 普罗旺斯高地联合国教科文组织世界地质公园位于法国东南部,阿尔卑斯山和普罗旺斯之间,是法国最大的露天地质博物馆。它是法国首批被联合国教科文组织认定为具有国际重要地质遗迹的地区,属于分布在35个国家的127家联合国教科文组织世界地质公园之一,这127家公园都属于世界地质公园网络的机构成员。
普罗旺斯高地联合国教科文组织世界地质公园拥有18个超过3亿年历史的地质遗迹,其中包含丰富的化石遗迹和迷人的岩层。在35万平方米的石灰岩墙上保存了1,550多颗菊石,同时也发现了鸟类足迹化石和植物化石。维登河峡谷可以欣赏到普罗旺斯高地美丽的风光。这是法国最壮观的峡谷,全长21公里,两岸是高达700米的悬崖峭壁。这些都面向学生们开放,供他们学习、发现并了解保护地质遗迹的必要性及重要意义。
普罗旺斯高地联合国教科文组织世界地质公园向人们展现了地球3亿年的历史。整个地区都被从石炭纪(3亿年前)到现今的沉积岩所覆盖。主要的不整合发生在石炭纪中期-下三叠统之间(3亿年-2.5亿年前)以及晚侏罗-始新世晚期之间(1.4亿至3.5亿年前)。中生代的岩石展现了地质历史上的特提斯裂陷作用,沉积物为碳酸盐岩到盆地泥灰岩到各种岩相提供了证据。两个独立的构造事件分别与海洋盆地的封闭以及普罗旺斯山脉、阿尔卑斯山脉形成有关。普罗旺斯高地联合国教科文组织世界地质公园为公众提供了大量独特的地质遗迹热点(菊石岩墙,鸟的足迹化石,地貌景观),她在欧洲建立了第一个保护古生物化石标本的博物馆(1980年,鱼龙,La Robine)。公园内地质遗迹作为国家地质遗迹资源得到严格保护。

Located in south-eastern France, between the Alps and Provence, the Haute-Provence UNESCO Global Geopark is the largest geological open-air museum in France. 
It was first recognized by UNESCO as area with geoheritage of international importance in France and belongs to the 127 UNESCO Global Geoparks laying in 35 countries. They are all institutional members of the Global Geoparks Network.
The Haute-Provence UNESCO Global Geopark includes 18 geological sites more than 300 million years old, which contain numerous fossil-rich materials and fascinating rock formations. More than 1,550 ammonites are preserved on a 350,000 square metre limestone wall. Fossilized footprints of birds can be found, as well as fossilized plants. The Verdon river gorge offers the opportunity to discover the beautiful landscape of Haute- Provence. It is the most spectacular of the French canyons, 21 km long with 700-metre-high cliffs. The geological reserve is open to students who can discover and learn about geological heritage, as well as the necessity and the meaning of protecting it.
The Haute-Provence UNESCO Global Geopark is a place showing 300 million years of the Earth’s history. The entire territory is occupied by sedimentary rocks ranging in age from the Stephanian (300 million years ago) to present. Major unconformities are recorded between Middle Stephanian - Lower Triassic (300-250 million years ago) deposits and between the late Jurassic - late Eocene successions (145-35 million years ago). The Mesozoic rocks exhibit the history of the Tethyan rifting and the sediments give evidence of a great variety of facies ranging from barrier reef carbonates to basin marls. Two separate tectonic events were associated with the closure of ocean basins and the formation of the Provencal Mountain Chain and the Alpine Chain respectively. The Haute-Provence UNESCO Global Geopark offers a great quantity of geological unique hotspots (ammonite slab, bird footprints. landscapes.) and has created the first site museum in Europe build to protect a paleontological specimen (1980, Ichthyosaurus, La Robine). In its territory the geological heritage is strictly protected by a National Geological reserve.
