主　　题：A Study on the Behavior of Mercury in Weathering Environment in Wanshan District 

摘      要：Studies on the mechanism of supergenic dispersion, migration and enrichment of mercuryand other elements in strata-bound ore deposits are of great importance both in theory andin practice. In special reference to the Wanshan mercury ore deposits, this paper discusses themechanism of supergenic migration of mercury and the associated elements lead, zinc, antimony,etc. In this paper the focus of the discussion is placed on the existing forms of mercury, therules governing the migration and enrichment of mercury and associated elements in the processof weathering and some aspects of the simulating experiments on weathering of carbonaterocks. Three existing forms of mercury are recognized in carbonate rocks. The migration of met-cury together with the associated dements in the process of weathering follows the sequence:SiO;→Pb→Hg→Sb→Zu. The results of simulating experiments on weathering of car-bonate rocks show that weathered materials contain more mercury and associated elementsthan the original rocks.
