Most of them are lakelets of 0.1 to 1.0 ha in area and a mean depth of 0.3 to 1.3 m. They developed mainly after 1961. Studies were made of suspended and dissolved sediment concentration, and the ionic composition of the waters of proglacial streams and lakes, followed by an estimate of the balance of the proglacial transport of material. The calculation showed that the total net deposition of mineral material in the marginal zone amounts to 58.45 t per day. which constitutes 56.07 per cent of the total volume transported by proglacial streams. Borings proved sediments deposited in lakes at present to be of little thickness, ranging from 3 to 19 cm. As to litholology, there in a dominance of light-grey silty-clay deposits with a mean grain-size of 5.70 to 6.21 phi, sometimes with thin intercalations of coarse-grained sands and gravels. Chemical analyses shovedthat these deposits contain mostly silicates with small admixtures of Ca and Mg, and that they reflect the geological structure of the area.}, type={Article}, title={Sedimentation in small proglacial lakes in the Hörbyebreen marginal zone, central Spitsbergen}, URL={http://www.journals.pan.pl/Content/111234/PDF-MASTER/1989_3_385-399.pdf}, }
