“…This article concerns the weathering and origin of an autochthonous blockfield in the northern Swedish mountains. Autochthonous blockfields are coarse, blocky mantles produced by in situ weathering, and occur in many periglaciated landscapes (Dahl 1966;Ives 1966;Caine 1968;Clapperton 1975;Clark & Ciolkosz 1988;Nesje et al 1988;Kleman & Borgstr¨om 1990;Ballantyne 1998;Dredge 2000;Boelhouwers 2004;Sumner & Meiklejohn 2004;Firpo et al 2006;Goodfellow 2007). In formerly glaciated settings, autochthonous blockfields frequently indicate surfaces that have not been significantly modified by glacial processes, because they either protruded as nunataks above surrounding ice sheets or were protected by cold-based ice covers (Ives 1958;Sugden & Watts 1977;Nesje 1989;Kleman & Borgstr¨om 1990;Ballantyne et al 1998;H¨attestrand & Stroeven 2002;Marquette et al 2004;Fjellanger et al 2006).…”

The weathering and origin of an autochthonous blockfield in the northern Swedish mountains were investigated through an examination of fine matrix and clasts from two pits excavated across ridge‐top sorted circles; one on a summit, the other in a saddle. At the summit, fine matrix chemical weathering is limited to the production of poorly crystallized Al‐ and Fe‐oxyhydroxides, whereas some additional vermiculitization and gibbsite crystallization occurs in the saddle. In both locations, volumes of clay‐sized matrix are low, mass balance calculations indicate only minor elemental losses and no chemically etched grains are visible under a scanning electron microscope (SEM). In addition, soil horizons are absent and chemical weathering intensity is uniformly low across both excavated sorted circles. Minor clast chemical weathering consists of Fe oxidation, which dominates in the matrix‐rich circle centres, and some rind development, which increases in frequency in the clast‐rich rings. The dominance of physical weathering processes and the presence of only minor chemical weathering, in both fine matrix and clasts, indicate that the blockfield is not a Neogene weathering remnant. Rather, the blockfield has a Quaternary origin, developing during interglacials, interstadials and the Holocene, primarily through subsurface weathering processes.

“…From the geomorphological point of view, the Geopark area presents important forms derived from a periglacial environment (blockstream and blockfields) (Firpo et al 2006) and evidence of sea level fluctuation such as the marine terraces located in the coastal tract situated between the towns of Arenzano and Varazze (Carobene and Firpo 2002;Vacchi et al 2009;Figs. 4 and 5).…”

The consequence of assessing the natural and cultural heritage of a territory is the need of tools for their management. The European Geoparks Network and the Global Geoparks Network (assisted by UNESCO) have the function to provide these tools, aiming at promoting the sustainable development of a territory through the valorization and conservation of its natural and cultural heritage. Becoming an international recognised Geopark in 2005, the Beigua territory has gathered increasing attention from local authorities, tourism operators, entrepreneurs, universities and research institutions, schools, volunteers and environmental associations. During the last 5 years Beigua Geopark developed several projects and acted to raise public awareness on nature conservation. Thanks to effective collaboration with geoscientists, local authorities and tourism organisations, Beigua Geopark set up a structured network of interpretation facilities to support geotourism activities. In this direction, Beigua Geopark also launched an organised touristic offer. Connecting landscape, cultural heritage, sports facilities with unique geological and geomorphological features, Beigua Geopark presents multiple services to encourage both local and regional sustainable development.

“…Besides the folds, faults are extensively developed in specific directions: The E-W, the ENE and WNW trending faults are the masters with almost a dextral-sense of movement, while those of NW trend are normals. N-S, NNE and NNW sinistral-slip faul ts and NE thrusts are subordinately developed [20][21][22][23]. The en echelon arrangement of both folds and faults in addition to the restriction of deformation in certain narrow belts; weak development of the conjugate sinistral-slip faults and conspicuous rotation of the structural elements indicate a dextral shear-couple.…”

Egypt contains Geologic Heritage that create much opportunity to develop educational and recreational programs as well as tourism projects. Enhancement of Geologic Heritage and awareness of the importance of Geologic Heritage is a great challenge. This paper focuses on a neglected area inside Cairo that is facing a great destruction from the people living there. The Abu-Roash archaeological site is located at 31ᵒ 02′ 42″ E longitude and 30ᵒ 02′ 42″ N latitude. It is one of the most important areas for education and scientific study inside Cairo. Although the area is not suited as a geo-heritage or even a protected area, it contains Cretaceous to upper Eocene sedimentary beds and fossils, and a great variety of structural features. Not only an important geologic aspect found in the area but also an archeological site is present which provide the area of a great scientific, cultural/historical, aesthetic and/or social/economic value. These different criteria qualifies the study are to have a regional/provincial rank for its Geo-heritage. Abu Roash area are possess good geo-diversity, geo abundance and geo richness which lead us to start point for establishing potential geo-heritage that should be conserved the area also need to be recognized as a geological conservation sites, the area should be Stated as a protected area of a heritage legislation to protect geo-heritage.
