Signs of potential mineralization of rocks of alkaline basaltoids 
and lamprofir formation 
Typomorphic characteristics of gold-tungsten 
mining of the lower tier of the Yachton deposit 
Geochemical specialization 
Rock formations of alkaline basaltoids and lamprophyres at the 
boundary of the yacht area are characterized by the presence of 
a number of elements (Au, Ag, W, Mo, Se, Te, Bi, As, Sb, Re, Hf) 
that have higher amounts than clark in virtually all types of 
dyke products. 
The geochemical sequence (Te-Se-Au-Bi-As-Ag-Sb-Re-Hf-W-
Mo) of the rate of accumulation of basic elements in ore-
generating magmatic products of the formation of alkaline 
basaltoids and lamprophyres indicates that they have 
geochemical specialization predominant in gold and rare metal 
mining sufficiently clear. 
The typomorph Au, W, Bi, Te, As, Ag, Se, Mo, Su, 
Sb is a geochemical association for gold-tungsten 
ore of the lower tier of the Yachton deposit. 
The main minerals of the sulfide part of the ore are 
pyrite and pyrrhotite. 
Amount of mixed elements (g/t): in pyrite – Au - 
22,9; Ag - 51; , As - >4000; Te - 47; Se - 42; and Bi 
- 1600; pyrrhotite – Au - 3,5; Ag - 3,5; As - 85; Te - 
7,3; Se - 17; and Bi - 400. 
Mineral- accessor specialization 
Basic 
paragenetic 
mineral 
association 
of 
mineralization 
The potential mineralization of gold is confirmed by the 
accumulation of natural gold grains and sawdust found in 
different rocks of the formation in untouched, unchanged 
species by metasomatic alteration processes. 
In addition, xenolites with natural gold carbonated peridotites 
were detected, as well as pyroxene-porphyry trachybasalts 
containing brecciated and ultrabasic xenolites. Natural gold is 
associated with sheelite, molybdenite, cinnabar, magnetite, 
galena, sphalerite, pyrite, fluorite, chalcopyrite and graphite. 
The specialization of alkaline basaltoids - rocks of the formation 
of lamprophyres in tungsten is confirmed by the presence in 
them, as well as in carbonated pyridotites (xenoliths), the 
accelerator sheelite. 
For tungsten - albite-sheelite. 
For gold - tetradimite-tellurovismutite, gold - 
silver, gold-hessite and pyrite-arsenopyrite. 
Mineral forms of gold are natural tellurides in 
association with natural gold and natural silver, 
pyrite, pyrrhotite, ores, arsenopyrite. 
Features of metasomatosis 
In xenoliths, hyperbasites are characterized by highly 
carbonated listvenites and are described as a metasomatic type 
resulting from the treatment of magmatic solution in the 
deeper parts of the igneous chamber with high-potassium 
mantle fluids of carbon dioxide. In addition to the high 
concentration of potassium, the fluid was significantly 
saturated with gas and water. 
Integrated siliceous metasomatosis, which brings 
Ca, Si, Mg, Fe to the periphery. 
For 
metasomatites 
formed 
along 
the 
aluminosilicate substrate, which has several 
modifications, the constant presence of calcite in 
practice is characteristic. 
The presence of thin veins of brownish-black 
symbolic substance (anthraxolite type), which 
records the arrival of juvenile carbon in 
metasomatites.
