... but intense 18 O enrichment (8.5-14ppm). The combined pattern of concentric light and heavy alteration has a diameter of approximately 30 km. The Clericy intrusion shows a similar pattern of isotope alteration on a smaller (10 km diam) scale. The Lake Dufault pluton seems to have been isotopically altered...

..., volcanism occurred sporadically throughout much of the area, culminating in the eruption of the Blake River Group from 2703 to 2698 Ma. Several large intrusive bodies yield ages that indicate that they are plutonic equivalents of the Blake River Group. Plutons that are considered to have been emplaced...

... (Iyengar and Bane~jee, 1964; Iyengar and Alwar, 1965; Iyengar, 1978) varies from coarse to aplitic and gronophyric types with chilled margins at the floor and at the roof of the intrusions. The coarse granite types are, as a rule, found at the bottom of the intrusion passing upwards into riebeckite granite...

... of 9 m.y. Nineteen new high-precision U-Pb ages temporally constrain the host rocks of many poly-metallic VMS deposits and associated synvolcanic intrusions, demonstrating that these VMS deposits formed throughout the protracted volcanic evolution of the entire group. Ages on host rocks of the Horne...

.... The Khibiny massif is the world’s largest intrusion of nepheline syenite and foidolite. Igneous rocks, pegmatites, and hydrothermalites of the massif consist of more than 510 species including 104 minerals found there for the first time. Recently discovered microporous titanosilicates of Na, K, and Ca attract...

...}. Density could not be measured; the mineral sinks in the heaviest liquid available, diluted Clerici solution ( D ≈3.8 g/cm 3 ). The density calculated from the empirical formula is 4.21 g/cm 3 . Crystals are readily soluble in cold dilute HCl. The mineral is optically non-pleochroic and uniaxial...

... magnetites from 16 samples of magnetite-quartzites and 8 samples of pyroxene granulites were obtained by crushing the samples to fine powder and separating the magnetic fraction by hand magnet. Further purification and separation were carried out by wet methods using Clerici solution, bromoform, and acetone...

... is based on the assumption that future landslides occur under similar conditions as those observed in the past ( Saha et al. 2005 : Wang and Sassa, 2005 : Clerici et al. 2006 ; Chen and Wang, 2007 ; Pandey et al. 2008 ). Landslide prediction models, in general, classify the area into different...

.... Binary data plots of unit cell dimension (a 0 ) versus oxidation grade/composition (UO 2+x ) of uraninites (n = 36) suggest that the gross uranium mineralisation in the albitite belt of western India is mainly linked to regional metamorphism, anatexis, granitic intrusion, metasomatism, and contact...

... (Russia) is the largest alkaline intrusion in the world, occupying an area of 1327 km 2 at the current erosion level. It was emplaced at the contact between the Imandra-Varzuga Proterozoic greenstone belt and Archaean metamorphic complexes of the Kola-Norwegian megablock. About 70% of its area...

Most of the massif rocks are covered by moraine or glaciers and/or are difficult to access. In the north, the massif intrudes Silurian limestones and slates; in the south...

... to accurately measure the density of the mineral in nearly saturated Clerici solution were unsuccessful because of difficulty in making observations in the murky, reddish, somewhat viscous solution; however, it was obvious that the density of the mineral was close to that of the solution (4.1–4.3 g/cm 3...
