 波希米亚天堂联合国教科文组织世界地质公园位于距离布拉格东北部约一百公里的地方。作为联合国教科文组织认可的第一个捷克共和国具有国际重要地质遗迹的地区,波希米亚天堂地质公园属于分布在35个国家的127个教科文组织世界地质公园成员之一。他们都是世界地质公园网络的机构成员。
波希米亚天堂联合国教科文组织世界地质公园拥有众多的地质、矿产以及考古资源,并包含了捷克境内一些最引人入胜的景观。波西米亚天堂联合国教科文组织世界地质公园是一本优秀的地学教科书。同瑞雅克洋(Rheic Ocean)开启有联系的下古生界裂谷与Železný Brod火山杂岩(约5亿年前)的沉积及火山活动息息相关。紧随晚泥盆世俯冲之后的是下石炭统的大陆碰撞。晚石炭世和二叠纪的岩石展现了本地区最古老的陆地火山活动(约2.9亿年前)。一条东西向的凹陷在晚石炭世和二叠纪的沉积以及火山岩中消失。白垩纪海洋沉积为闻名世界的砂岩奠定了基础。大约1700万年-500万年前的第三纪时期发生了强烈的火山活动。几个单成因火山和许多火山特征,比如柱状连接、火山岩、湖泊和火山岩脉等都具有国际地质意义。在火山岩的杏仁体以及细脉中可以发现石英、玛瑙和碧玉。由砂岩组成的“岩石城市”,如Hruba Skala,Bethlehem Rocks,Klokoci Rocks和Prihrazy Rocks,形成了独特的地貌景观。本地区还发现了罕见的白云石洞穴,同时矿物、宝石以及动植物的化石遗迹也闻名世界。

The Bohemian Paradise UNESCO Global Geopark is located nearly one hundred kilometers to the northeast from Prague.
As the first recognized by UNESCO areas with geoheritage of international importance in Czech Republic, it belongs to the 127 UNESCO Global Geoparks laying in 35 countries. They are all institutional members of the Global Geoparks Network.
Bohemian Paradise UNESCO Global Geopark shows a wide range of geological, mineralogical and archaeological features and contains some of the most interesting landscapes in the Czechia. Bohemian Paradise UNESCO Global Geopark represents an excellent geologic textbook. The Lower Paleozoic rifting related to the opening of Rheic Ocean was associated with sedimentation and volcanic activity of the Železný Brod Volcanic Complex (about 500 million years ago). The Late Devonian subduction was followed by Lower Carboniferous continental collision. The oldest terrestrial volcanism (about 290 million years ago) is present by Late Carboniferous and Permian rocks. An east-west oriented depression started to subside in Late Carboniferous and Permian- sedimentary and volcanic rocks. Sediments of Cretaceous sea created foundations of world-known sandstone rocks. An intensive volcanic activity occurred in the Tertiary about 17 – 5 million years ago. Several monogenetic volcanoes and many volcanic features such as columnar jointing, volcanic tubes, lakes and veins have international geological relevance. Quartz, agates and jaspers can be found in amygdales and veinlets of the volcanic rocks. Sandstone “rock cities” such as Hruba Skala, Bethlehem Rocks, Klokoci Rocks and the Prihrazy Rocks form characteristic features in the landscape. Rare dolomite caves are also to be found. The occurrence of minerals, precious stones and petrified remnants of plants and animals are world known too.
