Dalnegorsk is one of the most important mineralogical districts in the Russian Far East, well known for the high quality and diversity of its mineral species.
Geologically, the area is characterized by skarn-type mineralization and hydrothermal deposits associated with Mesozoic igneous intrusions. These systems have produced a wide variety of minerals, including lead, zinc and boron species, with abundant secondary minerals formed in oxidation zones. Dalnegorsk is especially famous for its Fluorite, Galena, Calcite and a wide diversity of borate minerals.
