The Eastern Highlands Shear Zone has been recognized to display a protracted period of motion (Lin 1995), although the dominant phase of mylonite
development ended in the Late Devonian.
SAMPLE DESCRIPTION The selected sample (TV-336) is an augen granitoid mylonite
from the Tverecius-336 drill core, located in the eastern part of the DPDZ close to the Belarus border (Fig.
zoned, helicitic, calcium-rich almandine garnets from the Hyde School Marginal Mylonite
of the Adirondack Lowlands and to date (U-Pb) monazite inclusions in the cores and rims to verify the hypothesis that there were two episodes of garnet growth, currently based upon textural observations, chemical zoning, and geothermometry.
The above geological and analytical results continue to be consistent with those previously encountered for the B-14 Zone with the zone persisting as a moderately dipping shear zone marked by increased sericite and carbonate alteration, quartz veining, and pyrite hosted by mylonite
In the Hosenbein pluton, modal layering is most abundant in the Marginal Zone, where it shows mostly gneissic texture that locally grades into mylonite
It is possible that these high grade shoots are oriented such that the drill density to-date, designed to define the mylonite
zone, is insufficient in delineating the smaller, but much higher grade shoots.
The SZD has been traced over a 1 km strike length and remains open under the glacial-fluvial deposits of the Todd Creek Valley towards the Knob Zone, 4 km to the north; and, towards the Mylonite
Zone, 3 km to the south.
The Company continues to find that the B-14 Zone persists as a moderately dipping shear zone marked by increased sericite and carbonate alteration, quartz veining, and pyrite hosted by mylonite
We've got one high grade, quartz-rich shoot within a very broad lower grade mylonite
Also anomalous on Isle Madame are three long narrow belts of "basement" rocks, together with voluminous chloritic microbreccia and minor semi-ductile mylonite
, which are separated from the conglomerate-dominated successions by faults.
Old pits and trenches were mapped along a 300 m length and a series of vein grab samples were taken that often contained chalcopyrite (copper), galena(lead) within a reddish-brown mylonite
(shear) and gave the following distribution of values.
Project site geology is characterized by a gentle dipping, Miocene-age detachment fault juxtaposing upper plate Tertiary andesite with lower plate, Precambrian, granitic mylonite
