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.
