香港联合国教科文组织世界地质公园

前称中国香港世界地质公园,旧称香港国家地质公园,是一座位于香港新界东部和东北部的地质公园,包括新界东北沉积岩和西贡东部火山岩两大园区等合共8大景区,占地5,000公顷,是罕有位于国际大都会中的世界地质公园。

公园拥有世界一流的酸性火山岩柱,展现了5亿2,000万年至2亿5,000万年前的古生代期间,通过沉积作用形成沉积环境的一段地质历史,极具典型性和稀有性。其中火山岩柱为含硅质较高的酸性流纹火山岩,所占范围为100平方公里(部分是海域),平均直径1.2米,不论就规模和岩石特征皆堪称世界罕见,更特别的是该处的火山岩同时展现凝灰岩和熔岩的特征,对其是如何形成的,地质学家至今仍看法不一,极具科学研究价值。此外,海岸作用在此形成了多种侵蚀和沉积地貌,其中的化石对于了解古老的古生代环境、地理、气候及生物进化提供了线索。

Hong Kong UNESCO Global Geopark

Hong Kong UNESCO Global, 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 widely distributed hexagonal rock columns in Sai Kung, which are of international geological significance, and the northeast New Territories region, which comprises sedimentary rocks formed in different geologic periods, showcasing the complete geological history of Hong Kong.

The geopark is made up of geological sites and local communities distributed across the Sai Kung Volcanic Rock Region and Northeast New Territories Sedimentary Rock Region.
