Atolls are faithful recorders helping us understand eustatic variations, the evolution of carbonate production through time, and changes in magmatic hotspots activity. Several early Cretaceous Mid-Pacific atolls were previously investigated ocean drilling, but due to low quality vintage seismic data available, few spatial constraints exist on their stratigraphic large-scale diagenesis. Here, we...

ABSTRACT Submarine slopes prograde via accretion of sediment to clinoform foresets and degrade in response channel or canyon incision mass-wasting processes. The timescales over which progradation degradation occur, the large-scale stratigraphic record these processes, remain unclear due poor age constraints subsurface-based studies areally limited exposures exhumed systems. We here integrate 3...

The paleoenvironmental impact of the early Aptian Ocean Anoxic Event 1a (OAE 1a, ca. 121 Ma) has been investigated in detail Cismon Core (Lombardy Basin, western Tethys) by using different geochemical and micropaleontological proxies. We provide first high-resolution data benthic foraminiferal assemblages through upper Barremian - lower stratigraphic interval. Benthic foraminifera are integrate...

Employing IT as the key enable technology, virtual organization (VO) is primarily characterized as being a network of independent, geographically dispersed organizations (member organization) providing electronic services via Internet. To align these services effectively, one of the main challenges is to model cooperation in VO and provide correspondent management tools. Here we present a VOC (...

We report herein five new coordination polymers of general formula [LnNa(C(6)H(5)CO(2))(4)] where Ln = Y (6), Tb (7), Er (8), [DyNa(CH(3)CO(2))(4)(MeOH)] (9) and [DyNa(C(3)H(7)CO(2))(4)] (10). Single crystal structure analyses revealed that all compounds have a repeating unit containing one Ln(3+), one Na(+) and four monocarboxylate ligands (RCO(2)(-)) (R = -CH(3), -C(3)H(7), -C(6)H(5)). Compou...
