The Jõhvi magnetite quartzites (MagQ) occur as subvertical beds with a complicated structural outline in biotite-garnet-cordierite and pyroxene gneisses which in places also contain high concentrations of iron. Drill core study shows that the comp

The Estonian Precambrian crystalline basement that consists of Paleo- to Meso-Proterozoic metamorphic and igneous rocks is covered by a 100-780 m thick deposit of Paleozoic sedimentary rocks. Thus, the basement is unavailable for direct surficial obs
