Abstract
Applying geological techniques to archaeological problems such that physical and cultural landscapes of the past can be reconstructed.
Develop a framework for the geological investigation of archaeological ceramic materials
Petrography and Geochemistry: (1) Compilation of a Preliminary Dataset; (2) Results show a correlation of typology to composition, but artefact assemblages across Hong Kong do not reflect source area
Conclusion: This approach is useful to provenance studies, although conclusive results require further work.

14. Site Selection Lung Kwu Tan Sha Ha Jurassic and Cretaceous aged volcanics dominantly rhyodacite to rhyolite coarse ash crystal tuff belonging to the Long Harbour Formation of the Repulse Bay Group. Jurassic and Cretaceous age granite belonging to the Tsing Shan Formation
15. Techniques Fabric Analysis Hand Sample Examination Natural Face Description Petrographic Descriptions Break sherd Thin Section Preparation Inclusions: Rock Fragments, Minerals, Grogs etc Matrix: C/F Ratio, voids, cracks, structure/texture
16. Techniques Geochemical Analysis Sample collection Wash in warm hydrochloric acid Ground to powder using agate mortar 0.025 gm for ICP-MS 1 gm for EDAX (ANU)
28. Geochemical Signature of Compositional Groups Bivariate Plot of Sr vs Sc. Circles define compositional fields for fabric groups A, B and C respectively. Data reported in ppm.
29. Bivariate Plot of Ba vs Rb. Circles define compositional fields for fabric groups A, B and C respectively. Data reported in ppm.
30. Bivariate Plot of Sr vs Rb. Circles define compositional fields for fabric groups A, B and C respectively. Data reported in ppm.
