单词	speleothem
释义	speleothem /ˈspiːlɪə(ʊ)θɛm / noun Geology A structure formed in a cave by the deposition of minerals from water, e.g. a stalactite or stalagmite.Stalactites, stalagmites, and other speleothems - or cave formations - grow as water travels through rocks, dissolves minerals, and then seeps into caves and redeposits those substances.... The most common type of speleothems studied for palaeoclimate are cylindrical stalagmites. Water chemical data are important for palaeohydrological interpretations, but in this case we restrict the discussion to available water data from close to the studied speleothems. Origin 1950s: from Greek spēlaion 'cave' + thema 'deposit'.
