Summary:Thick continuous hyaloclastic sections consisting of layered debris-flow deposits, turbidites, base surge and fallout deposits as well as sheet and pillow lavas are interpreted as having been formed in large stable lakes rather than beneath ice as formerly supposed. Deep water facies are distinguished from hydroclastic shallow water and emergent facies. Deposits still thought to be subglacial are coarser grained, more poorly sorted and more strongly palagonitized tuffs and breccias probably formed in small chimney-like ice cavities or ice-bound lakes.
