There appears to be a preference for the name 'Xinjiang' in the Chinese literature, but the name 'Armanty' was adapted in Western scientific literature so that both synonyms appear in the literature today. If we are to use strict geological definitions it should be noted that since they have been altered by heat and pressure, impactites are a type of metamorphic rock.
Catastrophic impacts literally transform surface material into new rock types. The three main classes of meteorites can be separated into more specific meteorite rock types depending on their specific mineral composition, structure, and chemistry. They also contain some metal nickel and iron. Stony Meteorites Stony meteorites are made up of minerals that contain silicates material made of silicon and oxygen. Both the larger mass and the Ulasitai mass are marked by very distinctive siderophile abundances making Xinjiang (Armanty) members of the very small group of IIIE irons with only 15 membersĪt the official website for the Meteoritical Society, the name "Ulasitai meteorite" was discredited as a proper (unique) name once Ulasitai was shown to be paired with the Xinjiang (Armanty) iron meteorite. Meteorites of sufficient size and mass impacting upon the earth’s surface can have a similar effect. Scientists have divided these meteorites into three main types: stony, iron, and stony-iron. The fragments left of the space rock show that it was an iron meteorite. Iron meteorites are enriched with elemental iron alloyed with nickel. STONE METEORITES are the most common and consist of nonmetal stone. The impact blasted a hole 1 kilometer (.6 miles) wide and about 230 meters (750 feet) deep. Ancient Space Debris Stony meteorites are rich in silicate minerals. Meteorites contain rock and minerals which can help us understand our planet, solar system and even life itself. In this exercise I have broken down the Stony. Ulasitai is a fragment of the enormous 20 ton Xinjiang (Armanty) iron which had been previously discovered about 130 km away. There, more than 50,000 years ago, a meteorite weighing about 270,000 metric tons (300,000 tons) slammed into the Earth with the force of 2.5 million tons of TNT. From the point of view of origin, there are three basic types of meteorites: Stony, Stony-Iron, and Iron. Catastrophic impacts literally transform surface material into new rock types. Schreibersite is the most abundant of the minor phases which also include troilite, cohenite, and daubréelite. Meteorites of sufficient size and mass impacting upon the earth’s surface can have a similar effect. The Ulasitai meteoritical mass consists mainly of kamacite (76 vol%) accompanied by taenite (10 vol%) and plessite (~10 vol%).
