///This
    paper was based on the field investigation of the typical geological sections
    and multiple methods of laboratory tests on the samples from the slopes along
    the Baoshan-Tengchong highway and adjacent area in Yunnan Province. It
    discovered a swelling clayey diatomite in the Neogene lacustrine strata, named
    Mangbang formation, at Tengchong area Yunnan Province. The discovery of the
    swelling clayey diatomite in Mangbang Basin, as well as the researches on its
    engineering properties, is not only instructive for realization of the
    mechanism of related geo-hazards along the Baoshan-Tengchong high way, but also
    helpful to understanding the engineering properties of some lacustrine deposits
    and their easily causing geohazards in southwestern China.
