Biocalcification processes in three coralline sponges from the Lizard Island Section (Great Barrier Reef, Australia): The Stromatoporoid Astrosclera, the Chaetetid Spirastrella (Acanthochaetetes) and the Sphinctozoid Vaceletia (Demospongiae)
(Geol. Inst. der Georg-august-Univ., 1996)
The main biocalcification events in the phylogenetically
distinct taxa Astrosc/era, S. (Acanthochaetetes) and Vace/
etia are described. Each taxon constructs its secondary

Biogeochemistry of modern Porifera and microbialites from Lizard Island (Great Barrier Reef, Australia) and fossil analogues
(Geol. Inst. der Georg-august-Univ., 1996)
Organic geochemical techniques were applied to study
the lipid conte nt of living reef organisms and rock sampies
trom different carbonate facies. The characterization of individual
organic compounds ("biomarkers") ...
