都山天然矿泉水赋存条件及形成机理研究
|
摘要
从区域地质背景、水文地质条件、水化学特征等出发,对秦皇岛都山Sr型矿泉水的赋存条件和形成原因进行了分析,认为该矿泉水形成和赋存于花岗岩与三屯营组片麻岩接触带部位,泉水附近有挤压带、断裂带数条,为地下水提供了贮存空间和运移通道,F2正断层是控制矿泉水的主要构造带,控制着矿泉水的富水性;都山岩体中的中心相黑云母花岗岩和过渡边缘相斑状花岗岩中存在大量的斜长岩和钾长石,大气降水渗入地下后,通过裂隙向下运移,与长石类矿物作用,长石解体,Sr又极易与钙产生类质同象置换现象进入含钙矿物中。水中Sr通过岩石中Sr元素的溶滤作用产出,随着溶滤时间增加,锶在水中不断富集,最终达到标准而形成含锶型矿泉水。
Based on geological background, hydrogeologic conditions and hydrogeochemical characteristics,occurrence conditions and formation mechanism of strontium type mineral water in Dushan was studied, and thinks that mineral water formed and occurrence in the contact zone of granite and gneiss. There are squeeze zones and fault zones near the spring water, which provide storage space and transportation channels for groundwater. The F2 fault is the main tectonic zone that controls mineral water and controls the water abundance of mineral water.There are many plagioclase and potassium feldspar in the central black mica granite and transitional marginal facular granite in the Dushan rock mass. After atmospheric precipitation seeps into the ground, it moves downward through the cracks, and acts with feldspar minerals. Sr is also very easy to replace with calcium to produce a similar phenomenon into calcium-containing minerals. In water, Sr is produced by the dissolution of Sr elements in the rock. With the increase of dissolution time, strontium is continuously enriched in the water, and finally the standard is reached to form strontium containing mineral water.
