Iron meteorites characteristics
http://meteorite.unm.edu/meteorites/meteorite-museum/how-id-meteorite/ WebIron meteorites (Fig. 1) are almost entirely iron-nickel metal and, because of their durable composition, represent some of the largest known meteorites recovered. Iron meteorites are strongly magnetic and also show a pattern when etched by chemicals due to the iron-nickel minerals that make up their structure (Fig. 2). Figure 2.

WebIron meteorites consist of several distinct Fe-Ni metal phases, which range between 4 and 60 wt% Ni, such that most have between 5 and 20 wt% Ni (reviewed by Mittlefehldt et al., 1998; Grady and Wright, 2003). Alloys consist of domains of various phases, each of which can also have domains. WebIron meteorites are very dense - much heavier than almost all terrestrial rocks - and will easily adhere to a strong magnet. Iron meteorites also contain a relatively high percentage …
WebMany metals are mistaken as meteorites, including: Lodestone, or magnetite, is a naturally occurring iron-rich stone found here on Earth in veins like gold. It responds strongly to a magnet. However, it does not have the high nickel content of an iron meteorite. Slag refers to impure pieces of metal left over from the ore refining WebHere are a few characteristics that suggest a rock might be a meteorite. A rock might be a meteorite if it has these qualities: Fusion Crust Fusion Crust thin black coating Don’t be fooled by black desert varnish common on rocks in desert regions, “skin” on volcanic rocks or artificial slag, or chemical reaction rinds.
