SREBRENICA OREFIELD, PODRINJE METALLOGENIC DISTRICT, REPUBLIC OF SRPSKA, B&H: HYDRATED Fe(Al)-PHOSPHATES AND THEIR PARAGENESES WITHIN THE Pb-Zn MINERALIZATION
The Srebrenica orefield is mostly composed of Tertiary dacite-andesites, and quartz latites, pyroclastites, Paleozoic schists, and Quaternary sediments, but in a in a lesser extent. The latest research showed that in the Srebrenica orefield occur complex mineral parageneses and associations deposited in pneumatolytic-hydrothermal and hydrothermal (...
