Bromine-methanol dissolution, which is mainly used in analysis of metallurgical specimens, has been applied to geological samples. It has been established that a solution of bromine-methanol dissolves sulphides and arsenides very selectively but attacks silicates and oxides only slightly. An exception is pyrite, of which merely 7 to 8 °/o is dissolved under the conditions defined in the analytical instructions.
