摘要
对南京二叠系栖霞阶灰岩中的矿物学研究表明,该燧石的碱活性不仅取决于α石英的晶体结构,而且还与燧石的矿物集合体构造有关。这种燧石非活性特征是由于其含有沥青质之故,沥青质的存在抑制了碱-集料反应的进行。
Mineralogy research about Qixia chert indicates that the alkali reactivity of chert is related not only to the crystal structure of α-quartz but also to the construction of its mineral assemblage. The non-reactive feature of Qixia chert result from its asphalt content, which restrictes the alkali-aggregate reaction.
