Based on investigation of the moraine and outwash deposits in above regions, the authors find that they are very complicated Quaternary deposits with special composition, structure and properties. Their engineering properties are mainly related with the composition of the gravel and the filled material.
通过对上述地区大量冰碛物和冰水沉积物的现场调查发现,冰碛物和冰水沉积物是一类成分、结构和性质都十分复杂的第四纪堆积物,其工程性质主要与母岩成分和充填胶结物的矿物成分密切相关。

The paleolatitude of the Nantuo sandstone of lower sinian in the Earstern Gorge Region of the Yangtze River was determined to be 74.5°-72.1°, and that of the Nantuo tillite was 86°.
用古地磁学方法测定长江峡东地区下震旦系南沱砂岩的古纬度是74.5°—72.1°,南沱冰碛岩的古纬度是86°。

Some metallic ores are found in the margins of batholiths and other intrusives which can be detailed under drift by magnetic surveys.
有些金属矿是在岩盘与其它侵入体的边缘找到的,而磁力测量能够确定这些冰碛层覆盖之下的岩盘和侵入体。
-
The former were formed by the long-timed and repeating contact of till gravel with the ice-bed, which produced the maximum shear in the certain depth of layer under the surface and brough about the cracks of static fatigue and contact fatigue.
平行裂隙的成因是冰碛石长期和反复与冰床接触,在冰床表层以下一定深度产生最大剪应力,沿平行冰岩界面使岩石出现静疲劳和接触疲劳破裂。
-
Among such features may be synclines and anticlines, geological faults , salt domes, undulations of the crystalline bedrock under a cover of moraine, ore bodies, clay deposits and so on.
例如向斜、背斜、断层、盐丘,冰碛层之下结晶岩的顶面起伏形态,矿体以及粘土矿床等。

flysch:复理石
像冰碛岩(Tillite)、风暴岩(Tempestite)、复理石(Flysch)和滑来岩块(Olistolite)这样的成因术语和构造岩相术语,应避免用于正式岩石地层单位名称. 因为这样的术语和处理方法违背研究中的多重假没原则,而且采用成因限制的做法影响了单位概念本身的可信度,
-
medial moraine:中碛
少女峰的东南侧是阿莱奇冰川,贯穿阿莱奇冰川、与少女峰轴心平行的黑色中碛(medial moraine)清晰地将这条冰川标了出来. 这条冰碛由桌面背景图片岩石和土壤碎屑形成,而岩石和土壤岩屑则是由位于少女峰和门希峰峰顶附近的三个高山冰川收集而来--在这些流动的冰块混合形成阿莱奇冰川时,
-
striation:擦痕
因冰河流向固定,冰床下的底岩或挟运的冰碛石上,常因磨蚀留下与冰河流向一致的擦痕(striation). 山地冰河於冰河谷头,侵蚀形成半圆形的冰斗(cirque);而在冰河谷侵蚀形成U字形的冰河槽(glacial trough);当两冰斗靠连时,

Panthera uncia:雪豹
适应高山生活的食肉兽雪豹(Panthera uncia),是中亚高山的特有种,可活动至雪线. 鸟类稀少,西藏雪鸡(Tetraogallus tibetanus)和褐岩鹨(Prunella fulvescens)于夏季可分布至海拔6000米左右地区,栖息于向阳的冰川与冰碛堤间的小片草地上,
