Malvizza Mud Volcanoes
The Malvizza mud volcanoes are the largest array of mud volcanoes in the southern Apennines of Italy. The phenomenon is purely sedimentary in nature, in contrast to volcanic phenomena like mofette, fumaroles, and solfatare. The Malvizza mud volcanoes show some affinities with the ''salse'' (saltwater springs) of the central-northern Apennines and with the ''maccalube'' (mud fountains) of Sicily. Location and description The Malvizza mud volcanoes (from , the name of a bird in the Irpinia dialect) are located in the Campania Apennines, in the municipal territory of Montecalvo Irpino, along a plateau of the Miscano valley at an altitude of above sea level. They are characterized by the emission of gaseous hydrocarbons—primarily methane, which at most sites accounts for more than 90% of emissions—as well as a continuous flow of weakly alkaline water (pH = 8) at a temperature of . The solid component of the mud is composed of more than 95% illitic clay, with only traces of calci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Apennine Mountains
The Apennines or Apennine Mountains (; grc-gre, links=no, Ἀπέννινα ὄρη or Ἀπέννινον ὄρος; la, Appenninus or – a singular with plural meaning;''Apenninus'' (Greek or ) has the form of an adjective, which would be segmented ''Apenn-inus'', often used with nouns such as ("mountain") or Greek (), but ''Apenninus'' is just as often used alone as a noun. The ancient Greeks and Romans typically but not always used "mountain" in the singular to mean one or a range; thus, "the Apennine mountain" refers to the entire chain and is translated "the Apennine mountains". The ending can vary also by gender depending on the noun modified. The Italian singular refers to one of the constituent chains rather than to a single mountain, and the Italian plural refers to multiple chains rather than to multiple mountains. it, Appennini ) are a mountain range consisting of parallel smaller chains extending along the length of peninsular Italy.

Mofetta
Mofetta ( Italian from Latin ''mephītis'', a pestilential exhalation) is a name applied to a volcanic discharge consisting chiefly of carbon dioxide, often associated with other vapours, representing the final phase of volcanic activity. The Oxford Dictionary of English lists ''mofetta'' as an archaic term for the modern word fumarole. The word is used in the plural as ''mofette'', or, following the French fashion, ''mofettes''. The volcanic vents yielding the emanations are themselves called mofette. They are not uncommon in Auvergne and in the Eifel, notably on the shore of the Laacher See; whilst other examples are furnished by the Grotta del Cane, near Pozzuoli, the Valley of Death in Java, the Death Gulch in the Yellowstone Park and the series of mofette in Romania's Harghita and Covasna counties. Depending on the mineral content of the different vapours, mofette may be used for therapeutic purposes as well. As carbon dioxide is heavier than the air, patients c ...

Fumarole
A fumarole (or fumerole) is a vent in the surface of the Earth or other rocky planet from which hot volcanic gases and vapors are emitted, without any accompanying liquids or solids. Fumaroles are characteristic of the late stages of volcanic activity, but fumarole activity can also precede a volcanic eruption and has been used for eruption prediction. Most fumaroles die down within a few days or weeks of the end of an eruption, but a few are persistent, lasting for decades or longer. An area containing fumaroles is known as a fumarole field. The predominant vapor emitted by fumaroles is steam, formed by the circulation of groundwater through heated rock. This is typically accompanied by volcanic gases given off by magma cooling deep below the surface. These volcanic gases include sulfur compounds, such as various sulfur oxides and hydrogen sulfide, and sometimes hydrogen chloride, hydrogen fluoride, and other gases. A fumarole that emits significant sulfur compounds is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Irpinian Dialect
The Irpinian dialect, or Irpino, is the dialect of Neapolitan language spoken in almost all of the comuni in the Province of Avellino in the Italian region of Campania. It differs from other varieties in certain phrases, pronunciation and the use of definite articles. The dialect is heavily influenced by its geographical neighbours. For example, in the northern area of Avellino, there are some undertones of the Beneventan dialect; and the Arianese dialect, spoken in Ariano Irpino Ariano Irpino (formerly Ariano di Puglia or simply Ariano) is an Italian city and municipality in the province of Avellino, in the Campania region.

Alkali
In chemistry, an alkali (; from ar, القلوي, al-qaly, lit=ashes of the saltwort) is a basic, ionic salt of an alkali metal or an alkaline earth metal. An alkali can also be defined as a base that dissolves in water. A solution of a soluble base has a pH greater than 7.0. The adjective alkaline, and less often, alkalescent, is commonly used in English as a synonym for basic, especially for bases soluble in water. This broad use of the term is likely to have come about because alkalis were the first bases known to obey the Arrhenius definition of a base, and they are still among the most common bases. Etymology The word "alkali" is derived from Arabic ''al qalīy'' (or ''alkali''), meaning ''the calcined ashes'' (see calcination), referring to the original source of alkaline substances. A water-extract of burned plant ashes, called potash and composed mostly of potassium carbonate, was mildly basic. After heating this substance with calcium hydroxide (''slaked ...

Breccia
Breccia () is a rock composed of large angular broken fragments of minerals or rocks cemented together by a fine-grained matrix. The word has its origins in the Italian language, in which it means "rubble". A breccia may have a variety of different origins, as indicated by the named types including sedimentary breccia, tectonic breccia, igneous breccia, impact breccia, and hydrothermal breccia. A megabreccia is a breccia composed of very large rock fragments, sometimes kilometers across, which can be formed by landslides, impact events, or caldera collapse. Types Breccia is composed of coarse rock fragments held together by cement or a fine-grained matrix. Like conglomerate, breccia contains at least 30 percent of gravel-sized particles (particles over 2mm in size), but it is distinguished from conglomerate because the rock fragments have sharp edges that have not been worn down. These indicate that the gravel was deposited very close to its source area, since other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
