摘　　要：在偏光显微镜下,用目前的黏土矿物鉴定方法,难以区分微细粒的沉凝灰岩和泥质岩。为此,提出了一种微细沉积物中黏土的鉴定方法。此方法,在偏光显微镜下能快速、准确地确定有无黏土矿物,区分微细沉凝灰岩和正常沉积的泥质岩,避免微细沉积物(岩)岩性鉴定出错。Under polarization microscope,using existing clay mineral identification method to distinguish bedded tuff and argillaceous rock with grain size less than 0.03 mm is difficult.This paper proposes a method for identification of clay minerals in fine sediments,by which clay minerals occurred in sediment can be rapidly and correctly determined by using polarization microscope,showing the results which is the fine bedded stuff or which is the normally sedimentary argillaceous rock.
