This rhyolite was collected from the Zuun tsagaandel area located in the Ikh khet soum, Dornogobi province, Mongolia and prepared as a candidate reference material by the Central Geological Laboratory, Ulaanbaatar, Mongolia. The material consists of a homogeneous powder, all of which passed through a 75 μm sieve.
The mineralogy of the sample (in g/100g) has been determined as 38 potassium feldspar, 30 quartz, 25 plagioclase, 6 biotite, few grains of ilmenite and magnetite, and traces of sphene and apatite.
The material is available in units of 100 g packaged in a polyethylene bottle.
