Description :
For the first time a large-scale geomorphological mapping had been carried out in the course of search for placers| karst landforms and deposits filling karstic hollows were studied, their relative age was determined. Three stages in karstification are distinguished : the Late Miocene-Pliocene, the end of the Pliocene-beginning of the Pleistocene, second half of the Pleistocene, a noticeable deceleration in the process having been traced throughout of the Late Cenozoic. Only karstic-erosional network develops progressively since the Early Pleistocene. Under conditions of limited water supply the conditions do not favour the heavy minerals concentration and placers formation within the karstic-erosional network. - (L'Ed.).
