Elephant's Rock
The Elephant's Rock is a large boulder of trachyte and andesite, eroded by the atmospheric agents that gave it the shape of an elephant. It is about 4 meters high. The rock is located near Castelsardo, Sardinia, to the left of the old road that led from the hamlet of Multeddu to the village of Sedini Sedini ( sdc, Séddini) is a ''comune'' (municipality) in the Province of Sassari in the Italian region Sardinia, located about north of Cagliari and about northeast of Sassari. It is part of the Anglona traditional subregion. Sedini borders th .... The Elephant's Rock has a great archaeological importance, because two domus de janas, ancient tombs dating back to the pre-nuragic period, have been carved inside.

Trachyte
Trachyte () is an extrusive igneous rock composed mostly of alkali feldspar. It is usually light-colored and aphanitic (fine-grained), with minor amounts of mafic minerals, and is formed by the rapid cooling of lava enriched with silica and alkali metals. It is the volcanic equivalent of syenite. Trachyte is common wherever alkali magma is erupted, including in late stages of ocean island volcanismMacDonald 1983, pp. 51-52 and in continental rift valleys, above mantle plumes,Philpotts and Ague 2009, pp. 390-394 and in areas of back-arc extension. Trachyte has also been found in Gale crater on Mars. Trachyte has been used as decorative building stone and was extensively used as dimension stone in the Roman Empire and the Republic of Venice. Chemical composition Trachyte has a silica content of 60 to 65% and an alkali oxide content of over 7%. This gives it less SiO2 than rhyolite and more (Na2O plus K2O) than dacite. These chemical differences are consistent with the positio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andesite
Andesite () is a volcanic rock of intermediate composition. In a general sense, it is the intermediate type between silica-poor basalt and silica-rich rhyolite. It is fine-grained (aphanitic) to porphyritic in texture, and is composed predominantly of sodium-rich plagioclase plus pyroxene or hornblende. Andesite is the extrusive equivalent of plutonic diorite. Characteristic of subduction zones, andesite represents the dominant rock type in island arcs. The average composition of the continental crust is andesitic. Along with basalts, andesites are a component of the Martian crust. The name ''andesite'' is derived from the Andes mountain range, where this rock type is found in abundance. It was first applied by Christian Leopold von Buch in 1826. Description Andesite is an aphanitic (fine-grained) igneous rock that is intermediate in its content of silica and low in alkali metals. It has less than 20% quartz and 10% feldspathoid by volume, with at least 65% of the fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elephant
Elephants are the largest existing land animals. Three living species are currently recognised: the African bush elephant, the African forest elephant, and the Asian elephant. They are the only surviving members of the family Elephantidae and the order Proboscidea. The order was formerly much more diverse during the Pleistocene, but most species became extinct during the Late Pleistocene epoch. Distinctive features of elephants include a long proboscis called a trunk, tusks, large ear flaps, pillar-like legs, and tough but sensitive skin. The trunk is used for breathing, bringing food and water to the mouth, and grasping objects. Tusks, which are derived from the incisor teeth, serve both as weapons and as tools for moving objects and digging. The large ear flaps assist in maintaining a constant body temperature as well as in communication. African elephants have larger ears and concave backs, whereas Asian elephants have smaller ears, and convex or level backs. Elephants ...

Castelsardo
Castelsardo ( sdc, Castheddu; sc, Casteddu Sardu) is a town and ''comune'' in Sardinia, Italy, located in the northwest of the island within the Province of Sassari, at the east end of the Gulf of Asinara. History Archaeological excavations have showed the human presence in the area of Castelsardo since pre- Nuragic and Nuragic times, as well as during the Roman domination in Sardinia. After the fall of the Western Roman Empire, the monastery of Nostra Signora di Tergu was founded nearby, but the current town originates from the castle built here, in 1102 (or 1270), by the Doria family of Genoa. The castle and the village which gradually formed round it where the seat of the Doria's fiefdom in the island called ''Castel Doria'' or ''Castelgenovese'', until it was conquered by the Aragonese in the 15th century (1448), and named ''Castillo Aragonés'' (''Castel Aragonese''). Except for the Maddalena archipelago, it was the last city in the island to join the Kingdom of Sardinia. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sardinia
Sardinia ( ; it, Sardegna, label=Italian, Corsican and Tabarchino ; sc, Sardigna , sdc, Sardhigna; french: Sardaigne; sdn, Saldigna; ca, Sardenya, label=Algherese and Catalan) is the second-largest island in the Mediterranean Sea, after Sicily, and one of the 20 regions of Italy. It is located west of the Italian Peninsula, north of Tunisia and immediately south of the French island of Corsica. It is one of the five Italian regions with some degree of domestic autonomy being granted by a special statute. Its official name, Autonomous Region of Sardinia, is bilingual in Italian and Sardinian: / . It is divided into four provinces and a metropolitan city. The capital of the region of Sardinia — and its largest city — is Cagliari. Sardinia's indigenous language and Algherese Catalan are referred to by both the regional and national law as two of Italy's twelve officially recognized linguistic minorities, albeit gravely endangered, while the regional law provides ...

Pre-Nuragic Sardinia
The Pre-Nuragic period refers to the prehistory of Sardinia from the Paleolithic until the middle Bronze Age, when the Nuragic civilization flourished on the island. Paleolithic The discovery of Paleolithic lithic workshops indicate a human presence in Sardinia in the period between 450,000 and 10,000 years ago. According to the researchers, a hominid nicknamed "Nur" was the first to colonize the current territory of the island about 250,000 years ago, in the Lower Paleolithic; based on studies of a phalanx found in the Nùrighe caves of Cheremule, the researchers supposed that he may have been a pre-Neanderthal, but some have expressed doubts, assuming a morphological distance from hominids. During the last ice age sea levels were lower by about 130 meters; at that time Sardinia and Corsica formed a single large island, separated from Tuscany only by a narrow arm of sea. The oldest remains of ''Homo sapiens'' in Sardinia date back to the Upper Paleolithic; their tracks ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
