四川饮用天然矿泉水的基本特征

ESSENTIAL FEATURES OF DRINKING NATURAL MINERAL WATER IN SICHUAN

四川矿泉水在川西地区主要分布在盆周山区，且多集中在前龙门山，在川东地区则主要分布于川东褶皱束。矿泉水受构造断裂、活动断裂构造蚀变带及褶皱控制明显，或沿深大断裂深部循环，或沿褶皱层间裂隙、构造裂隙向倾伏方向富集、运移、承压出露。矿泉水类型较为单一，以锶、偏硅酸及其复合型为主，多为淡矿泉水，应注意寻找锌、硒、碘等稀有类型的矿泉水。

Most of the drinking natural mineral springs in west Sichuan outcrop in the margin of Sichuan Basin, especially. in the front Longmen Mountains and those in east Sichuan emerge out from the east Sichuan bundle of fold. The natural mineral springs are obviously controlled by fault, fold and structural alteration zone and the water circulates along deep fracture zone and moves along interlayer faults or tectonic fissures, finally, wells out under an artesian condition. The natural mineral water is characterized by monotonous types, i. e. Sr-bearing mineral water, metasilicate mineral water or their combination are dominant. They are fresh mineral water. Consequently to search for rare mineral water with Zn, Se, I shall be paid attention.
