Trachite
Trachite is a fiery effluent rock that contains many alkali field sprays. Of which mainly potassium feldspar. The mostly gray colored trachyte contains pyroxene and amphibole minerals, however there may be small amounts of quartz and nepheline in the rock. The silica concentration is high, the silica is not in the quartz as usual, but in the feldspars. The name is derived from the Greek word for rough, because the rock feels very rough.
