Clay mineral composition in fluviolacustrine deposits or the Heilu soil in the Sjara-Osso-Gol Group of the lower Mid-late Pleistocene in the Dishao-gouwan profile of Sjara-Osso-Gol River, the Middle and Lower Holocene are dominated by illite, yet it is accompanied with a little quantity of mineral such as Kaoline; and the caly mineral composition, which are dominated by aeolian sands are mainly illite-chlorite, accompanied with a little montorillonite in the Upper and the Lower Chengchuan Group of the Upper...

Clay mineral composition in fluviolacustrine deposits or the Heilu soil in the Sjara-Osso-Gol Group of the lower Mid-late Pleistocene in the Dishao-gouwan profile of Sjara-Osso-Gol River, the Middle and Lower Holocene are dominated by illite, yet it is accompanied with a little quantity of mineral such as Kaoline; and the caly mineral composition, which are dominated by aeolian sands are mainly illite-chlorite, accompanied with a little montorillonite in the Upper and the Lower Chengchuan Group of the Upper Holocene. The clay mineral composition in the Quaternary strata of Reijiagouzuizi , Madaqu and the Northwestern marginal land of Sjara-Osso-Gol River area fundamentally coincide to thp.se in Dishaogouwan profile of Sjara-Osso-Gol River. This shows that the Quaternary aeolian sand and loess in the study area deposited under a relative dry and. cold climate condition, but the fluviolacus strine facies or limnetic facies and paleosoil formed under the relative warm wet climatic condition. Therefore, the Late Pleistocene Malan loess or aeolian sands can be a comparison with the fluviolacustrine-deposits under Malan loess and aeolian sands of Chengchuan Group and Sjara-Osso Gol Group.

萨拉乌苏河嘀哨沟湾剖面中晚更新统下部萨拉乌苏组,晚更新统上部的城川组中部,全新统中下部河湖沉积或黑垆土中的粘土矿物组合以伊利石为主,但伴有少量的高岭石类矿物;而晚更新统上部的城川组上下部,全新统上部嘀哨沟湾组以风成沙为主的粘土矿物组合均以伊利石—绿泥石为主,并有少量的蒙脱石。萨拉乌苏河雷家咀子、马达渠以北西北部梁地的第四纪地层中的粘土矿物组合与萨拉乌苏河嘀哨沟湾剖面的结果基本吻合。这表明本区第四纪风成沙与黄土是在相对干冷气候下沉积的,而河湖相、湖沼相及古土壤是在相对暖湿的气候下形成的。 由本区第四纪地层中的粘土矿物组合,反映自晚更新世以来,本区气候曾经历暖湿→干冷→温湿→干冷→暖湿→干冷的多次更替,大体与北半球的玉木——里斯间冰期、前玉木冰期、玉木间冰阶、玉木主冰期、冰后转暖期和新冰期气候变化趋势一致。

The Malan Loess, the Chengchuan Formation and the Salawusu Formation in the Salawusu River area on the Ordos plateau are sediments of different stages and facies, with the first two over lying the last one. The Malan Loess and the Chengchuan Formation are found to be sediments of loessic and sand facies deposited in one and the same stage under wind action. In terms of stratigraphic association, the late Pleistocene in the Salawusu River area corresponds to that in the adjoining depression-valley and desert-loess...

The Malan Loess, the Chengchuan Formation and the Salawusu Formation in the Salawusu River area on the Ordos plateau are sediments of different stages and facies, with the first two over lying the last one. The Malan Loess and the Chengchuan Formation are found to be sediments of loessic and sand facies deposited in one and the same stage under wind action. In terms of stratigraphic association, the late Pleistocene in the Salawusu River area corresponds to that in the adjoining depression-valley and desert-loess areas. The late Pleistocene strata and the proportion of the extinct species of fossil vertebrates in them indicate that the Salawusu Formation is early Late Pleistocene in age, whereas the Malan Loess and the Chengchuan Formation are late Pleistocene.

在鄂尔多斯高原萨拉乌苏河中下游地区,传统认为河湖相沉积的萨拉乌苏组实际上包括了一套以风成沙沉积为主的城川组地层。城川组风成沙与该河上游的马兰黄土是同期风力作用下的沙相和黄土相沉积,两者呈相变关系。而马兰黄土、城川组与真正属于河湖相沉积的萨拉乌苏组地层为上下叠覆的关系。这种地层接触关系,由地层中遗存的脊椎动物化石绝灭种比例的差别得到佐证。本区萨拉乌苏组地层形成于晚更新世前期,马兰黄土、城川组形成于晚更新世后期。

According to the analyses and studies of the grain-size, sporopollen , vertebrate fossils and stratum sedimentary facies in the upper pleistocene strata of the Salawusu River area, this paper discusses the palaeogeographic environment and its evolution during the late pleistocene.1. The palaeogeographic environment of the fluviolacustrine facies strata of the Salawusu Formation formed in the early stage of the upper pleistocene is warm-hummid forest steppe.2.

According to the analyses and studies of the grain-size, sporopollen , vertebrate fossils and stratum sedimentary facies in the upper pleistocene strata of the Salawusu River area, this paper discusses the palaeogeographic environment and its evolution during the late pleistocene.1. The palaeogeographic environment of the fluviolacustrine facies strata of the Salawusu Formation formed in the early stage of the upper pleistocene is warm-hummid forest steppe.2. In the late stage of the late pleistocene, the Chengchuan Formation which mainly consists of aeolian sandy deposits chiefly forms under dry-cold desert, desert steppe and in the meantime, it underwent a series of alternating evolution processes of temperate-cool's shrub steppe,sparse woods steppe and forest steppe with this environment.3. The Malan loess in the area has the same geological age as that of dry cold desert steppe.4. The Salawusu Formation is assigned to the Riss/Wurm intcrglacial age, dating back to 1.1×105-7×104 yrs B.P.,thereas the Chengchuan Formation andthe Malan loess are in the Wurm glacial age with an assumed date of 7 × 104 - 1 ×104 yrs B.P..

对萨拉乌苏河地区上更新统地层作进一步划分的基础上,本文论述本区晚更新世前期萨拉乌苏组沉积时的古地理环境为暖湿的森林草原。后期城川组主要形成于干冷的荒漠草原—荒漠环境,期间经历了一系列温凉湿润的灌丛草原—疏林草原、森林草原等环境的交替演化过程。
