REE in New Mexico: peralkaline igneous rocks, granite, and pegmatites (Fig. 1). Many peralkaline igneous rocks, typically of syenite or granite composition, have higher concentrations of REE and Zr then other types of igneous rocks. Alkaline rocks are defined as rocks with Na 2O+K 2O>(SiO 2) (MacDonald and Katsura, 1964) or rocks ...
Khan Bogd Peralkaline Granite, Khanbogd District, Ömnögovi Province, Mongolia : The largest known intrusion of peralkaline granites. Extends over 1500km². It is emplaced into Paleozoic sedimentary and volcanic rocks and consists of 2 roughly circular overlapping intrusions, of ...
Jan 19, 2006· At Sams Creek, a goldbearing, peralkaline granite porphyry dyke, which has a 7 km strike length and is up to 60 m in thickness, intrudes camptonite lamprophyre dykes and lower greenschist facies metapelites and quartzites of the Late Ordovician Wangapeka formation. The lamprophyre dykes occur as thin (< 3 m) slivers along the contacts of the granite dyke. δ18Omagma .

Deposits that form part of the graniterelated mineral system include graniterelated SnWF (including a variety of skarn deposits), pegmatitehosted TaNbLiBe, porphyry Mo and intrusionrelated gold deposits. Aspects of the graniterelated mineral system are presented by ?erný et al. (2005), Ludington and Plumlee (2009) and Hart (2005).
The albite granite is composed by two facies. The dominant is a gray, peralkaline core facies (CAbG), which is composed essentially by albite, quartz and Kfeldspar, accompanied by cryolite, zircon, polylithionite, riebeckite, LiFe mica, cassiterite, pyrochlore and magnetite. .

The Keivy peralkaline granite complex consists of Ma peralkaline granites, 2670 Ma syenogranites, and 2680 Ma alkaline syenites. The granites form sheetlike bodies with thicknesses of a few hundred meters, but have vast exposed areas ( km 2). They are metamorphosed to amphibolite facies and are bounded by gabbroanorthosite.
The results show that the peralkaline Atype granites and syenites were episodically emplaced in SuizhouZaoyang region between 450±3 and 441±7 Ma which corresponds to Late Ordovician and Early ...
In the JTP, gold occurs mainly in highgrade small deposits hosted in quartz veins and often related to shear zones, or disseminated in widespread hydrothermal zones. In the Matupá Granite, gold seems to be related to a porphyry system (Botelho and Moura 1998). The mineralization is concentrated in the most intensely hydrothermalized zones.
Hydrothermal Ore Deposits, Rare Metals, Fluid Inclusions, Peralkaline Rocks, Geochemistry. My research is devoted mainly to understanding the formation of hydrothermal ore deposits. In particular, I have investigated raremetal bearing alkaline rocks, orogenic gold deposits, pegmatites, porphyry deposits, and gems.
At Sams Creek a peralkaline granite porphyry dyke hosts goldbearing sulfidequartzsiderite veins. The granite dyke intrudes OrdovicianSilurian metapelite and quartzite, and has thin lamprophyre dykes along its contacts. The mineralised veins and the granite and lamprophyre dykes have been deformed during several phases of folding, the youngest of which is Early Cretaceous.
At Sams Creek a goldbearing, peralkaline granite pophyry dike intrudes OrdovicianSilurian metapelite and quartzite. These metasedimentary rocks have undergone three phases of folding: a first phase of recumbent folds (F1), a second phase (F2) of northerlytrending inclined folds with a prominent crenulation cleavage, and a third phase (F3) of steeply plunging folds.

Gold was discovered in Sams Creek, 25 km south of Takaka in 1974. Exploration surveys have defined an inferred resource of 776,000 ounces of gold. Gold is associated with an arsenopyritepyritequartzsiderite vein stockwork in a peralkaline granite porphyry dyke, which intrudes 500 .

The Kuiqi arfvedsonite granite near Fuzhou is a lithological representative of peralkaline Atype granite in SE China. Martin et al. (1994) suggested that the Kuiqi peralkaline Atype granite was younger than the coexisting rocks in the area, but our chronological data suggested that it was coeval with the aluminous Atype granites in this area.
Gold mineralization is hosted by a peralkaline granite dyke which outcrops over about eight kilometers in the area of Sams Creek, a tributary of the Takaka River, northwest Nelson. The granite is riebeckite and acmite bearing, with antiperthitic alkali feldspars; it has Atype chemistry, implying an origin by partial melting at a temperature ...

Unlike the REErich Strange Lake peralkaline granite, neither the Longs PeakSt. Vrain granite, aplite dikes, nor the F, P 2 O 5 and REErich segregations has undergone subsequent hydrothermal alteration. Samples from this locality, therefore, provide a unique opportunity to evaluate the distribution of elements between immiscible silica–flu
Syenite is a coarsegrained intrusive igneous rock with a general composition similar to that of granite, but deficient in quartz, which, if present at all, occurs in relatively small concentrations (< 5%).Some syenites contain larger proportions of mafic components and smaller amounts of felsic material than most granites; those are classed as being of intermediate composition.
Taking the Stange Lake granite from northeastern Canada as an example, this granite is a small, extensively altered, peralkaline stock that hosts one of the largest Zr–Y–REE–Nb–Be deposit in the world (Salvi and WilliamsJones, 1995, Salvi and WilliamsJones, 1996).
