Based on the values of δ~(34) S of the sulfide minerals collected from YangChuling W(Mo) deposit in Jiangxi province, we have deduced the ore-formingconditions and the sulfur origin.

The stability field of the various complexing forms of alumi-num in hydrothermal solution shows that Al~(3+) has been combined mainly with OH~- to form hydroxylic complexes, if we do notconsider the presence of other anions in the system. However Al~(3+) hasbeen combined mainly with F~- to form various Al-F complexes, if it ispresent a lot of F~- in the system, and there is suitable alkalinity and tem-perature. The stability field of Al(OH)_3 and AlF_6~(3-) is mid-high tempera-ture and inter mediate-alkalic...

The stability field of the various complexing forms of alumi-num in hydrothermal solution shows that Al~(3+) has been combined mainly with OH~- to form hydroxylic complexes, if we do notconsider the presence of other anions in the system. However Al~(3+) hasbeen combined mainly with F~- to form various Al-F complexes, if it ispresent a lot of F~- in the system, and there is suitable alkalinity and tem-perature. The stability field of Al(OH)_3 and AlF_6~(3-) is mid-high tempera-ture and inter mediate-alkalic area.

热液体系中铝的各种络合形式的稳定范围表明:若不考虑体系中其他阴离子的存在,则热液中的Al~(3+)主要与OH~-结合,形成各种羟基络合物;若体系中有大量F~-存在,并且具合适的碱度和温度,则Al~(3+)主要与F~-结合,形成各种Al-F络合物。Al(OH)_3和AlF_6~(3-)的稳定场是中高温-中碱性区。
