in Mineralogy, a green-coloured variety of hornblende, which generally occurs massive, or in con- cretions so loosely aggregated as to admit of being sepa- rated by the fingers. It fuses with difficulty before the blowpipe, and has a specific gravity of 3-3. It occurs with garnet and granular limestone in the iron mines of Arendal in Norway, at Pargas in Finland, and elsewhere.
