【摘要】 陕西户县太平麦饭石主要是一种钙碱性的中酸性岩浆岩晚期的产物,主要岩性为花岗质浅色岩类,呈斑状或似斑状结构。矿石主要矿物成分为斜长石、钾长石、石英、黑云母,以及磁铁矿、高岭石等,SiO2、Al2O3、K2O的平均含量分别为59.22%、18.48%、9.33%,稀土分布曲线呈较平缓的向右倾斜型,含有几十种对人体有益微量元素,且有毒元素含量低,麦饭石溶出液含量达国家引用矿泉水标准,对水中重金属有较强的吸附作用。更多还原

【Abstract】 Taiping Maifan stone in Hu county,Shanxi,is later products of calcium and alkalescent,middling acidity magmatic rock . Taiping Maifan stone′s character is of light and granite texture rock .The ore has porphyritic texture and block structure.The main mineral component of the ore: plagioclase,feldspar of potassium,quartz, biotite,and magnetite,kaolinite etc,the average content of silicon dioxide alumina alkali feldspar distinguishes to 62.22%,18.48%,6.33%,and the distribution curve of rare earth presents more than tilt rightwards slowly. The ore has beneficial trace element of the human body,and the poisonous content of element is low.The content of Maifan stone liquid reach the national mineral aqua standard,having strong absorption of heavy metals in aqua.更多还原
