A Study of Engineering Geological Conditions of Late Quaternary Sedimentary Layers in Coastal Areas of China


Book Description

The characteristics of late Quaternary strata in East China are subject to the tectonic activities and the river-laden sands. On tectonic uplift areas, river loads, mainly composed of coarse sediments, are usually small, and the first kind of late Quaternary strata are developed, characterized by slight thickness and coarse sediments, very thin marine silts, and shallow bedrock. All these factors are favorable for construction of offshore building. Developed on the tectonically continuous depression area, where river loads are large and mainly composed of fine-grained sediments, the other kind of late Quaternary strata are characterized by big thickness, several marine beds, and a striking difference of engineering mechanical properties between marine and facies of land beds, where the beds need to be softened before constructing offshore engineering structures. In terms of types and assemblages for late Quaternary sediments, the coastal areas in China could be classified as three different engineering areas, namely, Area I, II, and III. Area I is distributed from the coast of the Changjiang River to that of Liaohe River except Shandong Peninsula; Area II is made up of the coasts of Fujian, Guangdong, Guangxi Province, Liaodong, and Shandong Peninsula; Area III is made of the coasts in the vicinity of large estuaries on tectonic uplift zones, such as the coast of the Zhujiang River and the coast along Zhejiang province.










A Geological Field Guide to the East and Central Lantau Island


Book Description

This dissertation, "A Geological Field Guide to the East and Central Lantau Island" by Jasim Mohamed Jasim Mohamed, Almardi, was obtained from The University of Hong Kong (Pokfulam, Hong Kong) and is being sold pursuant to Creative Commons: Attribution 3.0 Hong Kong License. The content of this dissertation has not been altered in any way. We have altered the formatting in order to facilitate the ease of printing and reading of the dissertation. All rights not granted by the above license are retained by the author. Abstract: 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.

Petrographic and Borehole Geology Study of Northwest Nearshore Area of Lantau Island


Book Description

This dissertation, "Petrographic and Borehole Geology Study of Northwest Nearshore Area of Lantau Island" by Tsz-ho, Chan, 陳子豪, was obtained from The University of Hong Kong (Pokfulam, Hong Kong) and is being sold pursuant to Creative Commons: Attribution 3.0 Hong Kong License.

All rights not granted by the above license are retained by the author. Abstract: A study of the geology of nearshore area of the northwest Lantau Island has been carried out because of the marine ground investigation work of the Hong Kong-Zhuhai-Macao Bridge. The objective of the study was to recreate a solid geological section of the northwest nearshore area and to resolve some of the discrepancy in the rock name. Data has been obtained from marine ground investigation by method of rotary drilling of rock cores and sampling of soil. Some of the rock specimens have been selected for thin section analysis. The borehole data is presented in the form a data base with projection of GIS software. Petrographic study has been carried out in the selected samples. The data has been interpreted in relation to the onshore geology of the Lantau Island. Which have been detailed in maps and geological memoir published by Geotechnical Engineering Office. (GEO) It is concluded that the area mainly composed of altered granite unit of the Lantau Granite and Chek Lap Kok Granite with minor mafic dyke intrusions. The area is structurally controlled by fault that can be traced onshore. DOI: 10.5353/th_b5677137 Subjects: Petrology - China - Lantau Seashore ecology - China - Lantau
