Locality type:
Group of Mines
Köppen climate type:


Tungsten deposits in a horizon of migmatitic high-grade metapelites in the so-called Wolfram formation (or Wolfram mine schist formation) below a granite sheet. The schist horizon can be traced over a length of several kilometers, giving the mineralization the appearance of a stratabound deposit.

Geochronology

Mineralization age: Stenian : 1015 Ma to 1007 Ma

Important note: This table is based only on rock and mineral ages recorded below and is not necessarily a complete representation of the geochronology, but does give an indication of possible mineralization events relevant to this locality. As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.
