接触交代型铁矿床中,钠长石化与铁矿化之间的密切关系,很早就为我国地质工作者所注意。近年来,许多地区的地质报告都描述得十分详细,积累了大量可贵的资料。 在实验研究方面,无论是在熔融状况下,还是在水热条件下,用NaCl萃取岩石中铁的研究,都已得到令人信服的结果。E.奥尔索斯(E.Althaus)等(1969)在350—500℃条件下,用0.1—2N NaCl溶液与海绿石、伊利石、蒙脱石、白云母等矿物发生反应,反应后溶
In the contact metasomatism iron deposits, the close relationship between albite and iron mineralization has long been paid attention to by our country’s geologists. In recent years, geological reports in many areas have been described in great detail and have accumulated a great deal of valuable information. In experimental studies, convincing results have been obtained from the study of the extraction of iron from rock with NaCl, both in the molten state and under hydrothermal conditions. E. Althaus et al. (1969) reacted with minerals such as glauconite, illite, montmorillonite and muscovite using 0.1-2N NaCl solution at 350-500 ℃. After reaction Soluble
