ALLEMONTITE


Meaning of ALLEMONTITE in English

the mineral arsenic antimonide (AsSb). It commonly occurs in veins, as at Allemont, Isre, Fr.; Valtellina, Italy; and the Comstock Lode, Nevada. It also is present in a lithium pegmatite at Varutrsk, Swed. Polished sections of most specimens of allemontite show an intergrowth of allemontite with either pure arsenic in a vein occurrence or with nearly pure antimony in a pegmatite occurrence. Homogenous allemontite has also been found at Varutrsk. For detailed physical properties, see native element (table).
