2008), this region is occupied by the large Kursiai batholith with a few minor plutons made up of a suite of dominantly charnockitic granitoid
rocks (mangerite, enderbite, opdalite, charnockite and granite).
Paleoweathered surfaces on granitoids
of southern Nova Scotia; paleoenvironmental implications of saprolites.
Abnormal potassium peak is probably due to potassic alterations in the region's granitoid
It should be noted that with decreasing the content of refractory clay and simultaneously increasing the quantity of granitoid
screenings and dolomite, the rise of the diffraction peaks of anorthite is noted, the formation of which is explained by the reaction between CaO, arising during the decomposition of dolomite, with metakaolinite formed during firing of clay and quartz, the introduced with quartz sand.
As was mentioned above, in the study area the main sources of high Rn concentrations in soil air are the Lower-Ordovician U-rich rocks, graptolite argillite, and obolus sandstone (phosphorite), and among the Quaternary deposits, clasts and fines of the above-mentioned rocks and to a lesser extent the Quaternary deposits enriched with erratic granitoid
material of the rapakivi formation.
pebbles, cobbles and boulders are characteristic of some of the ore-bearing breccias.
These growth periods have been previously interpreted as occurring during forceful intrusion of the Hyde School composite granitoid
This study draws on mapping within the Blue Ridge of Alabama, a terrane composed of Neoproterozoic metaclastic and metavolcanic rocks intruded by Paleozoic granitoid
They gave a party for us at the home of a prominent businessman, and after things had started rolling, a handsome woman came up the granitoid
walk and entered the house.
The drill holes intersected an east-west striking, steeply dipping mineralized zone hosted in felsic volcanic (ignimbrites) and granitoid
Sm-Nd isotopic studies on Meguma granitoid
rocks (Clarke et al.
In order to identify the granitoid
mass in Ghareh Gheshlagh, thin layers of the samples were taken besides field studies that helped in identifying these minerals.
Kwabena Mensah, Principal Geologist, believes that the initial focus of the drill program will be within the central portions of the permit where there is evidence of structurally controlled metasedimentary rocks within granitoid
Figure 4a shows how erosional remnants of a sedimentary cover consisting of Ordovician limestone can be differentiated from the underlying Archean granitoid
basement by its relatively bright tone on a LANDSAT TM colour composite image of southwestern Baffin Island, Nunavut.
Migmatization is widespread, resulting in the formation of plagioclase and potassium-feldspar porphyroblasts and occasionally charnockitic leucosomes, also of small granitoid
veins and bodies.
