The North-Marchean Apennines (central Italy) host an extraordinary geological and geomor-phological heritage, significant for its richness, diversity, rarity, scientific interest, aesthetic ap-peal, naturalistic, cultural, and educational values. The area, which covers 600 square kilometres and includes numerous spectacular geosites, embraces 18 municipalities in the provinces of Pesaro-Urbino and Ancona. These municipalities are distributed along the ridge that includes the peaks of Mts. Strega, Catria, Acuto, Petrano, Tenetra and Nerone and covers the parallel ridge of Mts. Paganuccio-Pietralata, together with the spectacular Furlo Gorge. It is a real geological museum outdoors, which, with its continuous stratigraphic succession of 200 million years, its geosites, and a vast system of karstic caves, is distinctive for geologists all over the world. This study aims to analyse the environmental heritage of the North-Marchean Apennines through the integrated study and description of the geo-environmental aspects of 7 geosites, se-lected from a list of 44, presented here and localized. These 7 geosites were chosen as being par-ticularly significant from a scientific, naturalistic as well as aesthetic, and cultural point of view. The richness of its geological and geomorphological heritage and the great wealth of its naturalistic, historical, and cultural aspects make it an area with high educational, tourist and recreational potential.

This work is aimed at showcasing one of the most engaging geoparks in Europe, the Gole della Breggia Geopark. By following its geotrail, the visitors can observe a great deal of features that encompass a wide variety of sedimentary, stratigraphic, tectonic and paleogeographic processes. Its contents are valorized by a comprehensive geotrail that encompasses 23 geostops, enriched with explanatory panels, which enable viewers to gain an overall picture of the complex processes that led to the present-day configuration of the outcrops encountered in the Geopark. We have selected five significative outcrops, which we have regarded as fully-fledged geosites, and which encompass the whole 170-million-year interval, from Early Jurassic to Late Miocene times, during which the rocks of the Geopark were deposited and deformed. We have performed an assessment of the five geosites, using the most common criteria that can be applied for geosite evaluation. The result of the assessment show that the most valuable geosite is the Lombardian Maiolica, highly representative of a pelagic limestone, which is rich in fossil contents, marked by integrity, scien-tific interest and has a major educational value. All geosites, thanks to a QR code added to each figure along the text, can be viewed as Virtual Geosites (VGs), integrated by 360° videos.

Las Loras UNESCO Global Geopark (UGGp) is geologically diverse, particularly in relation to water-derived features: springs, karst springs, travertine buildings, waterfalls, caves. In this work, the interactions between geology, geomorphology, structures and hydrogeology are analyzed. These four components are the fundamentals of geodiversity and their interactions provide a conceptual model of hydrogeological functioning at Las Loras UGGp. The most plausible hypothesis is that the system is formed by two superimposed aquifer systems, separated by an aquitard formed by Lower Cretaceous material. The deep lower aquifer formed by the Jurassic limestones only outcrops on the northern and southern edges of the Geopark and in a small arched band to the south of Aguilar de Campoo. It forms a basement subject to intense deformation. The upper aquifer system, formed by outcropping materials from the Upper Cretaceous, is a free aquifer. It is formed by a multilayered aquifer system that is highly compartmentalized by the very disturbed geomorphology of the landscape, constituting each moorland and each lora, an individualized recharge-discharge system. This model explains the base level of the rivers, the abundant number of existing springs and the permanent nature of some rivers, providing the keys to understand the bases of the geoconservation of a rich geological heritage linked to the active processes of the water cycle.
