Analysis of materials of the State Geological Map 1 : 1 000 000 (3rd generation) for the southern Sakha–Yakutiya territory in the course of compilation of the Minerogenic forecast map of the Russian Federation and its continental shelf, 1 : 2 500 000, and of the Map of the distribution regularities and forecast for porphyry goldcopper, large-tonnage black-shale gold, and epithermal gold deposits of the Russian Federation, 1 : 2 500 000, has allowed the authors to substantiate distinguishing the new Aldan-Vilyui ore-placer gold-bearing province with a total area of 450 000 km2 in the basins of the Lena, Aldan, and Vilyui rivers. The authors estimate the metallogenic potential of the province at 5000 t of gold. In the near future, this province may become a new extensive resource base of gold and related elements for the Russian Federation.

Some geological engineering problems are caused by weathering of black shale within dispersed sulfide minerals (mainly pyrite), in which some weathering products such as acid water and expansive sulfates play an important role. These effects are essentially manifested through oxidation of sulfide minerals. Complex chemical reactions occur simultaneously and influence mutually in water-rock interaction process. Chemical weathering of black shale is a factor leading to engineering problems such as landslides and acid corrosion. The objectives of present study are to understand the process of water-rock interactions between black shale and water. The semi-immersion simulation experiment is mainly used to explore the chemical weathering characteristics of black shale under natural conditions.
