Izalco (volcano)
Izalco is an active stratovolcano on the side of the Santa Ana Volcano, which is located in western El Salvador. It is situated on the southern flank of the Santa Ana volcano. Izalco erupted almost continuously from 1770 (when it formed) to 1958 earning it the nickname of "Lighthouse of the Pacific", and experienced a flank eruption in 1966. During an eruption in 1926, the village of Matazano was buried and 56 people were killed. The volcano erupted on highly arable land which was used for the production of coffee, cacao, and sugar cane. Geology and mineralogy The lava historically erupted from Izalco consists of Vesicular texture, vesicular Vitrophyre, vitrophyric olivine basalts. Izalco's formation was preceded by fumarole, fumorolic activity in 1658, before Izalco was born in 1770. Today, Izalco experiences only fumarolic activity in the form of rainwater seeping into the volcano and contacting hot rocks, rather than steam emissions from underground gases. The fumarole de ...

El Salvador
El Salvador (; , meaning " The Saviour"), officially the Republic of El Salvador ( es, República de El Salvador), is a country in Central America. It is bordered on the northeast by Honduras, on the northwest by Guatemala, and on the south by the Pacific Ocean. El Salvador's capital and largest city is San Salvador. The country's population in 2022 is estimated to be 6.5 million. Among the Mesoamerican nations that historically controlled the region are the Lenca (after 600 AD), the Mayans, and then the Cuzcatlecs. Archaeological monuments also suggest an early Olmec presence around the first millennium BC. In the beginning of the 16th century, the Spanish Empire conquered the Central American territory, incorporating it into the Viceroyalty of New Spain ruled from Mexico City. However the Viceroyalty of Mexico had little to no influence in the daily affairs of the isthmus, which was colonized in 1524. In 1609, the area was declared the Captaincy General of Guatemala by t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fingerite
Fingerite is a copper vanadate mineral with formula: β-Cu2V2O5. It was discovered as triclinic crystals occurring as volcanic sublimates around fumaroles in the crater of the Izalco Volcano, El Salvador. Associated minerals include thenardite, euchlorine, stoiberite, shcherbinaite, ziesite, bannermanite, chalcocyanite and chalcanthite Chalcanthite (, ) is a richly colored blue-green water-soluble sulfate mineral . It is commonly found in the late-stage oxidation zones of copper deposits. Due to its ready solubility, chalcanthite is more common in arid regions. Chalcanthite i .... The mineral also dissolves in water. Fingerite is named for Dr. Larry W. Finger (b. 1940) of the Geophysical Laboratory, Carnegie Institution of Washington.

It was established through joint agreement between the United States Postal Service and the Smithsonian Institution and opened in 1993. Premises The museum is located across the street from Union Station, in the building that served as the main post office of Washington, D.C. for decades, from its construction in 1914 until 1986. The building was designed by the Graham and Burnham architectural firm, which was led by Ernest Graham following the death of Daniel Burnham in 1912. The headquarters of the United States Department of Labor's Bureau of Labor Statistics is based in this building, and there is also space for a data center for the United States Senate. Displays The museum holds the National Philatelic Collection. It has hosted many interactive displays about the history of the United Stat ...

Francisco Dueñas
Francisco Dueñas Díaz (3 December 1810 – 4 March 1884) was a Salvadoran politician and member of the Conservative Party who served as President of El Salvador on four different occasions: 3 May 1851 to 30 January 1852, 1 February 1852 to 1 February 1854, 1 to 12 February 1856 in acting capacity, and 26 October 1863 to 15 April 1871. He was "an ardent defender of the clerical interests. Dueñas at one time had taken the vows as a Dominican, but when the convents were closed in 1829, he left the cloister and secured a papal dispensation." Under his leadership, "the clerical party was in the ascendancy and El Salvador experienced a far-reaching Conservative reaction."J.

Salvadoran Colón
The colón was the currency of El Salvador from 1892 until 2001, when it was replaced by the U.S. dollar during the presidency of Francisco Flores. The colón was subdivided into 100 centavos and its ISO 4217 code was SVC. The plural is "''colones''" in Spanish and the currency was named after Christopher Columbus, known as ''Cristóbal Colón'' in Spanish. Currency symbol The symbol for the colón is a ''c'' with two slashes. The symbol "₡" has Unicode code point U+20A1, and the decimal representation is 8353. In HTML it can be entered as ₡. The colón sign is not to be confused with the cent sign (¢), which has a code point U+00A2 in Unicode (or 162 in decimal), or with the cedi sign ₵, which has a code point U+20B5 in Unicode (or 8373 in decimal). Nonetheless, the commonly available cent symbol '¢' is frequently used locally to designate the colón in price markings and advertisements.

Ziesite
Ziesite is a copper vanadate mineral with formula: β-Cu2V2O7. It was discovered in 1980 as monoclinic crystals occurring as volcanic sublimates around fumaroles in the crater of the Izalco Volcano, El Salvador. It is named after Emanuel George Zies (1883–1981), an American geochemist who studied Izalco in the 1930s. Closely related is blossite, also a copper vanadate with formula of α-Cu2V2O7. It forms orthorhombic crystals. Blossite was also first described for specimens from the Izalco volcano. Ziesite and blossite are polymorphs, different crystal structure for the same chemical composition and are quite similar in physical properties. Associated minerals include stoiberite, shcherbinaite, bannermanite, fingerite, mcbirneyite, blossite, chalcocyanite and chalcanthite Chalcanthite (, ) is a richly colored blue-green water-soluble sulfate mineral .
