摘要
本文主要讨论应用X射线荧光方法测定金的共生元素砷,从而圈定金矿体并推算金品位的前提、方法和地质效果。本方法在现场直接测定,快速、成本低,具有很好的地质效果和经济效益。
The paragenetic relations of gold with As, Ba, Cu, Hg, Mo, Sb is often found in gold mines, therefore the distribution
and content of these elements in ore bodies can be used to indicate the location of gold mines and delineate the ranes of
gold mines. Radioisotope X-ray fluorescence analysis, which can rapidly make on-the-spot determination of the contents
of As, Ba, Cu, Sb, provides a effective method for gold mine exploration.
This paper, taking the gold mine in Xinjiang as an example, illustrates the method of delineating gold ores and evalu-
ating gold ore grade according to the studies of paragenetic element relations. It shows that the method has an unique
merit in speeding gold mine exploration and improving economic efficifency.
