Main Event of this year
August, 2004. The Fifty Anniversary of the Discovery of first primary deposits of diamond in Siberia made by the young
geologist Larisa Popugaeva.
Mineralogical Club of the Fersman Mineralogical Museum
June 2, 2004. Alexander P. Khomyakov made a very interesting report
“Deposits-giants as products of geocatalysis and minerals –
indicators of their genesis”.
In hot discussion took
participation all Club members, including Boris E. Borutskii,
Igor A. Zotov, Liya N. Kogarko, Svet M. Kravchenko, Ernst M. Spiridonov. The specimens of so-called catalygenic minerals (the
term proposed by A.P. Khomyakov) from author’s and Museum
collections were demonstrated.
Alexander P. Khomyakov presented unique specimen of kogarkoite, largest
segregation (nearly 3 cm in size) of this rare mineral in the
rock (agpaitic pegmatite) from Mt. Alluaiv, to Dr. Margarita I.
Novgorodova, director of the Fersman Mineralogical Museum.
Academician Liya N. Kogarko, in whose honor the mineral was named, told the
interesting story about its discovery. Vasilii I. Gerasimovskii
(1907-1979), famous geochemist, already in 1970’s has paid
attention to wide prevalence of villiaumite (NaF) in the rocks
and pegmatites of Lovozero massif and advised his post-graduate
student Liya Kogarko to search halite (NaCl) in them that would
be interesting finding from the point of view of deposit
genesis. The girl checked all suspected specimens by… the tongue
licking the surface: known salt taste would find out halite. By
this method she once found the mineral with unusual taste. She
considered this mineral as known schairerite, i.e. its
chlorine-free variety. However later in Colorado (Chaffee Co.)
American mineralogists (Pabst & Sharp, 1973) found the mineral
similar to that by chemical composition and properties and
proposed to consider it as a new species, and named it in honor
of L.N. Kogarko, who has found its first specimen.
June 3, 2004, in Malyi Theatre (Moscow) the
presentation of international prize “Philanthropist” took place. Viktor Slyotov
(born 1955), mineralogist and collector, has become one of its laureates for
arts in the nomination “For novelty and originality in art” (pictures of
minerals, verse). First the drawings of the author was shown in 1983 at the
exhibition “Wonderful in stone”, where they have attracted general attraction
with documentary accuracy. In May 2004 the third album of new drawings
of minerals) was published.

New book: Important summary on zeolites
Zeolites of alkaline massifs by Igor V. Pekov,
Anna G. Turchkova, Ekaterina V. Lovskaya, Nikita V. Chukanov. Association
Ekost, 2004, Moscow. – 168 p.
The authors noted that just alkaline massifs,
as it will not seem unexpected, are distinguished by most variety of zeolites
among all geological formations: “59(!) of 91 minerals of considered group
(including 15 endemic species which are found while nowhere except alkaline
complexes) were found here”. In the summary there are the data on this 59 zeolites,
their occurrences, chemical composition (420 chemical analyses), the
IR-spectroscopy, crystal morphology, mineral assemblages, genesis and
typomorphism. The interesting peculiarity of a number of zeolites, enrichment
by rare metals (Sr, Ba, Cs, Rb, Be), was noted. The possible role of sieve and
catalytic properties of zeolites in the hydrothermal processes taking place in
the alkaline massifs is discussed. The book contains numerous REM-photo and
extensive list of references (315 titles).
The results of study of rich collection of specimens from 11 alkaline
massifs of Russia and foreign countries were underlain in the base of this
work. In the supplement there are the brief description of the specimens, the
references on that are given in the text and tables. Many of the specimens were
collected by the authors during field works in Lovozero and Khibiny in the last
15 years. In these massifs zeolites (in particular, natrolite) not only form
vast accumulation but also are diverse (Kirovskii mine and Mts. Alluaiv,
Karnasurt are stood out). I.V. Pekov has also visited alkaline massifs of
Greenland, Morocco, Canada. Many specimens were given to the authors for study
by famous collectors (Laszlo Horvath, Alexander Podlesnyi, Viktor
Grishin, Viktor Levitskii, Aleksei Timofeev et al.), colleagues (Alexander
Nikiforov, Dmitrii Lisitsyn, Mikhail Moiseev et al.), Geological Museum
of Kola Scientific Center. The prevalence of zeolites in alkaline massifs and
their localities are considered in large chapter containing references on
findings of rare species interesting to mineralogists and collectors, for
example, lovdarite and paranatrolite from Point of Rocks (New Mexico),
gonnardite in Aris complex (Namibia), or assemblages, celestine-thomsonite
veinlets in Fad’yu-Kuda massif (Central Taimyr). In the whole book there are
the data about zeolites from more than 40 alkaline complexes of the world.
