The abstract of the talks

Numerous artefacts have been unearthed from the Neolithic age archeological sites around Hong Kong over the years. Often these artefacts were labeled either stones or ‘jade’ in study reports. Rarely, however, are these ‘jade’ artefacts made from the minerals jadeite or nephrite. The studies reported here aimed to identify the composition and mineralogy of the ‘jade’ artefacts as well as their possible provenance. The findings have also shed lights on the extent of trade and communication of the local people during the Neolithic time.
