TsNIGRI website posts online version of“Ores and Metals” journal (№ 1/2020)

In 2020, the first issue publishes an overview of the journal founder, Central Research Institute of Geological Prospecting for Base and Precious Metals, established 85 years ago.

“Applied metallogeny” section presents a paper by A.I. Chernyshov, I.Yu. Loskutov and E.E. Pugacheva, “Forecast estimate of ultramafite chromite potential within Baikal-Muisky ophiolite belt”. The authors used an unconventional petrochemical method to estimate chromite potential of Paramsky and Shamansky massif ultramafites in northeastern Baikal region and obtained encouraging results.

“Deposit forecasting, prospecting, assessment and exploration methods and techniques” section comprises three papers; all of them will certainly be of interest to specialists. The first paper deals with experience of using polymetallic deposits' geochemical models in mineralization forecast estimates. Based on the original data obtained in the study of porphyry copper, stratiform lead-zinc, gold and pyrite-polymetallic deposits of the Russian Rudny Altai, S.A. Milyaev (TsNIGRI) shows significant potential for using geochemical deposit models to improve reliability of mineralization forecast estimates; he also points out study challenges. V.N. Nesis, A.P. Motov and A.V. Butnyakov, authors of the second paper, “Geochemical features and boundaries of gold fields within Gornyachka and Peschanoye deposits area, North Urals”, present the data on prospecting and exploration (2016-2018) performed in the central segment of East Tagil structural-formational zone (30 km2). The third paper (by R.F. Salikhov, A.V. Tolstov, V.V. Salikhova and A.N. Kuzmenok) reviews an efficient technique to reconstruct paleotopography of kimberlite-hosting socle. Its use allows researchers to get the best idea in prospecting for buried primary diamond deposits.

Relevant studies focused on ore deposit structure are represented by two papers. One of them, “Native gold typomorphism as an indicator of various mineralization styles at the major skarn-porphyry Au-Fe-Cu Bystrinskoye deposit, East Trans-Baikal region” (authors: G.D. Kiseleva, Yu.I. Yazykova and V.A. Kovalenker), provides a detailed analysis of extensive data and discusses gold distribution in the deposit ores; gold is among the top economic metals there. The other paper, “Au-Pd-Cu-Se-U mineralization of Svetloye orebody, Central Karelia” (authors: L.V. Kuleshevich and O.V. Lavrova), provides new diverse data on the orebody discovered in the late 20th century (rock age, mineral and mineralogical composition as well as micromorphology); its genesis is of special interest to specialists.

“Rock and ore mineral composition and properties” section publishes results of a joint study carried out by I.S. Barmin, V.V. Morozov and V.V. Polivanskaya; they validate a set of reagents to thicken and deflocculate slime classes of stale tailings in flotation. A paper by A.A. Veselovsky and S.A. Laikhan deals with technologies involved in complex utilization of nickel slag; it is published in the same section.

“Geologists’ war memories” section devoted to the 75th anniversary of the Victory Day starts publishing selected chapters from “Remote voices” book by A.A. Konstantinovsky; real life of a Moscow family in autumn 1941 is described. These memories will deeply impress any reader.
