PAGES Varves Working Group

The Varves Working Group (http://pastglobalchanges.org/ini/end-aff/varves-wg/intro) has released an online image portal summarizing existing varve images around the world. It includes examples of seasonal sedimentary successions, specific sediment components and structures of varved sediments. Different varve types from all continents are visualised by macroscopic, microscopic and X-radiographic images with corresponding metadata.
