Peperino
Peperino is an Italian word describing a brown or grey volcanic tuff, containing fragments of basalt and limestone, with disseminated crystals of augite, mica, magnetite, leucite, and other similar minerals. The name originally referred to the dark-colored inclusions, suggestive of peppercorns. The typical peperino occurs in the Alban Hills and in Soriano nel Cimino, near Rome, and was used by the ancient Romans under the name of ''lapis albanus'' as a building stone and for the basins of fountains. Other tuffs and conglomerates in Auvergne and elsewhere are also called peperino. In English the word has sometimes been written "peperine". Lazian peperino is a cousin to piperno tuff from Campania Campania is an administrative Regions of Italy, region of Italy located in Southern Italy; most of it is in the south-western portion of the Italian Peninsula (with the Tyrrhenian Sea to its west), but it also includes the small Phlegraean Islan ....

Piperno
Piperno is a particular variety of dimension stone of igneous rock, igneous origin, a tuff or ignimbrite, native to areas in central Italy that have been affected by explosive volcanism, explosive volcanic activity. Piperno abounds in Campania; the areas from which it was obtained were the city of Quarto, Soccavo, Pianura and Nocera Inferiore in the supervolcano region of the Phlegraean Fields. The Piperno layer, with the overlying Breccia Museo, is clearly visible at the base of the Camaldoli hill, in the Soccavo and Verdolino areas. This type of ignimbrite tuff takes on a particular texture characterised by the orientation of lenticular concentrations of grey colour, called flames, immersed in a matrix of the same colour but lighter. Piperno should not be confused with Neapolitan Yellow Tuff; welded piperno tuff is more durable than yellow tuff, which poses conservation challenges. Piperno rock is not easy to extract, and is helped by underground separation of the large bloc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alban Hills
The Alban Hills () are the caldera remains of a quiescent volcanic complex in Italy, located southeast of Rome and about north of Anzio. The high Monte Cavo forms a highly visible peak in the centre of the caldera, but the highest point is Maschio delle Faete approximately to the east of Cavo and taller. There are subsidiary calderas along the rim of the Alban Hills that contain the lakes Albano and Nemi. The hills are composed of peperino (lapis albanus), a variety of tuff that is useful for construction and provides a mineral-rich substrate for nearby vineyards. History The hills, especially around the shores of the lakes, have been popular since prehistoric times. From the 9th to 7th century BC, there were numerous villages (such as the legendary Alba Longa and Tusculum). The area was inhabited by the Latini during the 5th to 3rd centuries BC. The ancient Romans called Monte Cavo Albanus Mons. On the summit was the sanctuary of Jupiter Latiaris, in which the consu ...

Inclusion (mineral)
In mineralogy, an inclusion is any material trapped inside a mineral during its formation. In gemology, it is an object enclosed within a gemstone or reaching its surface from the interior. According to James Hutton's law of inclusions, fragments included in a host rock are older than the host rock itself. Mineralogy Inclusions are usually rock (geology), rocks or other minerals, less often water, gas or petroleum. Liquid and vapor create fluid inclusions. In amber, insects and plants are common inclusions. The analysis of atmospheric gas Bubble (physics), bubbles as inclusions in ice cores is an important tool in the study of climate change (general concept), climate change. A xenolith is a preexisting rock which has been picked up by a lava flow. Melt inclusions form when bits of melt become trapped inside crystals as they form in the melt. Gemology Inclusions are one of the most important factors when it comes to gem valuation. They diminish the diamond clarity, clarity ...

Igneous Petrology
Igneous petrology is the study of igneous rocks—those that are formed from magma. As a branch of geology, igneous petrology is closely related to volcanology, tectonophysics, and petrology in general. The modern study of igneous rocks uses a number of techniques, some of them developed in the fields of chemistry, physics, or other earth sciences. Petrography, crystallography, and isotopic studies are common methods used in igneous petrology. Methods Determination of chemical composition The composition of igneous rocks and minerals can be determined via a variety of methods of varying ease, cost, and complexity. The simplest method is observation of hand samples with the naked eye and/or with a hand lens. This can be used to gauge the general mineralogical composition of the rock, which gives an insight into the composition. A more precise but still relatively inexpensive way to identify minerals (and thereby the bulk chemical composition of the rock) with a petrographic mic ...

Auvergne
Auvergne (; ; or ) is a cultural region in central France. As of 2016 Auvergne is no longer an administrative division of France. It is generally regarded as conterminous with the land area of the historical Province of Auvergne, which was dissolved in 1790, and with the now-defunct administrative region of Auvergne, which existed from 1956 to 2015. The region is home to a chain of volcanoes known collectively as the " chaîne des Puys". The volcanoes began forming about 70,000 years ago, and most have eroded, leaving plugs of hardened magma that form rounded hilltops known as puys. The last confirmed eruption occurred around 4040 BCE. Geography Auvergne is known for its mountain ranges and dormant volcanoes. Together the Monts Dore and the Chaîne des Puys include 80 volcanoes. The Puy de Dôme is the highest volcano in the region, with an altitude of . The Sancy Massif in the Monts Dore is the highest point in Auvergne at . The northern part is covered in hil ...

Conglomerate (geology)
Conglomerate () is a sedimentary rock made up of rounded gravel-sized pieces of rock surrounded by finer-grained sediments (such as sand, silt, or clay). The larger fragments within conglomerate are called clasts, while the finer sediment surrounding the clasts is called the matrix. The clasts and matrix are typically cemented by calcium carbonate, iron oxide, silica, or hardened clay. Conglomerates form when rounded gravels deposited by water or glaciers become solidified and cemented by pressure over time. They can be found in sedimentary rock sequences of all ages but probably make up less than 1 percent by weight of all sedimentary rocks. They are closely related to sandstones in origin, and exhibit many of the same types of sedimentary structures, such as tabular and trough cross-bedding and graded bedding.Boggs, S.

Ancient Roman Architecture
Ancient Roman architecture adopted the external language of classical ancient Greek architecture for the purposes of the ancient Romans, but was different from Greek buildings, becoming a new architectural style. The two styles are often considered one body of classical architecture. Roman architecture flourished in the Roman Republic and to an even greater extent under the Roman Empire, Empire, when the great majority of surviving buildings were constructed. It used new materials, particularly Roman concrete, and newer technologies such as the arch and the dome to make buildings that were typically strong and well engineered. Large numbers remain in some form across the former empire, sometimes complete and still in use today. Roman architecture covers the period from the establishment of the Roman Republic in 509 BC to about the 4th century AD, after which it becomes reclassified as Late Antique or Byzantine architecture. Few substantial examples survive from before about 100 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
