headwaters of the Enguri River, with elevated radiation (μSv/h range of ~1–3), has been discovered. The vein is located along the Main Thrust of the Greater Caucasus, in the upper Paleozoic biotite migmatites of the Shkhara crystalline massif. It is ~2–3 m thick and represents hydrothermally altered rock

Thin (tens of metres wide by tens of kilometres long) sheets of metagabbroic anorthosite are a common and intriguing feature of the Central Gneiss Belt (CGB), southwestern Grenville Province. Their origin, however, as either tectonic remnants of originally much larger parent masses or as moderately strained magmatic sheets is controversial because regional high strain has largely obliterated original contact relationships and modified primary textures. The origin of three sheets of metagabbroic anorthosite within the Fishog subdomain of the CGB is examined. Field relationships and geochemical
