title: THE NEW DATA ABOUT GENESIS OF TIN PLACERS IN THE NORTH-WESTERN PART OF THE UKRAINIAN SHIELD
abstract: In connection with that in Ukraine tin deposits are not mined, an important problem is the research of new tin-bearing objects, to that Perha columbite-cassiterite placers belong. On the basis of long-term experience of metallogeny works, that is conducted in the department of geology of minerals in Institute of Geological Sciences of NAS of Ukraine, paleogeomorphological method and structure-lihtological modeling the interpretation of geological information is executed and trends of cassiterite
