carbonates passing upward into fore-reef, reef, back-reef, and lagoonal
carbonates. Slope strata contain wackestones and packstones with
submarine-cemented lithoclasts, coral, coralline algae fragments,
benthic rotaline forams, planktonic forams, and echinoderm fragments.
Fore-reef strata are dominantly packstones and boundstones containing
large pieces of coral,
abundant benthic forams,
coralline algae
fragments, stromatoporoids(.), and minor planktonic forams. Reef and
near-reef sediments include coralgal boundstones and grainstones with
abundant benthic forams. Halimeda and miliolid forams are common in
lagoonward parts of the back reef. Sponge borings, geopetal structures,
and fractures are common in reef and fore-reef strata. Lagoonal strata
are wackestones and packstones with common mollusks, coral, coralline
algae,
and benthic forams
(rotaline and miliolid).
Diagenesis has
extensively altered strata near the atoll margin. Aragonite dissolution
and calcite cements
fore-reef,
reef,
(radiaxial and cloudy prismatic are abundant in
and some back-reef strata).
Petrographic and
geochemical data indicate arogonite dissolution and calcite cementation
in seawater at burial depths of 100 to 300 m. Dolomite occurs in slope
and deeply buried reefal carbonates.

Calculations have been executed by means of the MARKAL-model for
the Dutch energy economy with exogenous national CO/sub 2/ emission
limits. Starting points are the EOS-scenarios 'Dynamic and Growth’ (DG)
and ‘Partial Development’ (Gedeelde Ontwikkeling or GO) for the period
1989-2020. The model has been adjusted for the transport sector and
altered with regard to CO/sub 2/. These alterations are discussed here.
