| 摘 要： | 鲁西南平原区第四纪全新世地层自下而上划分为5个组：下部为黑土湖组，中部为同期异相的巨野组、单县组、鱼台组，上部为黄河组。熏土湖组为全新世早-中期湖沼相沉积的灰-灰黑色粘土类粉砂质粘土，含大量淡水螺蚌介壳；巨野组为全新世黄河早期沉积，由褐黄色粉砂夹棕红色粘土组成；单县组为黄河古决口扇、古河道沉积，岩性主要为细砂、粉砂；鱼台组为黄河古决口扇前缘洼地沉积，岩性为-套棕红色粘土，局部夹粉砂土。黄河组为黄河现代河床及河漫滩沉积，由灰黄色粉砂土、粘质砂土夹粘土层及砂土组成。 |

| Abstract: | Holocene strata in Quaternary in southwest plain area can be divided into 5 formations from lower to upper part; Heituhu formation is its lower part, Juye formation, Shanxian formation and Yutai formation with synchronous heteropic facies are its middle parts, and Huanghe formation locates in its upper part. Heituhu formation is gray and gray--black silty clay with limnological facies in early and middle period of Holocene, and bearing lots of spiral case;Juye formation is sedimentary of early Huanghe formation in Holocene, which is composed of brown--yellow silt, accompanying with brown--red clay; Shanxian formation is old crevasse splay and old channel sedimentary of the Yellow river, and its propery is mainly fine silt and silt; Yutai formation is frontal depression sedimentary of Yellow river old crevasse splay, and its property is brown--red clay, accompanying with silt. Huanghe formation is recent river bed and alluvial flat sedimentary, which is composed of gray--yellow silt, silty clay and clay. |
| Keywords: | Juye formation Shanxian formation Yutai formation Holocene strata plain areas in southwest Shandong province |
