A Certain Basin Uranium Exploration In Gamma Ray Logging Technology

With the rapid development of current world economy and society,the traditionalthe traditional energy coal,oil,natural gas,has been far from satisfying the needs ofeconomic development and environmental protection is an urgent need to find newefficient and clean energy alternative.Uranium is a rare radioactive metallic elementand a extremely singificant strategic resource that its nuclear fission can produceenormous energy,which accounts for two of one million in the crust averagely,and theprobability of its formation of the available industrial deposit is relatively rare.Naturaluranium is the raw meterial to produce nuclear weapons,nuclear submarines andnuclear power plants power required for basic raw materials,therefore uraniumresources is an extremely important and sensitive strategic resources and energy、mineral,which has a dual role in national defense and national economic construction.A certain basin locates in the Xi Ge Ze area and Na Mu Ling County.Theposition of tectonic basin is in the Gang Wa Na northern margin of the Te Ti Sitectonic domain,between the Ban Gong-Nujiang suture zone and the junction of YaLu Zang Bu River,which locates precisely at the Late Paleozoic Gang Wa NaNorthern margin-Mesozoic the Gang Di Si-Xi Ma La Ya tectonic District Long GeEr-the Gong Bu Jiang Da up-faulted zone and Gang Di Si-Xia Ca Yu Wan YanMountain-Xi Ma La Ya magmatic arc with binding site.Basin basement is set in thescidic volcanic rock,intrusive rocks,uranium high abundance,is the major source areasin the basin. The pre-check for the Gang Di Si Volcanic-magmatic arc rift basins in the basinsurrounding a wide range of acidic rocks exposed Cenozoic.Based on the results ofthe word of the uranium geology in the basin in this year and before,Nei Ga ZhaTeam,Zong Dang Team is defined as a cap rock of the basin and its underlying stratais defined as the basin basement.The word about the geological conditions in A certain basin north edge aroundthe sndstone-type uranium mineralization and leachable sandstone-type uraniumgeological,takes into account other types of mineralization.The preliminary word of acertain preliminary reconnaissance of the basin completed a survey ofgeological,geophysical and other routes.From the prelininary data of the basicanalysis we have got samples of uranium,thorium and potassium.Troughly roughlyexploring the basi,the preliminary view of the basin has sandstone-type uraniummineralization conditions,to further define the unconformity boundary delineation ofthe main range of the Cenozoic basin cap,determine to find the uranium target layersand to determine the sepuence,clear seam-containing layer,occurrence and lithology.Outcrop observation and a preliminary understanding of the core catalog,diacovereduranium mineralization can be divided into two kinds of sandstone and volcanictype.Sandstone type mineralization in the north the north east side of the basin,thedelineation of the two containing the seam bit.Through the route geological surveyand drilling to expose,we deepen understanding of the gelolgical characteristics andore-controlling factors of the work area.This thesis is mainly about the word in the northern margin of the certain basin tocontinue exploration around the sandstone-type uranium mineralization in geologicalcondition and the basic condition for word about leachable sandstone-type uraniuminto a sandstone-stype uranium mineralization theory to water prospecting model,6borehole gamma logging work in the northern Gazha area and Mount Wu, a total ofover2000meters of logging data.6drill cores,a total of over2000meters, the FD-3010β-γ catalog to measure the heart of radioactive strength of the rock(ore),dividethe segment of the uranium mineralization and ore block.the simultaneousmeasurement of drill hole deviation and hole diameter,check the quality of the drillingworks,explain the parameters for logging data interpretation. We mainly apply the JBS-1B intelligent logging system produced by Chongqing lnstrument Factory.It isthe relatively advanced logging device;its performance is stable and reliable.Thelogging device;its performance is stable and reliable.The logging system is theextenaive use of LSI interface chip functional module independent deaign thinking tosolve the stability and reliability of data interpretaion and data transmission conditionsthe analysis of data interpretation.In this paper,a borehole measurement data as anexample to explain.
