The island was formed by debris and erosion at the end of the last glacial period . 45. At the end of the last glacial period the continental glaciers were melting to the north. 46. The impact of earlier karstification ( solutional erosion ) has been eliminated by the last glacial period . 47. He noted a correlation of a wet period in the Levant with a glacial period in Europe. 48. This limited glacial erosion also means that V�g?had limited glacier erosion during the last glacial period . 49.
