Tafoni
Although various definitions can be found in the scientific literature, tafoni (singular: tafone) are commonly defined as small (less than ) to large (greater than ) cavity features that develop in either natural or manmade, vertical to steeply sloping, exposures of granular rock (i.e., granite, sandstone) with smooth concave walls, and often round rims and openings. Recognized subcategories of tafoni include ''honeycomb'', ''stonelace'', ''alveolar'' (less than ), ''sidewall'', ''basal'', ''nested'', and ''relic tafoni''. It is also commonly synonymous with ''nido d’ape roccioso'' in Italian.Paradise, T.R., 2013. ''Tafoni and other rock basins.'' In: Shroder, J. (Editor in Chief), Pope, G.A., (Ed.), ''Treatise on Geomorphology.'' Academic Press, San Diego, CA, vol. 4, Weathering and Soils Geomorphology, pp.111–126. The etymology of the word ''tafoni'' is unclear. Tafoni may come from the Greek word ''taphos'', ''tomb'', or it may stem from a Corsican or Sicilian word for '' ...

Honeycomb Weathering
Honeycomb weathering, also known as honeycombs, honeycombed sandstone, is a form of cavernous weathering and subcategory of tafoni that consists of regular, tightly adjoining, and commonly patterned cavities that are developed in weathered bedrock; are less than in size; and resemble a honeycombed structure. Honeycombs also been called alveoli, lacework, stonelace, fretting or miniature tafoni weathering.Bruthans, J., Filippi, M., Slavík, M. and Svobodová, E., 2018.

Israel
Israel (; he, יִשְׂרָאֵל, ; ar, إِسْرَائِيل, ), officially the State of Israel ( he, מְדִינַת יִשְׂרָאֵל, label=none, translit=Medīnat Yīsrāʾēl; ), is a country in Western Asia.

Israel also is bordered by the Palestinian territories of the West Bank and the Gaza Strip to the east and west, respectively. Tel Aviv is the economic and technological center of the country, while its seat of government is in its proclaimed capital of Jerusalem, although Israeli sovereignty over East Jerusalem is unrecognized internationally. The land held by present-day Israel witnessed some of the earliest human occupations outside Africa and was among the earliest known sites of agriculture. It was inhabited by the Canaanites ...

Negev
The Negev or Negeb (; he, הַנֶּגֶב, hanNegév; ar, ٱلنَّقَب, an-Naqab) is a desert and semidesert region of southern Israel. The region's largest city and administrative capital is Beersheba (pop. ), in the north. At its southern end is the Gulf of Aqaba and the resort city and port of Eilat. It contains several development towns, including Dimona, Arad and Mitzpe Ramon, as well as a number of small Bedouin towns, including Rahat and Tel Sheva and Lakiya. There are also several kibbutzim, including Revivim and Sde Boker; the latter became the home of Israel's first Prime Minister, David Ben-Gurion, after his retirement from politics. Although historically part of a separate region (known during the Roman period as Arabia Petraea), the Negev was added to the proposed area of Mandatory Palestine, of which large parts later became Israel, on 10 July 1922, having been conceded by British representative St John Philby "in Trans-Jordan's name".

Cambrian
The Cambrian Period ( ; sometimes symbolized C with bar, Ꞓ) was the first geological period of the Paleozoic Era, and of the Phanerozoic Eon. The Cambrian lasted 53.4 million years from the end of the preceding Ediacaran Period 538.8 million years ago (mya) to the beginning of the Ordovician Period mya. Its subdivisions, and its base, are somewhat in flux. The period was established as "Cambrian series" by Adam Sedgwick, who named it after Cambria, the Latin name for 'Cymru' (Wales), where Britain's Cambrian rocks are best exposed. Sedgwick identified the layer as part of his task, along with Roderick Murchison, to subdivide the large "Transition Series", although the two geologists disagreed for a while on the appropriate categorization. The Cambrian is unique in its unusually high proportion of sedimentary deposits, sites of exceptional preservation where "soft" parts of organisms are preserved as well as their more resistant shells. As a result, our understanding of the Ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isle Of Skye
The Isle of Skye, or simply Skye (; gd, An t-Eilean Sgitheanach or ; sco, Isle o Skye), is the largest and northernmost of the major islands in the Inner Hebrides of Scotland. The island's peninsulas radiate from a mountainous hub dominated by the Cuillin, the rocky slopes of which provide some of the most dramatic mountain scenery in the country. Slesser (1981) p. 19. Although has been suggested to describe a winged shape, no definitive agreement exists as to the name's origins. The island has been occupied since the Mesolithic period, and over its history has been occupied at various times by Celtic tribes including the Picts and the Gaels, Scandinavian Vikings, and most notably the powerful integrated Norse-Gaels clans of MacLeod and MacDonald. The island was considered to be under Norwegian suzerainty until the 1266 Treaty of Perth, which transferred control over to Scotland. The 18th-century Jacobite risings led to the breaking-up of the clan system and later cleara ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
