盘山花岗岩裂隙水研究

CREVICE WATER IN THE PANSHAN GRANITE

盘山花岗岩裂隙水起源于大气降水,赋存于各种成因的裂隙中,裂隙水年龄从小于4a到接近40a,差异较大。裂隙水中常量元素和微量元素主要来源于长石类矿物的水解,特别是钙长石的水解,其中SiO_2和Sr在裂隙水中含量较高,已达到饮用矿泉水标准。裂隙水可开采资源量多年平均为1291.56万m^3/a,富水规律明显。

Crevice water in the Panshan granite originates from meteoric water. It occurs in fissures of various origins. The age of crevice water is very different, varying from less than 4 years old to about 40 years old. The common elements and trace elements in crevice water are mainly derived from hydrolysis of feldspars, especially anorthite. The contents of SiO2 and Sr in crevice water are relatively high and have met the standards of drinking mineral water. The amount of minable crevice water resources is 12. 9156 million m3/a on average. The regularity of crevice water yield is clear.
