摘　　要：本文介绍了应用联合剖面和电测深方法在南平市延平区洋后地区矿泉水勘查中推测可能含水断裂构造的具体应用。工区位于福建省西北部洋后镇境内,据野外踏勘部分泉水点水质质量基本达到饮用矿泉水标准,区内断裂构造较为发育(F1~F4,其中F_(4)为遥感解译断层),断裂(构造)、基岩裂隙富水性较好,具备寻找优质天然饮用矿泉水的巨大潜力。为改善当地居民用水条件,振兴乡村经济,在工区开展了包括物探勘查在内的饮用天然矿泉水调查评价工作。基于工区地质环境背景与水文地质条件,在重点区域开展了3条联合剖面(L_(1)、L_(2)、L_(3))测量进行断裂构造的快速识别,继而对联合剖面重点异常位置布设2条电测深剖面以进行异常验证与综合研究。根据综合电法的异常特征,推测了2条北西向断裂构造F_(5)、F_(6),为下一步钻探工作提供了具体方向。研究结果表明:联合剖面结合测深在南平市延平区洋后地区矿泉水勘查中可以有效减少单一物探方法的多解性和误判性,有利于提高对断裂构造识别的精准性。This paper introduces the specific application of joint profile methods and electrical bathymetry methods to speculate possible water-bearing fault structures in mineral water exploration in Yanghou area,Yanping District,Nanping City.The work area is located inYanghou Town,northwest Fujian Province,according to the field exploration of some spring water points water quality basically meet the drinking mineral water standards,the fault structure in the area is relatively developed(F_(1)~F_(4),of which F_(4)is remote sensing interpretation fault),fault(structure),bedrock fracture water richness is good,with great potential to find high-quality natural drinking mineral water.In order to improve the water conditions of local residents and revitalize the rural economy,the investigation and evaluation of drinking natural mineral water,including geophysical exploration,was carried out in the work area.Based on the geological environment background and hydro-geological conditions of the work area,three joint profiles(L_(1),L_(2),L_(3))were measured in key areas to quickly identify fault structures,and then two electric bathymetric profiles were arranged for anomaly verification and comprehensive research at the key anomalies of the joint profile.According to the anomalous characteristics of the comprehensive electrical method,two north-west fault structures F5 and F6 were speculated,which provided specific directions for the next drilling work.The results show that the combined section combined with bathymetry can effectively reduce the multi-solution and misjudgment of a single geophysical method in mineral water exploration in the post-ocean area of Yanping District,Nanping City,and is conducive to improving the accuracy of fault structure identification.
