石膏（CaSO 4中心点2 H（2）O）是一种含有结晶水的水合矿物，也称为石膏水合水（GHW）。我们确定了同位素分馏因子（α O-17，α O-18和α D）之间的GHW和自由水的母液在温度范围从3摄氏度到55摄氏度在不同的盐度和沉淀率。氢同位素分馏因子（α D石膏-水）在3 ℃和55 ℃之间每℃增加0.0001单位，
Gypsum (CaSO4 center dot 2H(2)O) is a hydrated mineral containing crystallization water, also known as gypsum hydration water (GHW). We determined isotope fractionation factors (alpha O-17, alpha O-18 and alpha D) between GHW and free water of the mother solution in the temperature range from 3 degrees C to 55 degrees C at different salinities and precipitation rates. The hydrogen isotope fractionation factor (alpha Dgypsum-water) increases by 0.0001 units per degrees C between 3 degrees C and 55 degrees C and salinities
