Several alteration styles have been observed on the Property, including intense silicification associated with massive chalcopyrite mineralization, sericite, and hematite veining within a monzonite
The Taadikvere quartz monzonite
intrusion contains anomalously large amounts of ore and the accessory minerals hornblende, apatite (1-2%) and titano-magnetite (2-5%) (Niin 1997), which could cause or contribute to the observed potential field signature.
The [Na.sub.2]O + [K.sub.2]O versus Si[O.sub.2] diagram (Middlemost, 1994) shows the plutonic samples ploted in the monzodiorite to quartz monzonite
TREI would use monzonite
sand provided by India's Indian Rare Earths Limited in its production of REEs.
The first 242 m of the hole were hosted in a typical porphyry-copper-style altered monzonite
intrusion and assayed 0.63% copper and 0.85 g/mt gold.
2), which forms most of the northeastern part of the mountain, and a more varied but less extensive dioritic unit that includes quartz diorite, tonalite, diorite, granodiorite, quartz monzonite
, and hornblendite.
The main rock types in the great Sierra Nevada batholit are granitic rocks (granodiorite, quartz monzonite
, tonalite, etc.), which are capped by volcanics and flanked on the western side by older ultramafic rocks (Hill, 2006).
The rock types of the basement, according Adamu (1991), are medium to coarse grained granite, undifferentiated schist, gneisses, granite gneisses, fine grained biotites and biotites-hornblende granite, quartz monzonite
, quartz diorite and granodiorites.
unit, which has been described as a possible diorite and porphyritic microdiorite, monzonite
and granodiorite stock.
Despite its name, Granite Mountain is primarily composed of quartz monzonite
, an igneous rock similar to granite in appearance, physical characteristics, and chemical composition.
Its composition ranges from diorite to monzonite
with gabbros at its border.
Strong alteration was encountered with zones of silicified and tourmaline-altered monzonite
with stockwork quartz veins (up to 0.79 meters wide) and disseminated to massive arsenopyrite, chalcopyrite, pyrite, and rare pyrrhotite intersected in the majority of the holes.
