查明黔西南贞丰等地冰洲石矿床的成矿温度为１２６～１６０℃，成矿压力为（２６０～５２０）×１０５Ｐａ；成矿流体盐度（ＳＮａＣｌ）为１２．２％～１９．６％。研究了不同成矿阶段方解石、冰洲石的氢、氧、碳同位素组成及变化特征：其中冰洲石成矿阶段δ１８Ｏ值为１６．２４～１８．４８‰，平均１７．３６‰；Ｗ／Ｒ为０．１６～０．１８。而从薄层方解石阶段到冰洲石成矿阶段δＤＨ２Ｏ＝－４９～－６８‰。δ１３Ｃ（ＰＤＢ）＝－０．６０～０．７３‰，δ１３ＣＣＯ２（ＰＤＢ）为－０．３７～２．４３‰。计算出δ１３Ｃ∑Ｃ＝－２．０８～－２．４９‰。研究表明成矿流体来源于大气降水与加热的地下水的混合，碳来源于地层。探讨了冰洲石成矿时特定的物理化学条件及地质环境。
It is found that the mineralization temperature of the iceland stone deposits in Zhenfeng and other places in Qianxinan is 126 ~ 160 ℃ and the metallogenetic pressure is (260 ~ 520) × 105Pa. The SNaCl of the ore-forming fluid is 12.2% ~ 19. 6%. Hydrogen, oxygen and carbon isotopic composition and variation characteristics of calcite and icebergs in different metallogenic stages were studied. The δ18O values of the mineralogical stages were 16.24 ~ 18.48 ‰, with an average of 17.36 ‰. The W / R 0.16 ~ 0.18. However, δDH2O = -49 ~ -68 ‰ from thin calcite to iceland mineralization. δ13C (PDB) = - 0.60 ~ 0.73 ‰, δ13CCO2 (PDB) -0.37 ~ 2.43 ‰. Δ13CΣC = -2.08 ~ -2.49 ‰ was calculated. Research shows that the ore-forming fluid is derived from the mixing of precipitation and heated groundwater, with carbon originating in the formation. The specific physico-chemical conditions and geologic environment during ice mineralization were discussed.
