根据盐湖野外考察和钻井记录,盐湖沉积的重要特征是盐类沉积物和碎屑沉积物互层或混层,构成沉积旋回。盐湖碎屑沉积物一般是松散的,或致密的,与石膏和其它盐类,特别是碳酸盐密切共生,多具微层理。我们曾先后对青海、内蒙等地区某些盐湖163个沉积物样品中不溶物进行了粒度分析。本文报导的是对这些盐湖沉积物粒度成分研究的初步结果。所有原始样品均是找室历来野外考察中采取的。由于盐湖碎屑沉积物中常常含有不同量的可溶的、或不溶的其它盐类沉积物,情况比较复杂,以及作者水平有限,本文不妥之处欢迎指正。 According to the field investigation and drilling records in the Salt Lake, an important feature of the salt lake sediments is that salt sediments and clastic sediments are interbedded or mixed to form sedimentary cycles. Salt lake clastic sediments are generally loose or dense and closely intergrowth with gypsum and other salts, especially carbonates, with many microtitrains. We have on the Qinghai, Inner Mongolia and other areas of some salt lake 163 sediment samples were analyzed for particle size. This article reports the preliminary results of the study on the particle size composition of these salt lake sediments. All the original samples were taken from the field investigation. As the salt lake sediments often contain different amounts of soluble or insoluble salt sediments, the situation is more complicated, and the authors are limited, the article welcomes the correction of the wrong place.
