凡口铅锌矿区空气颗粒研究

利用透射电镜镍网对凡口铅锌矿区的空气颗粒进行采集,对所得的颗粒进行透射电镜分析发现,凡口矿区的空气中存在着大量的粒径小于200 nm的颗粒。这些颗粒与工业排放、汽车尾气、建筑尘埃等来源的颗粒在形貌、元素组成上有着很大的不同,推测认为这些颗粒与矿床的存在和开采有着密不可分的联系,初步认为地下矿体的存在会对矿区的空气颗粒种类产生影响。这一联系的发现意味着可通过空气颗粒这种特殊的对象从新的角度对地下的矿体情况进行有效的判别分析。

Study on the Air Particles of Fankou Lead-zinc Deposit

The air particles of Fankou lead-zinc deposit were collected with transmission electron microscopy grids. Through the transmission electron microscopy,it is discovered that there are a large number of air particles with size of less than 200 nm in the air of Fankou lead-zinc deposit. These particles are quite different from industrial emissions,vehicle exhausting,construction dust particles in morphology and elemental composition. So these particles may be inextricably related with the deposits and its exploration. It is primarily considered that the existence of underground ore body will have an impact on the air particles. The discovery means that an effective discriminating analysis can be made to discover the underground ore-bodies in new space from judging the special matters,air particles.
