During an investigation of the mineralization of the Leadhills- Wanlockhead lead and zinc mining district, rammelsbergite (NiAs2) was identified as an associate of niceolite (NiAs), reputed to have come from no. 4 level on the west branch of the New Glencrieff vein. The identification was confirmed on further material collected from the dumps at the Glenerieff mine, Wanlockhead, Dumfriesshire, and on specimens from the Scottish Mineral Collection (nos. 1952.5.18; 20; 21).

A prospecting method used in 1975 in Greenland and reported briefly on here measures the total cold extractable amount of seven heavy metals, Zn, Pb, Cu, Co, Ni, Sn and Ag. The primary aim of the method is to discover and outline metal anomalies but not to determine their metal content accurateIy. Once an anomaly is targeted this can be done by more detailed foIlow-up surveys. The two areas chosen to test the suitability of the method to Greenland conditions, were the lead-zinc mining district of Mesters Vig on the east coast and the Sorte Engel (Black Angel) mine at MârmoriIik on the west coast. The traverses run show strong anomalies over kriown veins (figs 37 & 38, AA' & CC'; fig. 39, GG' & HH'), as well as indicatingpreviously unknown mineralisation (fig. 38, BB'; the western anomaly in fig. 39, HH').

The genus Bimuria Ulrich and Cooper, 1942, is a biogeographically important member of middle and late Ordovician brachiopod faunas of the Callahan–Gazelle area in the eastern Klamath Mountains of northern California. In middle Ordovician deposits the genus is widespread and ranges from Nevada in the west to southwestern Siberia in the east; however, in late Ordovician beds it was previously known only in Sweden and Northern Ireland. In addition to the northern California occurrence reported here, new late Ordovician occurrences are also noted in east-central Alaska–Yukon Territory and Northwest Territories. Three species of Bimuria are described, including the new species, B. californiensis.A preliminary survey of species described in the literature suggests that the ratio of the length of the dorsal adductor field to the length of the elongate area in the brachial valve decreases from middle to late Ordovician species, and thus may be of biostratigraphic value.

Siberian Department

In 1877, the creation of the West Siberian Department of the Russian Geographical Society in Omsk marked a new stage in the history of scientific study of the Altai Mining District, which was expressed, among other things, in the active expeditionary activities of that time leading scientists to the region. The article analyzes the publication's content of the department's printed organ — «Notes», dedicated to the colonization process and migrations of the second half of the 19th century. The content of the works on the theme, their specificity, and their role in shaping the resettlement agenda are identified. It is emphasized that despite the positive assessment of the role of migration in the development of the Altai territory, experts of the turn of the 19th-20th centuries identified bifurcation points in the work of the «pro-gram» of peasant development of the territory (the relationship with the local Russian and foreign population, the agricultural potential of hotel lacunae, the impact of migration on the scrapping of the type of land use consistent with the natural and climatic conditions of the region, land crowding, rapid plowing of soils, etc.). The article concludes about the unique nature of field materials, their «live» content, the desire for fixation and objectification.
