PROCESS OF SEARCH FOR PRIMARY DEPOSITS OF DIAMONDS AND EVALUATION OF THEIR PROGNOSTIC PARAMETERS

摘要

FIELD: search for primary deposits of diamonds. SUBSTANCE: kimberlite pipes discovered earlier are brought out to prognostic geological chart ( map ) and grids of stresses of rotational field of the Earth are superimposed on them with subsequent referencing of promising sections of manifestation of kimberlite magmatism to structural nodal points with use of schlich-minerological, geophysical, geological and geochemical criteria of manifestation of primary diamond- bearing capacity. First genetic groups of comagmatic pipes are exposed. Structural constructions per each exposed group are carried out with subsequent correlation of these structures with elements of breaking tectonics and present-day hydraulic network. Positions of local promising sections per each exposed group are determined. Established behavior in their change for known kimberlite pipes of this kimberlite field are utilized for evaluation of prognostic parameters of primary deposits of diamonds. EFFECT: raised authenticity and precision of search for primary deposits of diamonds. 2 dwg
