Hong Kong waters, and in view of the environmental, reclamation in recent requirements years often adopted the partially dredge method, that is, a fully dredge seawall with an The major superficial deposits include marine deposits and alluvial deposits . The geology of Hong Kong is dominated by igneous rocks (including granitic rocks and volcanic rocks) formed during a major volcanic eruption period in the Mesozoic era. It made up 85% of Hong Kong's land surface and the remaining 15% are mostly sedimentary rocks located in the northeast New are also a very small percentage (less than 1%) of .
*Hills became islands. Spurs and ridges became headlands. Valleys became water inlets like Tolo Channel. In later parts, we will discuss how Hong Kong's landscape is affected by rock type, internal and external processes, and human activities. Bridges the Gap between Geology and Ground Engineering High-quality geological models are crucial for ground engineering projects, but many engineers are not always at ease with the geological terminology and analysis presented in these models, nor with their implications and limitations. Project engineers need to have a sound comprehension of the geological models .
Hong Kong is dominated by igneous rocks which granite takes up the largest proportion of 85% of the total land area. The remaining area is underlain by sedimentary rocks superficial deposits mainly in the North West area. Other than the above rock types, there still a kind of rock which covers only a small area of Hong. The oldest rocks in Hong Kong, formed by sediments, date back million to million years. Outcropped stratum can only be seen on the north coast of Tolo Channel in Northeastern Hong Kong. In the remote antiquity, stream originating in the southeastern uplands flowed down the hills, bringing sediments to settle at the estuaries.

This report reviews the identification, classification and distribution of the transported superficial deposits commonly encountered in Hong Kong. It also briefly discusses weathering and the formation of residual deposits derived from the parent bedrock types of Hong Kong.
Weathering. Weathering is the alteration and breakdown of rock minerals and rock masses when they are exposed to the atmosphere. Weathering processes occur in situ, that is, in the same place, with no major movement of rock materials involved.
Weathering is a. Hydrothermal alteration, deformation, and weathering are also addressed, and there are sections on superficial deposits and karst.
‘ The book is clearly intended to be user-friendly and achieves a considerable success in this regard, being lavishly illustrated, and setting a very high standard in layout and visual impact. The effects of rock type on Hong Kong's landscape are great. We will look at the three rock types here.
Although all three rock types are found in Hong Kong, igneous rocks are by far the most common, taking up nearly 85% of Hong Kong's rock means the layer of rock on the surface of Hong Kong is mainly igneous rock. Quaternary superficial deposits in Hong Kong primarily consist of hillslope deposits (colluvium), river deposits (alluvium), and offshore deposits (mud and sand).
About 14% of the land surface of Hong Kong is covered by Quaternary deposits greater than 2 m thick.

Center I in Central District of Hong Kong Island, completely decomposed granite was revealed in a number of drillholes to a depth of –70 mPD.
This demonstrated the presence of a zone of deep weathering. Similar deep weathering conditions have been noted further west along the coastal area between Shek Tong Tsui and Kennedy Town.

The Zudong heavy rare earth element (HREE) deposit in South China is the largest regolith-hosted HREE deposit in the world, with a resource of ~17, tonnes (t) of rare earth oxides (REOs) at an average grade of ~ wt % REOs.
Despite more than 40 years of exploration and exploitation, the genesis of this deposit is poorly understood. These mineral deposits are among the most important ores formed by weathering and supergene enrichment is one of the best understood aspects of weathering.

Landscapes exhibit spatial mosaics that form a ‘patchwork’ of varying character and scale across the Earth's surface, and many attempts have been made to recognise and define a hierarchy among land or landscape types. urbanized areas of Hong Kong is mostly granitic or volcanic, and high end bearing capacity can be achieved.
Due to the spheroidal weathering process (Ruxton and Berry ), however, the bedrock surface may not be clearly defined. Hence, local practice relies on the prescriptive procedures of Practice Note PNAP (Hong Kong Government ) is.

A warm humid climate over the last 60 million years has caused deep weathering of rocks across Hong Kong, although much of this material has since been removed by erosion. Weathering along joints and the pattern of faults across Hong Kong as well as subsequent erosion has created the rugged landscape of peaks and valleys which forms the.
Hydrothermal alteration, deformation and weathering are also addressed, and there are sections on superficial deposits and karst. A review by Diamad Campbell (GEO) concludes: The range of lithologies and materials addressed is extensive, and the illustrations in particular comprise a very valuable resource for geologists and engineers working.

The urban area of Hong Kong is of igneous rock form-ation beneath the superficial deposits and a tropical wea-thering soil profiles.
The engineering bedrock, usually de-fined as Moderately Decomposed Rock with a minimum Total Core Recovery of 85% is generally achievable with common modern piling techniques.
Therefore bored piles. For Stonecutters Bridge, Hong Kong, the foundation support is most efficiently provided by bored piles utilising end bearing and friction in the hard rock stratum, which is typically between 45 m and 67 m below ground level on the east side and between 48 m and 75 m below ground level on the west side.Aptly nicknamed ‘Bloody Mary,’ this was considered to be the worst storm to have hit Hong Kong in the 23 years since the Great Hong Kong Typhoon.
The Royal Observatory issued the No. 10 warning signal, though sustained surface winds of kilometres per hour were not observed, as is the international criteria.
