Interesting minerals of charoite rocks. Benston-Benstonite
The mineral is found in charoite rocks in the form of a rare accessory admixture, but it is a rock-forming material for the adjacent benstonite carbonatites, which are a promising source of barium and strontium. The mineral benstonite, with the chemical composition Ba6Ca6Mg (CO3) 13, was first discovered by Orlando Joel Benston (1901-1966), after whom it was later named. The newly discovered mineral was investigated by the German geologist Friedrich Lippmann (1928-1998) from the University of Göttingen (Federal Republic of Germany). Samples in which the mineral was discovered were taken at a barite mine, Magnet Cove near Malvern, Arkansas, USA. Orlando J. Banston during this time worked in the beneficiation division of the National Lead Co. metallurgical company in Malvern.
Another mineral found in charoitites and imprinted on the name of the mineralogist-researcher is miserite.
Among the minerals of charoitite rocks, there are the names of not only modern geologists, but also researchers of other specialties, whose peak of activity occurred in the middle of the 19th century.
Among the accessory minerals of charoite rocks, there is such a mineral as dalyite, named in 1952 in honor of the American petrologist Reginald Aldworth Daly (1871-1957).
В 1995 году в честь известного учёного, Виктора Альбертовича Франк-Каменецкого (1915-1994), был назван новый минерал, найденный в чароитах, - франкаменит.
This mineral is also remarkable for its name, which refers us to one of the outstanding naturalists of the late 18th - early 19th centuries - William Hyde Wollaston (1766-1828).
