The Mefite site in Ansanto Valley is located in the Rocca San Felice municipality (Province of Avellino, Campania Region, Italy), namely in Irpinia: this region was in ancient times inhabited by Hirpini (the where part of the local tribal system). The site is in the same time inserted in a wide rural landscape preservin0067 still today a high grade of naturality. As regards the geological structures, they are to be quoted at least 55 geosites, object of recent research aimed at identifying Geodiversity in Campania Region. Due to its environmental features, the site of Mefite has been known since antiquity as a site of deadly exhalations and place of manifestation of the eponymous goddess: his name should derive from “meudh,” literally “she who is in the middle”, link between the opposing life/death and heaven/earth. Archeological data witness the presence in V cent. b.C. of a cult referred to the goddess named Mephitis, namely the divinity living in the land of the middle between heaven and infernal word. She was worshipped because of her recognized influence on waters, fertility, and rural life. Probably, in the time of Late Roman Empire, decaying the christian rituals took the place of pagan ones. The long period of silence characterizing Middle Ages was interrupted by the numerous information aquired through the notes reported by common travelers and famous people too. As a matter of fact in the nineteenth century and in the first part of twentieth century, the mephitic phenomena related to the site where associated to the ones taking place in the near Phlegrean area. From this issue derives the theory of a volcanic origin of the place. The existing theory linked to mephitic phenomenology in not universally shared, in the same time we can surely exclude any volcanic origin of the matter but considering the evaluation of some geo- and biochemical elements. The carbon dioxide exceptional amount is related to the emission of some “traps” created during the construction of tectonic Apenninic orogenesis; the weak thermalism of the area and the presence of hydrocarbon are eventually compatible with the explanation given. The very place is a sort of natural lab for studying some endemic species able to survive in extreme survival conditions. Aiming at characterizing the importance and the geotouristic value, the site of Mefite has been evaluated following some appropriate criteria. For instance, making a comparison among different local geosite features using the most widely used assessment methods, through this process is evident that the site of Mefite is absolutely provided of the best qualitative elements in term of scientific, panoramical, and relational potentialities. The opinions so collected suggest some specific policies having the purpose of promoting and preserving the area. In conclusion, this study states that the Mefite is a valuable Geoarcheosite in a major area aiming at respecting and enhancing local traditions and customs to stimulate a kind of a sustainable and responsible geotourism.

安桑托山谷（意大利南部）的Mefite：促进Irpinian文化景观的地质旅游和地质保护的Geoarchaeosite

安桑托山谷的Mefite遗址位于Rocca San Felice自治市（意大利，坎帕尼亚地区，阿韦利诺省），即Irpinia：该地区在古代曾被Hirpini（当地部落系统的一部分）居住。该场地同时被插入到广阔的乡村景观中，至今仍是高度自然的景观。关于地质结构，至少要引用55个地质地点，这是旨在确定坎帕尼亚地区的地球多样性的最新研究的对象。由于其环境特征，梅菲特遗址自古以来就是致命的呼气场所和同名女神的表现场所：他的名字应来源于“默德”，字面意思是“中间的她”在相对的生命/死亡与天堂/地球之间。考古数据见证了V cent的存在。邪教的公元前时期被称为女神，名为“菲菲提斯”，即神性生活在天堂和地狱话之间的中间地带。她之所以受到崇拜是因为她对水，肥力和农村生活的公认影响。可能是在罗马帝国晚期时期，腐朽的基督教仪式取代了异教徒的仪式。中世纪特征的长期沉默被普通旅行者和著名人士所报道的笔记中获得的众多信息所打断。事实上，在19世纪和20世纪上半叶，斑驳的现象与该地点相关，而该地点与发生在Phlegrean地区附近的地点有关。从这个问题可以得出该地方火山起源的理论。现有的与尚观现象学相关的理论并没有得到普遍认可，同时我们可以肯定地排除该物质的任何火山成因，但可以考虑对某些地球化学和生化元素的评估。二氧化碳超量与构造构造亚平生造山运动过程中产生的一些“陷阱”的排放有关。该地区的弱热性和碳氢化合物的存在最终与所给出的解释是相容的。该场所是研究某些能够在极端生存条件下生存的地方物种的自然实验室。为了表征重要性和地质旅游价值，已根据一些适当的标准对梅菲特遗址进行了评估。例如，通过使用最广泛使用的评估方法对不同的本地地理特征进行比较，通过此过程，很明显，就科学，全景和关系潜力而言，Mefite站点绝对具有最佳的定性元素。如此收集的意见提出了一些旨在促进和保护该地区的具体政策。总而言之，这项研究指出，梅菲特矿山是重要地区的重要地质古迹，旨在尊重和增强当地的传统和习俗，以激发一种可持续发展和负责任的地质旅游。这样收集的意见提出了一些旨在促进和保护该地区的具体政策。总而言之，这项研究指出，梅菲特矿山是重要地区的重要地质古迹，旨在尊重和增强当地的传统和习俗，以激发一种可持续发展和负责任的地质旅游。如此收集的意见提出了一些旨在促进和保护该地区的具体政策。总而言之，这项研究指出，梅菲特矿山是重要地区的重要地质古迹，旨在尊重和增强当地的传统和习俗，以激发一种可持续发展和负责任的地质旅游。
