...Kreshimir N. Malitch; Oskar A.R. Thalhammer Abstract Combined structural, compositional and osmium-isotope data on selected Pt–Fe nuggets from economically important placer deposits closely linked to clinopyroxenite–dunite massifs of the Siberian Platform (Kondyor, Inagli, Guli) and the Middle...

... were first recognized by Rozhkov et al. (1962) as the Aldan (Inagli) type of platform platinum deposits. Later, Cabri and Naldrett (1984) referred them to deposits of the specific Inagli subtype localized, along with platinum deposits of the Alaskan (Uralian) subtype, in zonal ultramafic massifs...

... of amphibole in the syenite of the Lunnoe deposit (143.1 ± 2.0 Ma) and in the clinopyroxenite of the Inagli massif (142.4 ± 2.0 Ma) and the formation of most of the alkaline rocks of its ring framing also took place at this stage. At the Samolazovskoe deposit, this stage is marked by the formation of zircon...

.... This zone also includes the Inagli mica and Cr-diopside (“Siberian emerald” ( Korchagin, 1996 )) deposit. In the northwest, in the endocontact zone of the massif, there are ultrabasic sills consisting of olivine, diopside, and phlogopite. Some researchers ( Bogatikov et al., 1991 ; Vladykin, 1997 ) assign...

... Tagil type of platinum deposit is convergent with the Inagli type, which occurs in a zone of late Mesozoic tectono-magmatic activity in the Aldan shield. All the massifs whose primary platinum content is genetically related to forsterite dunites yield placer deposits. The assemblages of platinum-group...

Druzhinina Abstract Placer deposits in the Siberian platform are closely associated with well-known platiniferous intrusions (Kondyor, Inagli, Noril’sk, Chiney, and Guli) but there are also abundant platinum-group mineral (PGM) placers of large...

... development area. The central part of the Inagli massif formed by dunites was eroded, thereby forming a depression that lies at the base of the Inagli platinum placer deposit. Fig. 2.

.... This is clearly shown on the example of high-titanium Cr-spinels of the Carnian stage from the diamondiferous ore deposit Bulkur River ( Nikolenko et al., 2018 ). Mues-Schumacher et al. (1995 , 1996 ) suggested that the primordial melt of dunites of the Inagli massif corresponds to a potassium picrite...

... of high-Mg olivine and chromite in an intermediate chamber could produce cumulative dunites similar to those of the Inagli intrusion. Crystallization of olivine and chromite was followed by cotectic crystallization of olivine and clinopyroxene, then that of clinopyroxene and phlogopite, and, finally...

... rocks and Cr-diopside veins indicate a genetic similarity of these rocks and the Inagli massif formed from high-K picritoid melts. Nikiforova et al. (2018) considers the indicative features of placer gold used for the prediction of the formation types of gold deposits in the east of the Siberian...

Compositional variation and temperature range of alloy genesis decrease in the order from Goodnews Bay and Inagli to Galmoenan...

Note that the well-studied alkali-ultramafic massifs in southeastern Russia (Inagli, Konder, Feklistov, and Chad) are isometric bodies with subvertical contacts and an intricate zoned-ring structure. In their cores...

Cuproiridsite and malanite were found in the Konder and Inagli placers on the Aldan Shield, with cuproiridsite being predominant in Inagli. Only placers of Columbia were found to contain all three end...
