In this paper, we provide characteristics of sulfates of exhalation origin—langbeinite K2Mg2(SO4)3, two modifications of calciolangbeinite K2Ca2(SO4)3 (new data), and vanthoffite Na6Mg(SO4)4 (first mineralogical data for this genetic type)—from active fumaroles of the Tolbachik volcano in Kamchatka. These minerals are associated with anhydrous copper sulfates and arsenates, minerals of the aphthit...... hiện toàn bộ
Silver-cobalt mineralization in the Upper Seymchan ore cluster, Northeastern RussiaPleiades Publishing Ltd - Tập 56 - Trang 322-345 - 2014

This paper is focused on the Early Cretaceous Ag-Bi-Co-sulfoarsenide mineralization atypical of northeastern Asia, which contains diverse Co-Ni sulfoarsenides, Se-bearing Bi sulfotellurites, and Ag-Bi-Pb sulfosalts. The Upper Seymchan ore cluster is located at the boundary between the Paleozoic Omulevka Terrane of carbonate platform and the In’yali-Debin Synclinorium of the Kular-Nera Terrane.

Lahnsteinite, Zn4(SO4)(OH)6 · 3H2O, a new mineral from the Friedrichssegen Mine, GermanyPleiades Publishing Ltd - Tập 55 - Trang 663-668 - 2014
N. V. Chukanov, R. K. Rastsvetaeva, S. M. Aksenov, I. V. Pekov, D. I. Belakovskiy, G. Blass, G. Möhn
A new mineral, lahnsteinite, has been found in the dump of the Friedrichssegen Mine, Bad Ems district, Rhineland-Palatinate (Rheinland-Pfalz), Germany. Lahnsteinite, occurring as colorless tabular crystals in the cavities of goethite, is associated with pyromorphite, hydrozincite, quartz, and native copper. The Mohs’ hardness is 1.5; the cleavage is perfect parallel to (001). D

Kizilcaören ore-bearing complex with carbonatites (northwestern Anatolia, Turkey): Formation time and mineralogy of rocksPleiades Publishing Ltd - Tập 56 - Trang 35-60 - 2014
A. V. Nikiforov, H. Öztürk, S. Altuncu, V. A. Lebedev
The results of isotope-geochronological and mineralogical studies of the rocks making up the Kizilcaören fluorite-barite-REE deposit, northwestern Anatolia, Turkey are discussed in the paper. The ore is a constituent of the subvolcanic complex localized in a large fault zone. The complex combines (from earlier to later rocks): (1) phonolite and trachyte stocks, (2) carbonatite and carbonate-silica...... hiện toàn bộ
