★ Vulcanicity
There was mainly intrusive vulcanicity in Cheung Chau.According to our textbook chapter1.3, magma enters cracks or chambers in the crust from asthenosphere. When magma cools and solidifies in the crust, it becomes a batholith, dyke,sill or laccolith. Batholith and dyke are mainly found in Hong Kong and Cheung Chau as well.
