    摘要:

    内容提要:通过溯源追踪分析方法对研究区内不同地层锶元素丰度、主要岩土体矿物组成及含锶矿物进行分析,探究流域水体中锶元素的形成原因。分析发现,研究区内板岩类、长石石英砂岩等岩层及第四系残坡积碎石土等锶元素含量相对于区域表现为高、较低、较高等特征;板岩类、碎石土等岩土体中粘土矿物含量较高,而蒙脱石、伊利石是构成粘土矿物的主要成分,其中与锶性质接近的元素被锶替代、置换,形成了含锶较高的矿物,从而为区内地下水中锶含量较高奠定了物质基础。降水入渗到地表岩土体的裂隙、孔隙中,与周围岩土体中的各类矿物、二氧化碳及水体进行淋滤、溶解、离子交换等反应,水体中溶入的主要阴、阳离子为HCO- 3、Ca2+Mg2+等;区内岩层中锶含量总体较高,溶入水中的Sr2+较多,达到锶型饮用天然矿泉水标准,最终形成了水化学类型为碳酸氢钙镁型的锶矿泉水。本文对水源区岩土体矿物成分分析、矿物结构、离子交换和运移的研究方法,对各类矿泉水勘查和形成机理分析有重要的借鉴意义。

    Abstract:

    Objectives: Analysis of the abundance characteristics of strontium elements in study area, the mineral composition of the rocks within the strata identified, and analyzed the chemical structure of the main minerals rich in strontium elements in the minerals. The water seepage into the rock and soil fissures, aqueous rock reactions with strontium-rich minerals. Then, strontium mineral water formed when more strontium elements are dissolve into the water. Methods: Adopting the analysis method of traceability, regional comparative analysis of the abundance characteristics of strontium elements in various strata of rock and soil bodies in the study area, and analysis of strontium-containing minerals within the main rocks. based on the structure of the main strontium-rich minerals, strontium ions therein dissolve into the water by way of substitution with ions similar in nature, and the determination of Sr2+ reaches the strontium-type natural mineral water standard for drinking purposes. Results: The strontium content in the main strata that in the slate, feldspar quartz sandstone and Quaternary residual slope gravel soil in the study area is high, low, high, etc. relative to the region. The slate has a high clay mineral content, and the main components of clay minerals are montmorillonite and illite, which have high strontium content. The structure of montmorillonite makes it easy for strontium in it to replace and displace with elements of similar nature, and dissolve into the water, forming a water supply with high strontium content. Conclusions: Precipitation infiltrates the surface into the fissures and pores of strontium mineral-rich rock and soil bodies. Minerals undergo aqueous rock reactions such as leaching, dissolution, and ion exchange with carbon dioxide and water. The main anions and cations dissolved in the water are HCO- 3, Ca2+ and Mg2+. The strontium content in the rock formation is generally higher, and more Sr2+ is dissolving into the water, which can reach the standard of strontium-type natural mineral water for drinking. This results in strontium mineral water with a water chemistry type of calcium magnesium bicarbonate.
