The Buk-M3 system boasts a new digital computer, high-speed data exchange system and a telethermal
imaging target designator instead of the teleoptical trackers used in previous models.
It was previously considered to be a Mississippi Valley-type of low-temperature, telethermal
galena-sphalerite-pyrite deposit which has been thoroughly oxidized (Alvarez and Giles, 1986; Ransome, 1927; Ransome and Patterson, 1928).
Presence of breakthrough breccia in Chattanooga similar in setting to telethermal
Mississippi Valley Type deposits elsewhere in the Knox Group is indicative of involvement of fluids of higher temperatures.
Occurrence: In a telethermal
selenide vein-type assemblage.
