doi:10.2204/iodp.proc.304305.203.2009 Data report: characterization of sulfide minerals from gabbroic and ultramafic rocks by electron microscopy1D.J. Miller,2 T. Eisenbach,2 and Z.P. Luo3AbstractThis objective of this research was to investigate the potential of using transmission electron microscopy (TEM) to determine sulfide mineral speciation in gabbroic rocks from Atlantis Massif, the site of Integrated Ocean Drilling Program Expedition 304/305. The method takes advantage of TEM analysis techniques and proved successful in sulfide mineral identification. TEM can provide imaging of the sample morphology, crystal structure through the electron diffraction, and chemical compositional information through X-ray energy dispersive spectroscopy. Electron probe microanalysis was also used to determine the chemical composition. |
