4.1. Stops (see page 20 - Fig.10):
Stop 1.
The deposit panorama survey from the highest point of the open pit
southern bort. The dykes exposed in the northern bort of the open
pit, part of the Ermakovka stock and partially developed ore zone I
(stop is outside Fig.11) are well observed.
Stop 2.
Endocontact
quenching zone of stock with structures of dendrite quartz and
aegerine crystal transversal growth.
Stop 3.
Garnet-vesuvianite scarns with relics of Pre-Mesozoic granites.
Low-grade ores of south-eastern ore zone I pinching out.
Stop 4.
Typical
dykes of porphyry-like quartz monzonites and quartz syenites.
Stop 5.
North-western
termination of ore zone I, fluorite-bertrandite-fenacite ores of the
highest quality.
Stop 6.
The crosscutting relationships between granites of the Ermakovka
stock and porphyry-like quartz syenites being similar to dykes that
were observed in Point 4; schlieren pegmatites that contain large
crystals of light-green fluorite with primary inclusions of late
magmatic fluid.
Stop 7.
Felsite
dyke in granites of the Ermakovka stock.
Stop 8.
Ore
zone XVII of fluorite-eudidymite composition.
Stop 9.
Piles
of various composition massive ore large blocks.
