Concept
Ma Wan
Summary
Ma Wan is an island of Hong Kong, located between Lantau Island and Tsing Yi Island, with an area of . Administratively, it is part of Tsuen Wan District.
The Lantau Link that passes through Ma Wan was constructed in the mid-1990s as part of the Hong Kong Government's Rose Garden plan to connect the new Hong Kong International Airport to the city centre. Its development fostered plans to develop the island. Today, a large part of Ma Wan is occupied by the Park Island apartment complex. A theme park, named Ma Wan Park was built to accompany the housing project, with its first phase opened on 1 July 2007.
Ma Wan has an area of . Its highest point is Tai Leng Tau () in the southeast. Two channels separate Ma Wan and other major islands.
to the east is the Ma Wan Channel, separating it from Tsing Yi Island. The channel is crossed by the Tsing Ma Bridge.
to the southwest is Kap Shui Mun, separating it from the Tsing Chau Tsai Peninsula of Lantau Island. The channel is crossed by the Kap Shui Mun Bridge.
the north seafront is opposite Tsing Lung Tau and Sham Tseng on the mainland Tsuen Wan District, part of the New Territories.
The south faces the small Tang Lung Chau island.
Ma Wan surface rocks are mostly volcanic rocks called Yim Tin Tsai Formation. This is a coarse ash crystal tuff containing lapilli. Some layers of fine volcanic ash are found in the far north of the island. The contained mafic minerals are biotite and amphibole. The tuff contains mostly quartz and alkali and plagioclase feldspar. Other minerals include apatite, magnetite, monazite and zircon.
The Ma Wan granite is fine grained. It contains microcline, and few feldspar phenocrysts. The main minerals are quartz, perthitic orthoclase, and plagioclase. The dark mineral is mostly biotite. Also contained is zircon, fluorite, and allanite. It is found on the south of the east coast.
Dykes formed later with a mafic dyke injected first followed by a felsic material. A feldsparphyric dyke crosses the island east–west near the ferry pier.
