A light vibracorer: construction, utilization and potentialities

Abstract

Undisturbed or minimally disturbed cores are very hardly obtainable from soft sedimentary deposits, mostly of Quatemary age. On the other hand, details of primary structures must be preserved making possible to reconstruct, as perfect as possible, their sedimentary environments. A very light and cheap vibracorer, suitably used for coring clayey-sandy organic sediments, like bay-bottom, lacustrine or lagoonal deposits, is here described.
