Zimneberezhny area of Arkhangelsk region has a sufficient ore raw mineral potential and big prospectiveness for exposure of industrial diamondiferous pipes. In connection with it, there rises a question about the development of a new technology of native diamond deposits exploration, which contain both traditional and alternative methods and approaches.
Accordingly, there was developed a programm, which forsees the dividing of work to two consecutive stages. On the first stage, the experimental and methodological operations were held on the standard areas with usage of all complex of exploration methods. Later on, on the basis of this, the exploration works technology for diamonds on the prospective areas were held with the ranking of objects on their significance.
The following researchings are need to be held on the stage of detection of exploration works.
1. Distant research methods: researchings with using the multispectral space surveys: complex airborne geophysical (magnetic and electromagnetic) survey.
2. Geophysical researching: extraction of prospective objects on the potential fields data; resonance and acoustic profiling; areal electrotomography.
3. Geochemical researching: geochemical operations by method of passive adsorption of soil and ground air; complex geochemical researchng (geoelectrochemistry, atmochemistry on free and sorb gases).
Evaluation of the prospects of the potentially diamopndiferous area within the limits of researched area, using the expsed forecast criteria, will make a significant economic effect, during the prospective planning of a geological and exploration works in the region.
