الوصف: | Рассматривается происхождение алмазов в метеоритах, взрывных кольцевых структурах, кимберлитовых и лампроитовых трубках на платформах, делается вывод об образовании гигантских кристаллов алмаза в кимберлитовых и лампроитовых трубках за счет собирательной перекристаллизации алмазных агрегатов типа карбонадо. ; Diamond content of the Earth is genetically connected with the flows of the fluids, which emanate from its liquid nucleus, by which the explosive earthquakes and deep magmatism are created. Fluid explosions on the platforms are timed to the annular structures usually in the framings of raisings of their crystalline foundation. By blast wave in them are created the smallest grains of diamond (in the paragenesis with the Lonsdaleite) in the partially molten and crushed rocks, which were ejected to a high altitude and returned to the annular structures and their environments. The diamond of jewelry quality was crystallized under the pressure, which corresponds pyroxenitic and eclogitic (upper) zones to the enormous depths of mantle in the magma chambers, stratified to the peridotitic (lower). During the crystallization under the action of trans-magmatic fluids the diamond seized the rock-forming minerals, on which will recognize its genetic types peridotitic, pyroxenitic, eclogitic. In spite of enormous depth of penetration, the centers of diamond-bearing magmatism were developed in connection with the eugeosynclines, from which began the formation of the Archaean crystalline foundation of platforms. Deep magmas intruded in them with the formation of Archaean diamond-bearing intrusions, but their structural connections with the deep centers remained for the course of entire geological history. Its periodically were renewed as the source of the deep fluids, which generated kimberlitic magmatism. Kimberlitic magmas were developed with the substitution of Archaean species with the retention of their ribs and the inheritance of diamond mineralization. At the front of substitution the grainy concretions of diamond, ... |
