glacial deposits 冰河堆積物。

glacial epoch

This succession was based primarily on a series of deposits and events not directly related to glacial and interglacial periods , rather than on the more usual modern method of studying biological remains found in interglacial beds themselves interstratified within glacial deposits 這一順序主要是根據與冰川期和間冰期沒什么直接關系的一套沉積物或現象而排出的,現代更為通用的方法則是研究發現于間冰期河床的生物化石。

In the older rocks below these glacial deposits are detrital uraninite and pyrite , two minerals considered evidence for very low levels of atmospheric oxygen 這些冰河沉積物下方的較老巖層,是瀝青鈾礦與黃鐵礦碎屑;這兩種礦物被認定為大氣中氧氣極為稀少的證據。

Cold event deposits were developed in the nantuo formation of the lower sinian and should be continental glacial deposits in a low - latitude and low - altitude area 冷事件沉積產物為下震旦統南沱冰磧層,屬低緯度低高程的大陸冰川沉積。
