The Application Of Geochemical Exploration Methods In The Concealed Fault Focus On "Milintibet Area"

The working location is in the south Tibetan region. The tectonic is between India plate andEurasian plate joints. It has fracture development, strong activity. The frequent seismic activitiesand earthquake magnitude is high. Because the fracture is development, the rise of an increasinglylarge engineering areas (railways, roads, utilities, airports, etc.) caused by the construction andplanning constraints.Because the working location is in the vegetation growth,, quaternary cover, deep bedrockoutcrops is very poor, the surface geological investigation is very difficult. Therefore, many faultsare buried fault. Practice has proved. Geochemical methods is one of the most effective ways todetect concealed faults. Geochemical exploration methods (i.e., to enrage measurement) is a newway to find concealed fault, in the early1980s, it is put forward by the Swedish scholars.Geochemical exploration methods (i.e., to enrage measurement) is introduced into our countrysince the late1980s. It has been used by Chengdu university, such as domestic research andapplication of several units. This method technology has become mature, and has reached theinternational advanced level. After years of research, we has confirmed that the interior of theearth has a vertical rising air flow. This air flow in the process of migration towards the surface,will carry on the migration path in submicron to exists in the form of nanoparticles size solidparticles, forming contain a variety of elements (up to about40kinds) of airflow to enrage. Abovethe fault, the content of elements will be more than that of other regions. The content of manyelements is obvious ly higher than that in the background, which appears as a point. In this study, ithas been confirmed that Pb, Zr, U and other rare elements will be abnormal. Using highlysensitive analysis detector, the abnormal value can be identified and extracted. So, through anextract of the elements on the measuring point, and analysis of the foregoing elements including10-9～10-12content level. Extract multielement outliers from this point, we can provide thebasis for concealed fault location. Because of the collections in the field are all enrag ing from theinterior of the earth, it reflects the point information bellow, therefore the surface covering is avery small effects on wide-spaced sampling measurement elements.Previous data suggest that the presence of Millington area greater impact on the project,breaking several controversial, Mainly grounded when Jiedidangga fault, Lilong fault, Lmalingfault, Nyang fault Mizoguchi than small fracture and so on. Through the above lots Quaternarycover may break through the implementation of geochemical exploration. Combined with existinggeochemical exploration, including geological, seismic, geothermal, mountain engineering achievements. Its comprehensive analys is to determine the presence or absence of these fracture.Either that earthquake safety evaluation, regional tectonic stability evaluation provide basicinformation, but also provide for the production units. Therefore, the study of this article hasimportant theoretical and practical significance.By radon and gas anomalies to peak distribution, combined with surface geological surveys,seismic, fracture, Mountain project expose this result. It initially considered that determines theJiedidangga fault the presence and distribution. Jiedidangga fault goes through the Gege spagroove, viewing platform and Yusong village. Lane dragon fault spread roughly Lane dragonValley. Lama fracture exists only zangbajuezhu fault southwest direction of Homes on theMountain. Lane dragon fault not exist zarao rural area. The so-called Niyang fault does notexist.The bangnacun does not exist. The Brahmaputra of zaxirao on the left bank floodplain Notdevelop fault distribution. It’s the right bank of the river floodplain may exist modest buried fault.There is no breakage in biding of Mizoguchi.
