Abstract—A number of examples are considered in which modern arkose sands as well as arkose and compositionally similar sandstones (all of the above rocks are sediments of the first sedimentation cycle) of different ages have definite provenances composed of granitoids of different “geodynamic” types. The main goal of the work is to analyze how the geochemical characteristics of granitoids are translated into petrogenic sedimentary rocks. The comparison of 245 analyses of sands and sandstones with ~375 analyses of the inferred prototype sources of clastic material showed that the lithogeochemical characteristics of arkose and subarkose sands and sandstones (mainly the HFS element content and ratio) makes it possible in most cases to confidently judge the “geodynamic nature” of source felsic igneous rocks.
期刊介绍：
Geochemistry International is a peer reviewed journal that publishes articles on cosmochemistry; geochemistry of magmatic, metamorphic, hydrothermal, and sedimentary processes; isotope geochemistry; organic geochemistry; applied geochemistry; and chemistry of the environment. Geochemistry International provides readers with a unique opportunity to refine their understanding of the geology of the vast territory of the Eurasian continent. The journal welcomes manuscripts from all countries in the English or Russian language.
