Estimated delivery between 06 December and 11 December.
The deposit known as Dalnegorsk is mined by several different mines. The vast majority of the minerals from Dalnegorsk in various collections have no reference to the individual mines. The mines are the Brenner mine (with the Svetlana adit and Olga adit), Nikolaevsky mine, Zentralnye mine, Verkhnii mine, East Partizan, 1st Sovietsky mine and 2nd Sovietsky Mine. There are probably more mines. The name "Tjetjuche" means "valley of the wild pigs" and is the old Chinese name for Dalnegorsk and this name can be seen on old mineral labels.
Geologically Dalnegorsk is best described as a skarn, although it is not a pure skarn. Magma came into contact with limestone forming a skarn. But the difference is that metamorphic volcano-sediments are also present and ore bearing. The limestone has an age of carboniferous to jurassic and is covered with upper cretaceous to lower tertiary volcano-sedimentary rocks..
Most ores occur at the contact and in the limestone. The orogenese can be divided into four phases. Non-ore bearing skarn phase with mainly garnet and wollastonite, the skarn sulphide phase, a polymetallic phase and lower temperature final phase with mainly quartz, calcite and zeolites. In the skarn sulphide phase many boron minerals are formed as well as sulphides. Similar sulphides are formed in the 3rd phase.
