OF THE HYDROTHERMAL TYPES ALTERATION FROM NISTRU ORE DEPOSIT, BAIA MARE METALLOGENETIC DISTRICT FLOAREA DAMIAN1 ABSTRACT. The hydrothermal alteration types, which have affected intrusive and volcanic rocks from Nistru ore deposit, are related to fluids composition varied in their evolution within hydrothermal systems.
About Gold Hide. Gold occurs in significant amounts in three main types of deposits: hydrothermal quartz veins and related deposits in metamorphic and igneous rocks; in volcanicexhalative sulphide deposits; and in consolidated to unconsolidated placer deposits. It may also occur in contact metamorphic or hypothermal deposits (eg.
The ore of gold possesses only very small quantities of gold, the ore is normally brown, a rock stained with iron, or a huge white quartz. Gold is extracted from gold mines by merely crushing the ore and further separating the gold by some means.

Oct 17, 2016· These type of sulfide ores are probably the best known and most commonly encountered by smallscale miners and prospectors. The gold's host rock typically contains quartz (although again, many iron sulfide ores are not quartzitic).
After the ore has been mined, the rock will turn grey for a while. Eventually another ore will respawn and the rock will regain its colour. Players can only mine a rock when ore is available. Ore respawn times differ with the difficulty of the rock. For example, runite rocks take 12 minutes to respawn while iron rocks take about 3 seconds.
