ABSTRACT
Marble is not very common in Hong Kong, it accounts for only 3% of the geological area. Despite this fact, marble and the cavities associated, play an important role within the building strategies of the city, being located in areas crucial for the development of new residential areas in Hong Kong. In order to better understand the issue, boreholes from Area 90 in Ma On Shan have been studied. This paper aims to study cavity distribution, size and location along with the rock profile and to provide an overview of the engineering problems associated with this geology. Ma On Shan Formation can be classified according to the current literature along with the risk that might pose to future civil engineering projects.
