摘要
在阳山石坳乡黑色石灰土地带的3个剖面采取土壤,进行矿物分析。结果说明这些土壤含有大量轻度接触变质矿物,如硅灰石、透闪石和红柱石(空晶石);还有不少有机粘土矿物复合体,则是轻度变质黑色粘土页岩风化产物,并非由石灰岩风化发育而成。因而不应称之为黑色石灰土,建议暂时称之为黑色土。
he soil (layer A) of 3 profiles in the region with rendizine in Yangshan Shi'ao of Guangdong Province were collected for mineral analysis. The results showed that these soils contained a lot of mineral of lowrank aureole, such wollastorite, tremolite, andalusite, and many organic clay minerals complex. These were the weathering outcomes of lowrank metamorphic black clay shale, not the weathering results of limestone. So this kind of soil shoud be named black soil instead of rendizine.
