由半透明金属矿物构成的矿床在金属矿产中占有重要的地位,解决这类矿物中的包裹体测温问题,对于研究该类矿床形成的物理化学条件具有一定意义。当前这类矿物中的包裹体测温工作存在的主要问题是:包裹体在显微热台加温过程中,温度升到200℃左右时,主矿物表面开始出现一层钢灰色膜,使主矿物的透明度迅速降低,包裹体开始变得模糊不清,随着温度的继续升高,其透明度急剧降低,直至包裹体轮廓完全看不清楚,使测温工作无法继续进行,即使变换不同的保护气体,仍不能测定其均一化温度。E.Roedder 1985年在我国长沙中国工业大学讲学时曾指出:对这种现象,用一般方法无法解
Deposits made of semitransparent metal minerals occupy an important position in the metal minerals. Solving the temperature measurement of inclusions in these minerals is of great significance for studying the physicochemical conditions of the deposits. The main problems existing in the current temperature measurement of inclusions in this kind of minerals are as follows: during the heating of the inclusions in the micro-hot stage, a layer of steel gray film begins to appear on the surface of the main mineral when the temperature rises to about 200 ° C., The transparency of minerals decreases rapidly and the inclusions begin to become blurred. As the temperature continues to increase, the transparency of the inclusions sharply decreases until the contour of the inclusions is completely indistinct, so that the temperature measurement can not continue, even if different protection is changed Gas, the homogenization temperature still can not be measured. E.Roedder in 1985, China’s Changsha University of China lectures have pointed out: for this phenomenon, the general method can not be solved
