Guarello Island
Guarello Island (Spanish: ''Isla Guarello'') is an island in Madre de Dios Island, Madre de Dios Archipelago in Magallanes Region. Guarello Island is in a limestone area that also includes Madre de Dios Island. The island has the world's southernmost limestone mine and it has reserves for 100 years, and 600,000 tons of limestone with a millesimal fineness of 96% of Calcium carbonate are extracted each year.

Smyth Channel
Smyth Channel () is a principal Patagonia channel (geography), channel. Its south arm is the southward continuation of the Sarmiento Channel and is located in Magallanes y Antártica Chilena Region. The Alacaluf people, Kawésqar people lived along its coast for thousands of years. Its north entrance is in the Nelson Strait (Chile), Nelson Strait at , between Charlton Cape and the western extreme of the Lobos Islands; and its southern terminus is at , between Phillip Cape at the southern extreme of Manuel Rodriguez Island and Merino Peninsula on the mainland, where it opens into the Strait of Magellan. The channel has a length of approximately 96 nmi and is divided into two arms: the northwest arm, which is scarcely used as navigation route and is 50 nmi long, and the south arm (46 nmi long), which is a major waterway for commercial sailing and that stretches from its connection with the Sarmiento Channel at southern tip of the Victoria Pass until the point already named, where i ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ...

United States Hydrographic Office
The United States Hydrographic Office prepared and published maps, charts, and nautical books required in navigation. The office was established by an act of 21 June 1866 as part of the Bureau of Navigation, Department of the Navy. It was transferred to the Department of Defense on 10 August 1949. The office was abolished on 10 July 1962, replaced by the Naval Oceanographic Office. Objectives Before the hydrographic office was established in 1866, U.S. navigators were almost entirely dependent on British charts. A few private enterprises had prepared and published charts, but had not been able to do so profitably. The Hydrographic Office was established "for the improvement of the means for navigating safely the vessels of the Navy and of the mercantile marine, by providing, under the authority of the Secretary of the Navy, accurate and cheap nautical charts, sailing directions, navigators and manuals of instructions for the use of all vessels of the United States, and for the ben ...

Huachipato, Chile
Huachipato is census district and neighbourhood in Talcahuano Commune, part of the conurbation of Greater Concepción in the Biobío Region of southern Chile., United States National Geospatial-Intelligence Agency It is the industrialized part of the commune supporting a steel mill and oil refinery. Etymology The word ''huachipato'' is a Mapuche word meaning "a trap to catch birds". It may be the result of a mixture of Spanish and Mapuche, where the local name for a snare is ''huache'' or ''huachi''. Demographics The district is completely urban and had a population of 9,665 as of the 2002 census with 2,415 housing units.

Steel Mill
A steel mill or steelworks is an industrial plant for the manufacture of steel. It may be an integrated steel works carrying out all steps of steelmaking from smelting iron ore to rolled product, but may also be a plant where steel semi-finished casting products are made from molten pig iron or from scrap. History Since the invention of the Bessemer process, steel mills have replaced ironworks, based on puddling or fining methods. New ways to produce steel appeared later: from scrap melted in an electric arc furnace and, more recently, from direct reduced iron processes. In the late 19th and early 20th centuries the world's largest steel mill was the Barrow Hematite Steel Company steelworks located in Barrow-in-Furness, United Kingdom. Today, the world's largest steel mill is in Gwangyang, South Korea. [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Millesimal Fineness
The fineness of a precious metal object (coin, bar, jewelry, etc.) represents the weight of ''fine metal'' therein, in proportion to the total weight which includes alloying base metals and any impurities. Alloy metals are added to increase hardness and durability of coins and jewelry, alter colors, decrease the cost per weight, or avoid the cost of high-purity refinement. For example, copper is added to the precious metal silver to make a more durable alloy for use in coins, housewares and jewelry. Coin silver, which was used for making silver coins in the past, contains 90% silver and 10% copper, by mass. Sterling silver contains 92.5% silver and 7.5% of other metals, usually copper, by mass. Various ways of expressing fineness have been used and two remain in common use: ''millesimal fineness'' expressed in units of parts per 1,000 and '' karats'' or ''carats'' used only for gold. Karats measure the parts per 24, so that 18 karat = = 75% and 24 karat gold is considered 100% g ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Madre De Dios Island
Madre de Dios Island (Spanish: ''Isla Madre de Dios'', ) is an uninhabited island in the Magallanes Region, Chile. It is located west of the Trinidad Channel and Concepción Channel. Madre de Dios Island is composed partly of limestone and has several natural caves. In one of those caves, called the "Cave of the Whales", skeletons of whales 2600 to 3500 years old have been discovered 10 to 30 meters above sea level. In another cave, named Cueva del Pacifico, rock art was discovered in 2006. Many other caves near the coast were used by the indigenous Kaweskar people for burial. One skull found dates back to 4500 years ago. Some caves were used as temporary camps. The island, along with 53 smaller nearby islands, was protected as a nature reserve (''Bien Nacional Protegido'') in 2007. The island obtained its current name from a map in Alonso de Ovalle's work ''Histórica relación del reino de Chile'' which was published in 1646 in Italy. Apparently Alonso de Ovalle had base ...

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Communes Of Chile
A commune ( es, comuna, ) is the smallest administrative subdivision in Chile. It may contain cities, towns, villages, hamlets as well as rural areas. In highly populated areas, such as Santiago, Valparaíso and Concepción, a conurbation may be broken into several communes. In sparsely populated areas, conversely, a commune may cover a substantial rural area together with several settled areas which could range from hamlets to towns or cities. The term "commune" is ambiguous in English, but the word is commonly used in translation for "comuna", although with some controversy among translators. A comuna is similar to a "county" in Anglo-American usage and practice, and may be more universally understood as a "municipality". Each commune or municipality is governed by a directly elected body known as a municipal council (''concejo municipal'') consisting of a mayor (''alcalde'') and a group of councillors (''concejales''), for a period of four years. The communal civil service a ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
