“…These results are broadly consistent with both wider Indo-Pacific (Cabioch et al, 1995, Camoin et al, 1997, Montaggioni, 2005 and Caribbean reefs (Neumann and Macintyre, 1985, A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPT Hudson, 1998, Gischler andHudson, 2004), showing both initial vertical accretion and then lateral progradation of the reef flat in response to sea-level stabilisation and reduced accommodation. Differences in the precise timing of when these reefs first approached sea level and the transition to progradational growth at these locations (ranging from 6 ka to 2 ka) are related, in part, to differences in the timing of relative sea-level changes that result from glacial isostatic adjustment or tectonic movement (Lambeck et al, 2010).…”

A re-examination of 46 recently published U/Th reef flat ages from Heron and One Tree reefs in the southern Great Barrier Reef (GBR) identified several distinct Holocene reef growth phases with a clear 2.3-kyr hiatus in lateral reef accretion from 3.9 ka to 1.5 ka. An analysis of all available published radiocarbon reef flat ages (165) from 27 other mid-outer platform reefs revealed a similar hiatus between 3.6 ka and 1.6 ka for the northern, south-central and southern GBR. However, no hiatus in reef flat growth was observed in reefs from the central GBR with ages ranging from 7.6 ka to 0.9 ka. Increased upwelling, turbidity and cyclone activity in response to increased sea-surface temperature (SST's), precipitation and El-Nino Southern Oscillation variability have been ruled out as possible mechanisms of reef turn-off for the midouter platform reefs. Rather, a fall (~0.5 m) in relative sea level at 4-3.5 ka is the most likely explanation for why reefs in the northern and southern regions turned off during this time.Greater hydro-isostatic adjustment of the central GBR and long term subsidence of the HalifaxBasin may have provided greater vertical accommodation for the mid-outer reefs of the central GBR, thus allowing these reefs to continue to accrete vertically despite a fall in sea level ~4-3.5 ka. Further evidence for greater subsidence in this region includes the lack of senile reefs and dominance of incipient and juvenile reefs in the central GBR. This suggests that these reefs approached sea level considerably later than the northern and southern reefs, consistent with their deeper antecedent substrates. Thus, these results not only provide important information about possible reef flat demise in response to natural environmental factors, but also provide insights into regional subsidence that affected relative sea level along the east Australian margin during the Holocene.

“…This situation contrasts with many Caribbean and Pacific areas where massive coral facies commonly replace branching corals facies in the upper sections of reefs (see e.g., Davies and Hopley 1983;Cortes et al 1994;Cabioch et al 1995). Such a succession of coral facies was interpreted as being related to increasing wave energy conditions, as coral head facies usually prevail in high energy conditions while branching corals are thought to characterize lower energy environments (Marshall and Davies 1982).…”

“…Reefs from relatively protected areas (e.g., the Mauritius fringing reef under study) are detritus-dominated, whereas reefs growing in higher energy conditions (e.g. Re´union Island fringing reef and Mayotte barrier reef) are characterized by the prevalence of frameworks, as noted in other Indo-Pacific areas (Davies and Hopley 1983;Montaggioni 1988;Partain and Hopley 1989;Cabioch et al 1995). This pattern is observed within the same reef (e.g., Mauritius), where there is a clear differentiation of framework and biodetrital material from the outer margin shorewards; detrital components (rubble and sand deposits) increase markedly towards the inner parts of the complex (Fig.…”

The sedimentological and chronological study of Holocene reef sequences recovered in drill cores through modern reefs of Mauritius, Re´union Island and Mayotte allows the reconstruction of sea level changes and reef growth patterns during the Holocene. The branching-coral facies systematically predominates over coral head facies throughout the Holocene reef sequences, and Acropora is the main frame builder among the branching forms. The reconstructed sea level curves, based both on identification of coral assemblages and on radiometric U/Th ages, are characterized by a rapid rise between 10 and 7.5 ky BP, followed by a clear inflection between 7.5 and 7 ky BP. The stabilization of sea level at its present level occurred between 2000 and 3000 years ago, probably without a higher sea level stand. Rates of vertical reef accretion range between 0.9 and 7 mm. y\.

“…La plupart des récifs modernes (frangeants et barrières) autour de la Grande Terre de Nouvelle-Calédonie ont commencé à s'édifier vers 9 000-8 000 ans (Cabioch et al, 1995Frank et al, 2006), c'est-à-dire lors de la phase terminale de la dernière remontée du niveau (Taylor et al, 1987), se soulèvent rapidement (Pineda et Galipaud, 1998), d'où l'absence de récifs barriè-res et de lagon, seul un récif frangeant borde de façon continue les côtes est. Les taux de surrection maximaux reconnus durant l'Holocène, 5,5 et 3,4 mm par an, sont localisés respectivement dans les secteurs sud-est d'Espiritu Santo et nord de Malakula (Taylor et al, , 1987.…”

“…Leurs constituants se répartissent, de bas en haut, en deux unités se répartissant en trois assemblages (figure 2) : i) une unité inférieure composée généralement de débris d'Acropora, ii) une unité supérieure constituée de coraux plus ou moins massifs, souvent des Favidés et des Porites (Cabioch et al, 1995). Cette succession est typique d'une croissance dite de rattrapage (catch-up growth mode sensu, Neumann et MacIntyre, 1985), typique d'un rattrapage du niveau marin par le récif lorsque la vitesse de remontée du niveau marin décroît.…”
