An unsupervised neural network technique, Growing Cell Structures (GCS), was used to visualize geochemical differences between sandstones of four different sedimentary provenance groups: P1 (mafic), P2 (intermediate), P3 (felsic), and P4 (recycled). Multidimensional data of four sandstone data sets comprising major elements, log-normalized major elements, trace elements, and high field strength elements...
The Chinese Altai is a typical part of the Central Asian Orogenic Belt (CAOB), but its tectonic evolution is not well understood. Geochemical study of Early Paleozoic metasedimentary rocks was conducted to better constrain their provenance and tectonic environment. These rocks have relatively low CIA values (49 to 79), with ICV values (0.73–1.36) higher than that of post-Archean Australian average...
