layers are in hexagonal sequence (ABA or CBC). (Modified from Pósfai, M. & Buseck, P. R. (1998): Relationships between microstructure and composition in enargite and luzonite. American Mineralogist, 83, 373-383.). Fig. 92. Inside showroom in the Department of Mineralogy and Petrology, Hungarian Natural History Museum (TTM), in the building of the former Ludovika Military Academy (1996). Fig. 93. Presentation of a corresponding membership diploma at the meeting of the Section of Earth Sciences of the Hungarian Academy of Sciences (MTA) (György Pantó, ordinary member, to the left, and Péter Árkai, corresponding member, to the right). Fig. 94. Al-site occupancy in K-feldspar megacrysts determined by the (110) method of Kroll and Ribbe. An enlarged portion of the diagram with the plots of the Mórágy area is shown in the right. (György Buda, György Lovas and coworkers, 1999) Fig. 95. Increase in the number of mineral species known from the present-day territory of Hungary. Fig. 96. Hydroxylbastnäsite-(Nd), Merlengo deposit, Zagrad, next to Niksic, Crna Gora, Yugoslavia. A mineral species decribed by Zoran Maksimovic and György Pantó. SEM micrograph. Fig. 97. Pyrite-marcasite disordered structure from the exoskarn of the Recsk deepseated ore deposit. High resolution transmission electron mirograph (HRTEM image, to the left) projected onto [100] and its selected area electron diffraction (SAED) pattern (to the right). Arrows on the HRTEM image indicate the d^oi) (T) and i/(.ioi) (^) units of marcasite in pyrite matrix. The continuous scattering along b* on the SAED pattern indicates structural disorder (István Dódony, 1996). Fig. 98. X-ray powder diffractogram of the corrensite-containing fraction of a dolomitic-marly limestone from the Mecsek Mountains (István Viczián, 1995). Untreated sample (N), sample treated with ethylene glycol (EG), and heated up to 550 °C (550 °C), C1-C6: basal reflections of corrensite, MgCh: Mg-rich chlorite, Ch: chlorite (heated), I: illite. Fig. 99. Galenobismutite, from Rudabánya, polished section, width of field 0.11 mm. On the left: back-scattered electron image (grey: galenobismutite, white: native bismuth (?)); on the right: X-ray image showing the distribution of sulphur (Béla Nagy and Gábor Dobosi, 2000). Fig. 100. Valentinite, bipyramidal crystals, the largest crystal measures 0.3 mm. Rudabánya, Polyánka mine section. (SEM micrograph by Árpád Kovács). Fig. 101. Description of the minerals of Erzsébetbánya* from Gimesi's A Kárpát-övezet ásványainak magyar bibliográfiája [Hungarian bibliography of the minerals of the Carpathian region] (1994). Fig. 102. The Kaba meteorite (from a paper by József Török, 1858). Fig. 103. Aladár Földvári (left) and Kálmán Sztrókay sampling the Kaba meteorite (1963).
