moneditis real deaocho

Meteorito metálico.

Los meteoritos metálicos, también conocidos como sideritos, holosideritos, meteoritos férricos o meteoritos ferrosos, son un tipo de meteoritos que se caracterizan por estar compuestos mayoritariamente por hierro (Fe) y níquel (Ni), sobre todo formando aleaciones llamadas kamacita y taenita.¹² Se cree que son restos del núcleo de asteroides que se destruyeron al impactar entre ellos o con otros cuerpos del Sistema Solar.³ Debido a su gran densidad y tamaño, el peso de todos los meteoritos metálicos recolectados supera las 500 toneladas, lo que representa un 89,3% de la masa total de todos los meteoritos conocidos. Sin embargo, solo representan un 5,7% de las caídas.⁴

Existen dos formas de clasificar a los meteoritos metálicos: una de ellas, la más antigua, se basa en la observación de la estructura del meteorito cuando se corta, se pule y se trata con aguafuerte, y se denomina clasificación estructural;² la otra es la clasificación química, y tiene como criterio la cantidad de elementos traza (germanio [Ge], galio [Ga] o iridio [Ir]) que contiene el ejemplar.²

Por su composición sufren menos ablación al entrar en la atmósfera, lo que hace que su tamaño sea mayor comparado con el de los meteoritos rocosos o los litosideritos.⁴ El meteorito de mayor tamaño que se conoce es el meteorito Hoba, encontrado en Namibia, con un peso de unas 60 toneladas.⁵

https://en.wikipedia.org/wiki/Muonionalusta

The Muonionalusta is a meteorite classified as fine octahedrite, type IVA (Of) which impacted in northern Scandinavia, west of the border between Sweden and Finland, about one million years BCE.

The first fragment of the Muonionalusta was found in 1906 near the village of Kitkiöjärvi.^[1] Around forty pieces are known today, some being quite large. Other fragments have been found in a 25-by-15-kilometre (15.5 mi × 9.3 mi) area in the Pajala district of Norrbotten County, approximately 140 kilometres (87 mi) north of the Arctic Circle.

The meteorite was first described in 1910 by Professor A. G. Högbom, who named it “Muonionalusta”, after a nearby place on the Muonio River. It was studied in 1948 by Professor Nils Göran David Malmqvist.^[2] The Muonionalusta, probably the oldest known meteorite (4.5653 billion years),^[3] marks the first occurrence of stishovite in an iron meteorite.

The name Muonionalusta has Finnish roots and is difficult for some to pronounce: [‘mu-o-ni-on-alu-sta] or /MOO-oh-ne-ohn-ah-loo-stah/ from the Muonio River; -(o)n- signifies a possessive (of Muonio); the final element alusta means ‘base, foundation, a stand, mat, tray’, thus probably ‘base of Muonio (River)’

P.S.II Interesante artículo sobre ciclos económicos largos

“…In the 1500-1600 period the Spanish empire was the pre-eminent economic empire in the “Western” world while the Chinese empire under the Ming Dynasty was the most powerful empire in the “Eastern” world, even more powerful than the Spanish empire (see the green dashed line and the red solid line in chart 2). The Spanish got rich by taking their ships and military power around the world, seizing control of vast areas (13% of the landmass of the earth!) and extracting valuable things from them, most importantly gold and silver which were the money of the time. As shown by the orange line in the chart of the relative standing of the great empires, the Dutch gained power as Spanish power was waning. At the time Spain controlled the small area we now call Holland. When the Dutch became powerful enough in 1581, they overthrew the Spanish and went on to eclipse both the Spanish and the Chinese as the world’s richest empire from around 1625 to their collapse in 1780. The Dutch empire reached its peak around 1650 in what was called the Dutch Golden Age. This period was one of great globalization as ships that could…”

El autor le da demasiada importancia al Imperio Holandés, dando un tanto de lado al Imperio Español. Algo tiene contra nuestros métodos y/o saberes y/u objetivos y/o motivaciones de la época en cuestión 😉
