Type Occurrence of LeningraditeHide

Type Locality:

ⓘ Second scoria cone, Northern Breakthrough (North Breach), Great Fissure eruption (Main Fracture), Tolbachik Volcanic field, Milkovsky District, Kamchatka Krai, Russia

General Appearance of Type Material:

Single poorly faceted red-brown rhomboidal crystals or flakes, or as intergrowths of fine tabular crystals. The crystals/flakes measured up to 0.3 mm across (ordinarily 0.1 mm) and about 0.3 mm thick. The intergrowth aggregates had the appearance of microscopic spheres or globules up to 0.6 mm in diameter (usually 0.2-0.3 mm), with rough maroon-brown surfaces. Internally, some of the spherical particles resembled spherulites, with the crystals oriented in an orderly fashion from the center to the edges; in other cases the crystals were in a spiral arrangement.

Place of Conservation of Type Material:

Mining Institute, St. Petersburg, Russia, 2003/1.

Geological Setting of Type Material:

Fumarole.
