摘　　要：云南临沧拗水处高岭土矿体呈似层状产出,受晚三叠世中细粒二长花岗岩控制,风化后形成高岭土矿。主矿体长约257m,宽约300m,矿体厚度5.8m~13.31m,平均厚8.82m,矿体厚度稳定程度属稳定,原矿主要化学成分Al_(2)O_(3):15.24%~27.38%,平均19.62%;Fe_(2)O_(3):0.08%~0.80%,平均0.34%;Ti0_(2):0.11%~0.13%,平均0.12%。矿体具垂直分带性,其形态及产状受地形控制,通过内生岩浆作用、表生风化成矿作用及风化壳风化三个重要阶段,形成了风化型高岭土矿床。The Aoshuichu kaolin deposit inLincang,Yunnan,occurs in a stratiform shape controlled by Late Triassic medium-to fine-grained monzogranite.The main ore body is approximately 257m long and 300m wide,with a stable thickness ranging from 5.8m to 13.31m(average 8.82m).The ore contains Al_(2)O_(3)(15.24%-27.38%,avg.19.62%),Fe_(2)O_(3)(0.08%-0.80%,avg.0.34%),and TiO_(2)(0.11%-0.13%,avg.0.12%).The deposit exhibits vertical zoning,whichis influenced by topography.Magmatism,supergene weathering,and weathering crust processes formed the weathering-type kaolin deposit.
