English to Polish Science Geology zlodowacenie

A time interval representing probably hundreds of thousands of years separates these old Ross deposits from New Zealand's late Pleistocene glacial deposits, formed during two glacial stages, the Waimaungan and the Otiran. The Otiran glaciation is probably equivalent in age approximately to the last glaciation of Europe and America (the Würm and the Wisconsin); the Waimaungan glaciation may be equivalent to the Riss and Illinoian.
