This 10 centimetre giant is a pioneer of marine conquest. All summer, glassworts (Salicornia europaea) will be rhythmically swept by the tide, gradually trapping seaborne sediment on the shores of Aberlady Bay in Scotland. The resulting elevation of the mudflat marks the start of a race of growth against waves, currents and sea level rise, eventually leading to the development of a salt marsh. How ...[Read More]

In this case the geothermal fluids come from the Late Miocene Porto Azzurro monzogranite, and Mesozoic marble ...[Read More]
