摘　　要：凤凰山 Ag-Mn 矿床中的低铁硫锰矿是主要载银矿物之一。矿物的化学成分、硫、铅同位素及物性等标型特征的研究,为该矿床提供了中低温岩浆热液型,成矿物质来自寒武纪地层的成因信息。硫锰矿的富集程度,其中的 Fe/Mn,Ag/Pb 比值,及其物性标型、标型矿物组合等特征,均可作为银矿化的找矿标志。Alabandite with low amount of Fe is one of the major Ag-carrier minerals,in Fenghuangshan Ag-Mn deposit.Based on its typomorphic characteristics of chemical composition, sulphur-isotope,lead-isotope and physical properties and so on,it is provided the genetic informa- tions such as:this deposit belongs to the type of medium-low temperature magmatic hydrothermal and its ore-forming material come from Cambrian stratum etc.Enriching degree of alabandite and the mineral paragenetic association relative with it and Fe/Mn ratio and Ag/Pb ratio in alabandite and its physical properties can be used as the ore guide of prospecting.
