  abstract = {{S}ediments of the {G}reat {A}strolabe {R}eef lagoon were investigated using a {S}mith-{M}c{I}ntyre grab during the joint {F}ijian-{F}rench {ASTRO} cruise, in april 1994. {T}his preliminary paper focused on carbonated biophase, which was studied through skeletal composition of 25 sediment samples regularly spaced in the lagoon. {C}ounting and identification of the biogenic debris were achieved for each sample on 13 size fractions (3.98, 3, 2, 1, 0, -1, -1.32, -2, -2.32, -3, -3.32, -4 and -4.32 phi). {T}he results indicates that the main constituents of the carbonated biophase of the lagoon are, in order of importance, #{H}alimeda$ plates, foraminifers and molluscs. {T}he lagoon as a whole, is characterized by a {HALIFOR} biofacies and a {H}ali{F}or{P}el sub-facies (#{H}alimeda$-{F}oraminifers-{P}elecypods). {T}hree main types of biofacies are found : #{H}alimeda$ biofacies ({HALIMOL} and {HALIFOR}), a foraminifer biofacies ({FORAMOL}) and molluscs biofacies ({MOLHAL} and {MOLFOR}). {C}oral reefs represent only a small part among the producers of lagoon sediments (7th rank). {T}he excellent state of preservation of the bioclasts suggests a modern or recent sedimentation and a low impact of the hydrodynamic agents at the bottom level. {T}he absence of lithoclasts in the sand fraction indicate a limited terrigenous influence.
