Heavy minerals in sedimentary rocks are important in provenance studies. In the present area there are sandstones with several heavy minerals such as Cr-spinel, garnet, zircon, tourmaline, rutile and so on. Possible thesis will focus on some of these minerals:

1. ZTR group with chemical and radiometric dating analyses of zircon and rutile and chemical analyses of tourmaline
2. Garnet, chemical analyses of major and trace element
3. Spinel, chemical analyses
