Plage de Lanséria Live Cam

Geological Origins

Perched along the Atlantic coast of Loire-Atlantique, Plage de Lanséria in Mesquer is a testament to millennia of coastal evolution. Composed predominantly of fine quartz sands, this beach emerged during the Holocene epoch as rising sea levels sculpted dunes and inlets. Beneath the surface, sediments reveal a stratified record: clay deposits from estuarine incursions alternate with wind-blown aeolian sands, marking periodic climatic shifts. For geology enthusiasts searching for “Beaches Loire-Atlantique geology” or “Atlantic dune formation,” Lanséria offers visible cross-sections where tidal dynamics and prevailing westerly winds converge to shape the shoreline.
