28. Depósito de Au, Pd e Pt associado a granito, Mina Buraco do Ouro, Cavalcanti, Goiás : caracterização e modelo da mineralização. A região nordeste de Goiás apresenta diversas ocorrências, garimpos e minas de ouro, documentadas desde a primeira metade do século XVIII, ainda no período colonial.
This work is a first approach on the REE occurrence of the Ouro Fino Intrusive Suite, a peralkaline granite with A-type affinity located at the Brazilian-Bolivian border. An integration of geochemical data from soil samples from previous surveys of the Geological Survey of Brazil with airborne geophysical data resulted in a prospectivity model.

At Sams Creek a gold-bearing, peralkaline granite pophyry dyke intrudes Ordovician-Silurian metapelite and quartzite. The granite porphyry dyke has a thickness of up to 40 m, extends discontinuously for about 8 km, and intrudes thin lamprophyre dykes along its contacts. The granite dyke and gold-bearing sulphide and quartz-siderite veins within it have been deformed …
A mineralização de ouro no depósito Serrinha é disseminada e restringe-se às áreas de mais intensa alteração hidrotermal do granito Matupá. Os teores de ouro aumentam com a piritização. Magnetita hidrotermal e rutilo acompanham normalmente a pirita. O minério possui baixos teores de Ag Cu Pt Pd Te Se Mo Bi e Sn.

The Jurassic Bokan Mountain complex (BMC), composed of arfvedsonite and/or aegirine-bearing peralkaline A-type granitic rocks, is a circular body about 3 km in diameter located in southeastern Alaska. Like many other highly fractionated granitic bodies, the BMC granites were affected by late magmatic or post-magmatic processes, ...
Genetically related to the Jurassic, Bokan Mountain peralkaline granite Alteration of deposit: This prospect and the other uranium, thorium, and REE deposits associated with the Bokan Mountain peralkaline granite are marked by albitization, chloritization, and argillization
This work is a first approach on the REE occurrence of the Ouro Fino Intrusive Suite, a peralkaline granite with A-type affinity located at the Brazilian-Bolivian border.
The granitic rocks from the Panzhihua, Baima and Taihe plutons are temporally, spatially and chemically associated witfi layered mafic-ultramafic intrusions. Electron microprobe analyses of the major and accessory minerals along with major and trace element data were used to document the magmatic conditions of the tfiree peralkaline plutons.

The Archean high-K magmatism is represented by different types of granitoids (e.g. sanukitoids, biotite granites, peralkaline granites, syenites, etc.; see Moyen et al., 2003 and Laurent et al., 2014a for details) of mainly crustal origin, although mantle sources and interaction between crustal and mantle end-members have also been suggested as petrognetic …
type), trondhjemitic (Serrita type), peralkaline (Catingueira type) and shoshonitic (Serra dos Cavalos type) suites (Ferreira et al. 2004, Medeiros 2004). In the studied area, plutonic stocks correlated to Serrita Trondhjemitic Suite are intrusive in schists and phylli-tes correlated to the Salgueiro Group (Sial et al. 1981, Neves 1986) (Fig. 2).
A synthesis of available data on REE concentrations in peralkaline granites of India is presented. Although peralkaline granite-hosted REE deposits are known world over, and one such deposit has also been mined actively in Kola Peninsula of Russia, but in India such deposits have not yet been established. Initial results of investigations reveal that peralkaline fine-grained granite …

The solubility of H,O in a series of 13 melts based on a haplogranitic composition (HPG8) have been determined for the conditions of 500-5000 bar pressure and 800-1000 'C. The compositions represent the additions of individual components (CsrO, RbrO, KrO, Na,O, Li,O, and Al,O.) to HPGS (in wt%o 78.6 SiO,, 12.5 A1,O.,4.6 Na"O, 4.2 K,O; see Knoche et al. 1995) to generate …
The peralkaline composition of the Sams Creek granite and the absence of molybdenite and paucity of chalcopyrite, are major points of difference with gold-rich porphyry copper deposits. The presence of a lowsulf idation-state ore mineral assemblage, carbonate alteration and carbonic fluid inclusions at Sams Creek are typical of many of the reduced granitic intrusion-related type …
The peralkaline Papanduva granites show both minimum and maximum values, and a higher mean (3.6 µWm –3) when compared to the Quiriri granites, with a narrow range of variation (2.6 – 3.5 µWm –3) and a mean of ∼3.0 µWm –3. The felsic microgranular enclave hosted by the main Quiriri granite gives 3.6 µWm –3.
