庙下饮用天然矿泉水位于九岭隆起带南缘,区内发育有北西向断裂(F1)与北东向断裂(F2),泉点主要受 F1 断裂控制.调查区岩浆岩为晋宁期中细粒黑云母英云闪长岩.通过对区内出露的泉点进行丰水期、枯水期水质分析,偏硅酸含量 41.36mg/L～45.77mg/L,属偏硅酸矿泉水.经初步估算调查区允许开采量为 5.55m3/d,预测补给量为 235.20m3/d.综合区域地质背景、矿区、特征及水质特征等,初步分析了庙下饮用天然矿泉水特征与成因分析.
Analysis on the Characteristics and Causes of Drinking Natural Mineral Water in Miaoxia,Jiangxi Province
Miaoxia drinking natural mineral water is located at the southern edge of the Jiuling Uplift,with northwest trending faults(F1)and northeast trending faults(F2)developed in the area.The spring point is mainly controlled by the F1 fault.The surveyed igneous rocks are fine-grained biotite quartzite diorite from the Jinning period.By analyzing the water quality of the exposed spring points in the area during the high and low water periods,the content of meta-silicic acid is 41.36mg/L-45.77 mg/L,which belongs to metasilicic acid mineral water.According to the preliminary estimation,the allowable mining output in the survey area is 5.55m3/d,and the predicted replenishment is 235.20m3/d.Based on the comprehensive analysis of regional geological background,mining area,characteristics,and water quality characteristics,the characteristics and genesis of natural mineral water for drinking in Miaoxia were preliminarily ana-lyzed.
