顺平县地层中白色固体及红色液体物质的分析

Analysis of White Solid and Red Liquid in Stratum of Shunping County

目的对河北省顺平县李司庄村在钻井过程中于地下117.3 m深处发现的“白肉”样物质和酷似“血水”的红色液体进行分析,探讨其对人体及地下水质的影响。方法将“白肉”样品进行X-射线分析和红外光谱分析,用透射电镜观察并测定其成分和结构;因未采集到“血水”,所以对地下水进行了水质分析。结果“白肉”是粘土类矿物——坡缕石(MgAlSi4OH·4H2O);地下水为重碳酸钙镁型地下水,“血水”可能是地下水溶解岩层中的铁,富含Fe2O3而呈红色。结论坡缕石食用后易形成肠道阻塞,对人体有害,该地区地下水可以饮用。

Objective To analyze the fat-like material and blood-like red liquid found in stratum with a depth of 117.3 m during the process of drilling in Lisizhung village, Slumping county, Hebei. Methods The fat-like material was analyzed by X-ray diffraction infrared spectrum and eletronic microscope. Because the blood-like ground water wasn't collected, so the normal ground water quality was analyzed. Results The fat-like material was palyqorskite, one kind of clay mineral(MgAlSi4OH·4H2O). Ground water was calcium-magnesium bicarbonate type. The formation of blood-like ground water might be caused by the excessive ferric oxide dissolved from the stratum to the ground water which revealed red color ground water. Conclusion Ingestion of palyqorskite as food was easy to cause intestinal obstruction. The ground water in this area cound be used as drinking water.
