From: Gamma mark: an ingenuity to ease the aiming of melt inclusions in phenocrysts with NanoSIMS
Example of using the \(\Gamma\) mark. a Optical image. Circles surround the melt inclusion and the \(\Gamma\) mark. b Sketch of a melt inclusion and the \(\Gamma\) mark. MI is melt inclusion. A, B, and C are Points A, B, and C, respectively. c Ion image of \(^{19}\)F. The \(\Gamma\) mark is visible, while the melt inclusion is invisible. The area surrounded by the dashed line indicates the position of the melt inclusion, as imagined from the information in the sketch
