Analysis and Results Comparative analysis of plate igneous rocks of Burmese regions provides a deeper understanding of their nature and formation processes, as well as the associated mineralization. Comprehensive consideration of this problem is a very topical task of fundamental research and has practical significance in connection with the development of mineral derivatives of rare, rare and rare earth metals among the products of plate magmatism. Alkaline-basaltoid dyes and blast tubes, which have well-defined geological positions and are often systematically combined with ore formations, can contribute to the identification of many problems in the genesis and chronological sequence of different ores in the region. Many questions of plate plate magmatism for the Chakilkalyan mountains, including the geochemical and metallogenic specialization of alkaline basaltoids and lamprophyre formation rocks, which are important for predicting gold and rare metal mineralization, remain unresolved. The purpose of this study is a detailed description of the rocks of the formation of alkaline basaltoids and lamprophyres (petrographic, petrochemical, mineral- accelerator and geochemical) and its conclusions on the potential mineralization of plate magmatism. The rocks of the formation of alkaline basaltoids and lamprophyres at the boundary of the yacht area were represented by kersantites, spessartites, vogezites and diorite porphyrites associated with them paragenetically, as well as the most recent kamptonites and monchikites. For dyke, virtually all types of rocks are characterized by the presence of a number of elements (Au, Ag, W, Mo, Se, Te, Bi, As, Sb, Re, Hf) with higher amounts than clarkes [7]. The range of change in clark-concentration of individual elements for rocks of formation of alkaline basaltoids and lamprophyres of the yacht area is as follows: Te - 56-110; Se – 2,8-82,2; Au – 6,8-28,8; Bi – 4,6-24,4; As – 9,07-10,7; Ag – 4,7-10,0; Sb – 3,6-10,0; Re - 1,5-10,5; Hf – 3,3-6,0; W –1,8-3,6; Mo – 1,2-3,7. The geochemical sequence (Te-Se-Au-Bi-As-Ag-Sb-Re-Hf-W-Mo) of the rate of accumulation of the main elements in the ore-generating magmatic products of the formation of alkaline basaltoids and lamprophyres contributes to the geochemical specialization and less clearly indicates that it has a mineralization. |
