Downtown Hong Kong is absolutely a haven for geologists interested in minerals and rocks, because of the rich varieties of stones that were used as exterior claddings.
Much can be learnt from the mineralogy and textures of the cladding stones. For instances, the facade stone in World Wide House is a rapakivi granite showing plagioclase rims surrounding rounded orthoclase megacrysts. The floor panel of Pacific Place is a turbidite from Italy, displaying very interesting sand wave patterns of density currents.
The stone outside Senior Common Room in HKU comes from the world-famous ammonite-bearing Rosso Ammonitico formation. However, facade
stones in Hong Kong sometimes show problems of deformation, spalling, unsightly stains, tenting
and efflorescence.
The speaker recently undertook several studies on facade stones and will discuss
how each type of problems may arise in this presentation.
