在过去关于镓在含霞石的岩石中分布情况的文献资料,主要是根据戈尔德施密特和培特尔斯发表的数据。根据他們的资料,在霞石岩中Ga_O_3的含量为0.005％(据八个測定的平均数)。Ga_2O_3∶Al_2O_3=1∶4000。根据哥尔頓和穆拉特的资料,在阿尔坎查斯的霞石正长岩中含Ga 0.002％(据三个測定的平均数)。不久以前,勃里謝諾克报导了苏联各地岩石中镓的分布資料。根据这項资料,在硷性岩(霞石正长岩、正长岩、二长岩和正长辉长岩)中,Ga的含量从0.0018％到0.0070％,平均为0.004％。在这些岩石中Ga/Al·10~(-4)比值从3.0到5.6,平均为4.1。本文乃探討洛沃泽尔岩体(科拉半島)岩石中镓的分布情况。該岩体分布的面积約530平方公里。这个岩体由四个侵入相組成。第一侵入相是具有等粒結构、斑状結构、嵌晶結构以及
The literature on the distribution of gallium in nepheline-bearing rocks in the past is mainly based on data published by Gold Schmidt and Petters. According to their data, the content of Ga_O_3 in nepheline rocks is 0.005% (the average of eight measurements). Ga 2 O 3: Al 2 O 3 = 1: 4000. According to the data of Coulton and Murat, the nepheline syenite in Alcanchas contains Ga 0.002% (average from three determinations). Not long ago, Brichenoch reported on the distribution of gallium in rocks throughout the Soviet Union. According to this data, the content of Ga in the alkaline rocks (nepheline syenite, syenite, monzonite and Zhengchang gabbro) ranges from 0.0018% to 0.0070% with an average of 0.004%. The Ga / Al · 10 ~ (-4) ratio in these rocks ranged from 3.0 to 5.6 with an average of 4.1. This article is to investigate the distribution of gallium in the rock of the Lobozell Rock (Kola Peninsula). The rock mass distribution area of about 530 square kilometers. This rock mass consists of four intruding facies. The first intrusive facies have isogranular structures, macular structures, inlay structures and
