山东境内至今已发现几十处麦饭石矿 ,其中以“泰山麦饭石”、“雪花山麦饭石”和“青岛麦饭石”较为典型。三者均为风化—半风化状的中酸性岩浆岩 ,其化学组分与国内、日本的典型麦饭石矿床基本一致 ,主要物化性能为溶出性、吸附性、双向调节性、生物活性效应和复用性等。 Up to now, there have been dozens of Maifan quarries in Shandong Province, of which “Taishan Maifan Stone”, “Snow Mountain Maifan Stone” and “Qingdao Maifan Stone” are typical. All of them are weathered-semi-weathered magmatic rocks, and their chemical compositions are basically consistent with the typical maifanite deposits in China and Japan. The main physicochemical properties are dissolution, adsorption, bi-directional regulation, bioactivity and Reusability and so on.
