Bulgarian Mineralogical Society www.bgminsoc.bg ACTIVITIES HISTORY The BMS organizes annual meetings, either on its own or jointly Have you heard of the International Conferences on Mineralogy and with the BGS. General meetings take place every three years. Both Museums? If you have not, the next one (MM9) is being organized by Bulgarian nationals and foreign scholars who have made significant the Bulgarian Mineralogical Society (BMS) and will take place 5–7 July contributions to the advancement of mineralogy in can 2020 at the Earth and Man National Museum in (Fig. 1). The BMS be elected as honorary members of the society. Preparations are (Българско минералогическо дружество) is one of the oldest members of the currently underway for MM9 (http://www.bgminsoc.bg/wp-content/ IMA: two of its members attended uploads/2019/06/MM9Circular1Web.pdf). (Tune in regularly for the inaugural IMA meeting in COVID-19 related updates!). The scientific program will include four Zürich (Switzerland) in 1959. The sessions: Mineralogical Research and Museums; Archaeomineralogy eminent Bulgarian mineralogist and Cultural Heritage; Collection Management and Development; (1913–2004) served Museums, Environment and Society. as a national representative in the Members of the BMS have been principally responsible for the systematic IMA from 1959 to 2004, further regional study of Bulgarian mineralogy, as well as of crystal morphology contributing as a councilor (1970– and the chemistry of different ore and associated minerals. Among 1974), vice-president (1978– these, of major importance to Bulgaria, has been the study of Cu–Au 1982), president (1982–1986) deposits in the Srednogorie Zone and of the Pb–Zn deposits in the and past-president (1986–1990). Rhodope Mountains. To date, some 500 minerals, including 11 new th Bulgaria hosted the 13 IMA species, have been identified in Bulgaria. A few of these new discoveries General Meeting in the beautiful remain unique. Other “Bulgarian” minerals, such as strashimirite seaside city of Varna in 1982. [Cu8(AsO4)4(OH)4·5H2O] and kostovite (CuAuTe4), have since been The Bulgarian mineralogical reported from many other places around the world. During the 1980s, community has made significant Bulgarian mineralogists, led by I. Kostov, were involved in a major contributions to the activities of Earth and Man National collaborative program with their Russian colleagues (D.P. Grigoriev, N.Z. Figure 1 Museum, Sofia. various IMA commissions and Evzikova, and others) aimed at establishing how spatial and temporal working groups. changes in crystal morphology were linked to the natural processes The BMS was founded as an independent professional organization on of crystal nucleation and growth. The outcome of this program was 21 February 1990 in Sofia. Prior to that, mineralogists, as well as some the recognition of evolutionary trends in crystal habits peculiar to geochemists and petrologists, had been an active group within the individual mineral bodies, deposits, and ore fields. These ideas were th Bulgarian Geological Society (BGS) (www.bgd.bg) in its Mineralogical initially reported at the 13 IMA meeting in Varna in 1982. Section. For example, the first President of the An essential part of current BMS activities is the publication of BGS, elected in 1925, was the pioneer Bulgarian Geochemistry, Mineralogy and Petrology (ISSN 0324-1718), which in 1975 mineralogist and petrographer Georgi N. succeeded the Bulletin of the Geological Institute, Series Geochemistry, Bonchev (1866–1955) (Fig. 2), who also served Mineralogy and Petrography. It is a nonperiodic journal, which is as Rector of (1914–1915). One distributed in some 30 countries by the library exchange department of his greatest contributions to the advancement of the Bulgarian Academy of Sciences. of mineral sciences in Bulgaria was writing the first university textbooks on mineralogy, BULGARIA’S HERITAGE crystallography, and petrography in Bulgarian. Besides the two national museums Classification of minerals on a geochemical and mentioned above, both universities crystal chemical basis was the backbone of Ivan and research institutes house Kostov’s 1957 textbook Mineralogy, its subsequent mineral collections representing 1973 and 1993 editions, and its translation into Georgi Figure 2 Bulgarian and foreign localities. English in 1968 and Russian in 1971. Bonchev Thanks to the discovery of The BMS membership has, over the years, remained at a roughly emeralds (Fig. 4) and other rare 50 professionals (mineralogists, crystallographers, geochemists, minerals, the Urdini Ezera site in the Rila Mountains was declared petrologists, and mineral deposit geologists), as well as some amateur Beryl (emerald) from the Figure 4 mineral enthusiasts. Most of the professional members are affiliated a national mineralogical reserve Urdini Lakes area of the with universities or institutions of the Bulgarian Academy of Sciences in 1984. Because Bulgaria is Rila Mountains.

Academician Ivan Solnitsata (from six millenia ago), the world’s oldest gold treasure in Kostov (Fig. 3) was elected the first President the Varna Necropolis, plus gold- and graphite-decorated pottery and (1990–1995) and Honorary President of the other artifacts from a variety of prehistoric sites. Do not miss your BMS. Several other mineralogists served as its opportunity to see Bulgaria’s mineral heritage and its extraordinary presidents later on, and two of them – Jordanka history. We look forward to seeing you at MM9! Mincheva-Stefanova and Dobrinka Stavrakeva Ruslan I. Kostov ([email protected]) Ivan Kostov Figure 3 – were also elected as its honorary presidents.
