摘要
根据《海洋四号》861—881航次获得的岩心资料,通过对沉积物类型的观察,对其中的几种自生矿物钙十字沸石、蒙脱石、重晶石、微结核、非晶质SiO_2等矿物的成因和与沉积物类型的相关性进行了探讨。
According to the sediment types of core obtained from Legs 861-881 of the 'HY 4', the paper discussed the relationship between the formations of some authigenic minerals (phillipsite, montmorillonite, barite, micronodules, non-crystalline SiO2) and sediment types.
Phillipsite and montmorillonite have been formed from volcanic materials by seawater solution, so these minerals have a close relation with palagic clay.
Micronodules widely spread in the surface sediments. The author considers them as one of the authigenic ferromanganese minerals and barite as authigenic mineral. Its formation is related to siliceous bioclasts.
