the a pproximately s ame pe riods <strong>of</strong> t ime, t o obs erve a ny pos sible de terioration <strong>of</strong> t he<br />

chitin within the silica gel matrix.<br />

Conclusions<br />

Our in itial a ttempts in s ilicification o f in sects w ere successful. Our experiments w ill<br />

elucidate the insect fossilization process in the silicate –rich environments. The IR study<br />

<strong>of</strong> the chitin within the silica matrix will enable us to monitor any possible deterioration<br />

<strong>of</strong> chitin over a period <strong>of</strong> time.<br />

Acknowledgments<br />

Thanks are expressed to the WSGC for a steady support <strong>of</strong> our projects on silicification<br />

in t he a strobiological context. We a re grateful t o D on Lintner f or hi gh qu ality<br />
