摘要
为了查明 10 0号矿体成矿溶液的性质 ,我们测定了样品中锡石和石英的氢、氧同位素组成 :δD石英 =- 11.8‰~ - 73.1‰ ,δ1 8O石英 =13.6‰~ 16 .2‰ ;δD锡石 =- 5 5 .8‰~ - 132 .3‰ ,δ1 8O锡石 =4.9‰~ 6 .6‰。综合分析相关的数据表明 ,10 0号矿体的成矿溶液是以岩浆水为主 ,加入了大气降水等其它混合水。
In order to research the ore fluid of No. 100 orebody, hydrogen and oxygen isotope compositions of cassiterite and quartz were measured. The results are shown as following: δ D(Quartz)=-11.8‰~-73.1‰,δ 18O(Quartz)=13.6‰~16.2‰;δD(Cassiterite)=-55.8‰~-132.3‰,δ 18O(Cassiterite)=4.9‰~6.6‰. Analysing the relevant data show that the ore fluid of No. 100 orebody is mixed by magmatic water and other waters such as meteoric water.
