Petrochemical and geochemical characteristics of the dike series in the northern part of the Chakylkalyan megablock (Southern Uzbekistan)

The article discusses the results of petrochemical and geochemical studies of the dike series in the northern part of the Chakylkalyan megablock. Three main types of dike series have been identified: granitoid (aplite-like granite-porphyry, leucogranite, fine- grained granite, granodiorite porphyry) - lamprophyric (kersantite, spessartite, vogesite in association with diorite porphyrite) - alkaline basaltoid (camptonite, monchikite). It is shown that a characteristic feature of the geological structure of the ore field is the close paragenetic connection of mineralization by rocks of the dike complex.
