| Abstract: | The
kaolinite tonstein in the seam 5# is formed by acidic ash alterated in the acid
medium in peat bog in tongchuan district.In the course of alteration,the unstable elements
in supergene zone are leached out in quantity,but the stable ones are relatively
enriched.The original matter of the tonstein and its grain size are main reason for that
the different textures of the tonstein are of different element contents in the same bed. |
