| 摘 要： | 罗圈组作为冰川沉积物,已为地学界所重视。作者从地层层序、粒组分析和沉积环境等沉积学角度分析,初步认为它不管是冰川沉积物或是冰川—重力流改造沉积物,均应属水下岸坡冲积扇的沉积物。

| Abstract: | As a glacial deposit, the Luoquan Formation has been paid more attention to by the geonony circles. By means of the sedimentary strata sequences and through analyzing the grain grade and the sedimentary environment,the authors preliminarily consider that whether it is a glacial deposit or the products of the glaciation-gravity flow reconstruction, it must be the alluvial fan of the off-shore slope. |
