摘要：
Modeling of the mineralizing process at the Shangmanggang Carlin-type gold deposit by CHILLER accurately reproduced both the paragenetic sequence of syn-ore alteration assemblages and the proportions of mineral assemblages. Input parameters were the chemical composition of the ore-hosting rocks, dolomite from Sazipo Formation (P-1s) and sandy mudstone from Mongga Formation (J(2m)). The modeling path comprises isothermal dilution (Stage I dilution and quenching) - isothermal reaction with host rocks (Stage II Ore-forming fluid/dolomite interaction-isobaric cooling (Stage III cooling) - isothermal reaction with host rocks (Stage IV interaction of the ore-forming fluid with the sandy mudstone) - isobaric cooling upon opening of the system (Stage V).
