The geographic distribution of regional soils such as loess soil, lateritesoil andexpansive soil in China and their special engineering properties are briefly described in this paper.
Laterite ores can be approximately divided into two categories: the limonite and the humus soil.
红土镍矿大致可分为褐铁矿型和腐植土型两类。

It is typical strong structural soil with higher structural strength result from agglutination, and its pedogenic evolutionary process is similar to that of laterite.
