Elemental mapping uses the EDS to determine the elemental content of each pixel in a field of view. A false color map is made for each element, showing the relative abundance of the element across the field of view. Blue is the lowest abundance and red / pink represents the highest abundance.
This sample is a fragment of an Esquel Palasite — a stony iron meteorite. This field of view contains three main areas of distinct minerals, with differing ratios of iron (Fe), nickel (Ni) and phosphorus (P). This is an interesting sample as these minerals rarely if ever occur naturally on earth.
