Estimation of residual prospects of Alexandria ore district by remote sensing materials
- Authors:
- Yu. N. Serokurov
The possibilities of using space sounding materials to assess the residual prospects of the Alexandria district with the colliery mineralization are considered. The data on its genesis and structural forms of control were used as a basis. The materials were processed by various methods, informative features were identified, and prognostic and prospecting models were formed, which made it possible to assess the prospects of the area.

Geological-genetic models of formation of gold and silver deposits of Verkhoyansk fold-overthrust belt
- Authors:
- V. Yu. Fridovskii
- G. N. Gamyanin
The geological and genetic models of noble metal deposits of the Verkhoyansk fold-overthrust belt formed in different geodynamic conditions are considered. The main stages of deposit formation are outlined based on the geological-structural and mineralogical-geochemical data.

Genetic basis for the development of criteria of diamondiferous kimberlite bodies
- Authors:
- A. V. Kozlov
- Yu. S. Korobeinikova
The model of formation of pipe-like kimberlite and lamproite bodies, which is based on the fluid dynamic regime of development of magmatic paleosystems, is developed. The main factors determining the fluid dynamic regime of formation of kimberlite bodies are formulated. The proposed model satisfactorily explains many morphological features of kimberlite systems represented by dykes, pipes and sills, peculiarities of the internal structure of kimberlite bodies composing them and may serve as the basis for developing criteria of their diamond potential.

Development of the theory of ore genesis and prognostic and prospecting models for gold, platinum, copper, and nickel for greenstone complexes of Karelia
- Authors:
- A. K. Korsakov
The spatial and genetic relationship of mineral deposits and ore occurrences with the geodynamic complexes of the Late Archean and Early Proterozoic greenstone belts of Karelia are considered. On this basis the place of ore-forming processes at certain stages of formation of greenstone belts is determined.

Structural and geodynamic reconstructions, modes of industrial ore formation and prognostic and prospecting models of noble metal deposits in Northeast Asia
- Authors:
- V. Yu. Fridovskii
The evolution of the types of gold-quartz mineralization at the accretionary stage of the region's development is shown: from stratified metamorphogenic in the rock fall zones to vein-vein deposits of mineralized crush zones. For each type of mineralization data on the position in the regional structures, vertical mineralogical and geochemical zoning and physical and chemical parameters, geochemistry of stable and radiogenic isotopes, etc. are given. The system of factors determining the formation of each type of mineralization and their use to assess the industrial-resource potential of the region is proposed.

Onboard video spectral equipment for exploration forecasting
- Authors:
- K. N. Chikov
- V. V. Gud
- V. M. Krasavtsev
A concept of an improved ultraviolet video spectrometer designed for installation onboard aircraft and satellite is proposed. An instrumental design of a two-component system containing input optics (projecting lens) and spectrometer optics (polychromator) is presented. It is shown that the concentric arrangement of the entrance and collimator lenses has a number of significant advantages over traditional optical schematic solutions.
