Use of vertical zonality of primary halos in estimation of erosional cut of tin ore bodies of Primorye region

Abstract

According to the nature of changes in the relations of productivity of the main ore elements of sulfide-cassiterite deposits of the Miao-Chan Ridge from the center to the upper edge of ore bodies and the degree of remoteness of these bodies from small hybrid intrusions, with which tin mineralization is closely associated, it is possible to estimate the cut-off levels of ore bodies.
