This field guide has been carried out to fulfil part of the requirements of my master’s degree in the field of Applied Geosciences at the University of Hong Kong. The project was mainly written from September 2012 to July 2013 under the supervision of Dr. Jason R. Ali. The objective of the study was to produce a simple, easily understood, geological guide of areas on eastern and central Lantau Island. The guide intends to introduce useful, fundamental concepts of geomorphology and geology to everyone who visits the selected study areas. Data has been obtained by a literature survey, interpretation of aerial photographs, use of geological and topographic maps and much fieldwork. The information is presented in the form of a simple field guide divided into four chapters. Chapter 1 is the introduction, while Chapter 2 presents background information of the geology of Lantau Island and Chapter 3 is the actual field guide divided into two areas, east Lantau and central Lantau. Chapter 4 concludes this dissertation. It is concluded that Lantau Island exhibits many interesting landscapes and geological features. This field guide provides convenient and easy to understand information for any person, professional or amateur, having an interest in understanding their surroundings (the physical environment) when visiting Lantau Island. / published_or_final_version / Applied Geosciences / Master / Master of Science

Before the year 2000, the sedimentary and volcano-sedimentary rocks on Ma Shi Chau (MSC) have long been regarded as the formations in Permian and Jurassic respectively. Geotechnical Engineering Office (GEO) had modified the geological model and changed the Northeastern side of MSC, the pre-volcanic sedimentary rocks, to an older rock formation, from Permian Tolo Harbour Formation to Devonian Bluff Head Formation. The reasons of change are mainly from structural evidence and lithological evidence. But they are still indirect evidences; no fossil was found in the sedimentary sequences at the hinging wall till to the northwestern shore of Ma Shi Chau. Fossils were only found along the southeastern shore of Ma Shi Chau for the footwall of the reverse fault, which are of Permian age. Through the analysis of the photomicrographs, the Unknown group is difficult to show which formations, the Devonian or Permian is closer to as the Unknown group have similar characteristics of both. For the geochemistry analysis by using different graphs, the patterns of each group are revealed. From the graphs produced, generally the Unknown group have pattern closer to the Permian Tolo Harbor Formation. But there is still no direct evidence that the Unknown group is within the Permian Tolo Harbor Formation. By the geochemical data it is more likely for the Unknown group to be close the Permian rocks. / published_or_final_version / Applied Geosciences / Master / Master of Science
