Holocene sedimentary rocks in Mathiesondalen, central Spitsbergen, Svalbard

Holocene lithified sediments of glacial and glaciofluvial origin have been found in environments where carbonate cementation is a present-day process. The rocks occur as well cemented tillites, conglomerates, coarse sandstones and breccias, indicating a complex depositional pattern within a limited area. Both clasts and carbonate cement are mainly derived from underlying Carboniferous and Permian sequences which form the bedrock of this area.
