The conference was dedicated to the memory of famous Polish geologist, petrographer, and mineralogist Joseph August Morozewicz (1865–1941), who made important contributions to the investigation of alkaline rocks. During the period 1898–1908, Morozewicz carried out investigations in the Azov region. He discovered and described (in papers in German, Polish, and Russian) the alkaline rocks of the Mariupol area, in particular mariupolites, albite–nepheline rocks. He found the new minerals taramite and beckelite (synonym of britholite-(Ce)) and determined a first composition for nepheline, known today as Morozewicz nepheline (Ne68Ks22Q10) [Elements, Vol.5 (6), 2009].
At 1929 Morozewicz published book Mariupolit i jego krewniaki = Mariupolite et ses parents(Mariupolite and its relatives in Polish and French). He described there rocks of the area: mariupolites, foyaites, syenites, pyroxenites, pegmatites and granites.
On the map attached to the book, polish names are present. Mitrowka is called today Dmytriivka, Donske village is located between Sretenka and Apostołowka, near the big, blue spot of mariupolites, Lazarivka is located between Sretenka and Archangiełka, along the stream Lisica (mariupolites with magnetite) and river Wali-Tarama (taramitic foyaites), and Khlebodarivka quarry is located on the left edge of the map (marked with small triangle, left from Archangiełka village).

Zirconium is a chemical element with symbol Zr and atomic number 40. The name of zirconium is taken from the name of the mineral zircon, the most important source of zirconium. The word zircon comes from the Persian word zargun زرگون, meaning “gold-colored”.Zirconium is a lustrous, grey-white, strong transition metal that resembles hafnium and, to a lesser extent, titanium.
The principal commercial source of zirconium is zircon [ZrSiO4]. As of 2013, two-thirds of zircon mining occurs in Australia and South Africa. Zircon resources exceed 60 million tonnes worldwide and annual worldwide zirconium production is approximately 900,000 tonnes. Zirconium also occurs in more than 140 other minerals, including the commercially useful ores baddeleyite [ZrO2] and kosnarite [KZr2(PO4)3].
