By modifying magnetic susceptibility values, a reasonable overlap of calculated and observed magnetic fields was achieved for physical properties that resemble those of the Taadikvere quartz monzonite, Abja quartz monzodiorite and Sigula gabbro-diabase intrusions (models 6, 8 and 9 in Table 1 and Fig.
Saw sampling over the area outlined quartz monzonite rocks with pyrite and oxidized pyrite being the dominant sulphide mineral along with minor Chalcopyrite, Chalcosine, Molybdenite and Malachite (Oxide).
Geological mapping and detailed petrography suggest that the Dinsi area is principally occupied by medium-grained porphyritic granite and quartz monzonite which covers the western part of the outcrop area.
These correspond with areas of historic mine workings, pits and trenches over several areas of copper-oxide mineralization and alteration within Jurassic quartz monzonite, the main host for mineralization at both Ann Mason and Blue Hill.
The formal names of these plutons in the New Brunswick bedrock lexicon are the Landry Brook Quartz Monzonite and Dickie Brook Quartz Monzonite; however, to avoid exclusivity in the various rock types forming them, they are referred herein simply as plutons.
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.
Formed by molten liquid that oozed upward from the inner earth, the liquid cooled before reaching the surface, forming an igneous rock called quartz monzonite, similar to granite.
All of these units were intruded by the Lened quartz monzonite stock that has been dated at 93 [+ or -] 1 Ma, using K-Ar on biotite (Gordey and Anderson, 1993).
on a Saturday I find myself standing in a parking lot in Southern California's Joshua Tree National Park, which is famous for the quartz monzonite rock that draws climbers from all over the world.
Mineralisation at Cadia is hosted in units of the Forest Reefs Volcanics and the Cadia Hill Monzonite, and is spatially related to the porphyritic quartz monzonite (porphyry) phase of the intrusive stock.
