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