根据在法国汪戴省莫湼南賽弗尔河流域的侵入花崗岩岩基所取得的样品,对于鈾在花崗岩里分布的情况作了系統的研究,样品是在以間距为500米勘探网度内的浅鑽孔里取样。根据化学分析的結果,說明含有很多常見的岩石化学成分(SiO_2,Al_2O_3,Fe_2O_3,FeO,MgO,CaO,Na_2O,K_2O,TiO,P_2O_5,H_2O),另根据光譜分析,查明含有鎢。鈾元素是利用螢光法测定的,同时固定的和游离的鈾两者间的区別也巳經分別确定。区域放射性测量,在野外是利用盖革計数器,在实验室里是利用核子感光板計算α—射线跡点数。在研究区里水的含氡量是利用閃爍計数器测定的。在岩体的剖面上进行了岩石学的研究,对于鈾的分布状况的鑑定,則是利用放射性照相方法。根据許多結果得出等值线,直角和三角形等图来。对统計数字进行了研究,由此有了可能去确定主要元素——鈾和岩石主要成分之間的关系。因之,就有了可能去查明鈾在分布上的改变是因次生变化而引起的。此外,对于近代的鈣铀云母和若干铀矿床的成因提出一些假說。
Based on the samples obtained from the invaded granite bedrock in the Mönnean Sever River area, Wang Dai Province, France, the distribution of uranium in granite was studied systematically. Samples were collected at an interval of 500 m Shallow hole in the sample. According to the results of chemical analysis, it contains many common petrochemical components (SiO 2, Al 2 O 3, Fe 2 O 3, FeO, MgO, CaO, Na 2 O, K 2 O, TiO 2, P 2 O 5, H 2 O). Uranium is measured by fluorescence, and the distinction between fixed and free uranium has also been separately determined. Regional radioactivity measurement, in the field is the use of Geiger counter, in the laboratory is the use of nuclear plate calculation of alpha ray trace points. Water content in the study area was measured using a scintillation counter. Petrological research has been conducted on the profile of the rock mass. For the identification of uranium distribution, radiographic methods are used. According to many results come contour, right angle and triangle figure. A study of the statistics has made it possible to determine the relationship between the main element, uranium and the major components of the rock. It is therefore possible to ascertain that the distribution of uranium is caused by secondary changes. In addition, some hypotheses about the genesis of modern calcium-mica mica and several uranium deposits are presented.
