The work on the frame lithological and structural modeling of the Tokko and Roman deposits has been completed
CMT Consulting has completed work on the skeleton lithological and structural modeling of the Tokko and Roman deposits, which are located close to each other within the eastern part of the Olekmo-Charsky highlands in southwestern Yakutia.
The work area is characterized by a mid-mountain relief with maximum elevations up to 1400 meters above sea level. The permafrost in these places can reach 500 meters.
The deposit massif is composed mainly of Archaean plagiogneisses, and dike-like bodies of dolerites and amphibolites are found. The rocks are heavily worked by hydrotherms and have undergone metasomatosis. From above, the rocks are overlain by a cover of Quaternary sediments of various origins. Structurally, the deposit is located at the intersection of the Kondinsky fault system of the east-northeast strike and the Tokkinskaya submeridional with a large number of feathering cracks. The former are represented by a series of gentle surges of small amplitudes. The second – reset-shifts are slightly steeper. The host rocks are severely disturbed, which primarily affects the endurance of dolerite and amphibolite bodies. The surges of the Kondinsky system are traced by strong metasomatic changes.
The SMT specialists analyzed extensive geological and geophysical data from high-quality exploration work, conducted a structural analysis, modeled geological bodies and rock changes, built a structural skeleton of the deposit with associated faults and fault zones both with each other and with the resource model, and recommended sites for further exploration of the massif.
