Abstract

A detailed study of the crystal building blocks of Porites Lutea corallites was performed using transmission electron microscope (TEM) and applying a preparation method that preserved the original microstructure of the skeleton. Bundled acicular aragonite crystals could be identified and were found to be of high structural quality. These tens of mu m long needle shaped crystals were in general electron transparent - indicating a thickness well below 500 nm - and covered by an amorphous, possibly organic matrix. The growth of the orthorhombic crystal needles was found to proceed preferentially along <100 > directions with the <010 > and <001 > growth directions being inhibited. The width distribution of these needles shows a multimodal behaviour, which could indicate a multi-stage nucleation process throughout the skeleton formation.
