Imaggeo on Mondays: Alpine Wetland

High altitude wetlands are scenic and unique ecosystems that fulfill important hydrological functions and provide many ecosystem services. They also serve as geo-archives and play a role in greenhouse-gas emissions, just to name a few things.

The photograph has been taken at the Riffelsee (2770 m) near Zermatt, Switzerland. The small lake surrounded by wet-meadows and cottongrass is famous for its reflection of the Matterhorn. In a current project at the Research Unit Sustainability and Global Change in Hamburg distribution and services of such wetlands are evaluated and integrated into interdisciplinary models.

This picture has been taken from the air (small plane) during fieldwork in Alaska during 2009. Oasis valley is located between frontal lobes of Fan and Bremner glaciers (143.57°W; 60.87°N). The orange colour is from sand that have been brought in by the glaciers, and carved by rivers.

Imaggeo on Mondays: Tethys Himalaya

Tethys Himalaya are one of the zones of the Central Himalayan Domain (CHD), which is one of the tectonic zones of the Himalaya. The Tethys Himalaya is approximately 100 km wide large fold (syncline) with superimposed smaller folds (this is known as a synclinorium). The Tethys Himalaya contains a stratigraphic record which indicates the geological history of this part of the Indian continent.

This image shows Palaeozoic and Triassic sediments of the Tethys Himalaya in Zanskar, Jammu & Kashmir. The orange cliffs are massive dolomite from the Cambrian Karsha formation. They are overlain by dark Permian basaltic flows (Panjal Traps). The summit in the middle of the picture consists of Triassic sediments from the Lilang Group. This view from Purne is towards the northeast into the gorge of the Phugtal monastery. A chorten (or stupa) stands in the foreground.
