context_page_description: Hong Kong UNESCO Global Geopark, formerly Hong Kong National Geopark, was inaugurated on 3 November 2009. It is a single entity of land area over 150 km² across parts of the eastern and northeastern New Territories. On 18 September 2011, UNESCO listed the geopark as part of its Global Geoparks Network.
  The Hong Kong UNESCO Global Geopark consists of two geological regions:
  the Sai Kung Volcanic Rock Region, with its widely distributed tuff volcanic rocks displaying prismatic columnar jointing, which are of international geological significance
  the Northeast New Territories Sedimentary Rock Region, which comprises sedimentary rocks formed in different geologic periods, showcasing the complete geological history of Hong Kong.
