Of, found in, or produced by a river.‘fluviatile sediments’
- ‘Recent analyses that have shown that detrital zircons can be transported considerable distances in fluviatile environments, implying laterally extensive drainage systems.’
- ‘Second, reconstruction of some of the sediments as deposited by fluviatile action suggests that fluvial transport affected the assemblages.’
- ‘The conglomerate was deposited in a fluviatile environment and contains clasts of mafic to felsic volcanic rocks, green sericitic slate, siltstone, wacke, granite, jasper, perthitic feldspar, albite and quartz.’
- ‘These may be of fluviatile, glacial, periglacial, lacustrine, aeolian, or marine origin.’
- ‘The Fossil Bluff Group consists of fossiliferous, shallow marine to sub-aerial fluviatile sandstones and conglomerates of probable fore-arc origin.’
Late 16th century: from French, from Latin fluviatilis, from fluviatus wet from fluvius river.
