![]() ![]() ![]() The presence of magnetite is consistent with the black inclusions' attraction to a magnet, as well as testing with a vibrating sample magnetometer, which provided a ferromagnetic response. Scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS) analysis of the magnetite showed that it is composed of very thin plates containing only Fe and O, without any Ti. The inclusions causing the aventurescence were identified as hematite, while lattice patterns were found to consist of orangey brown platelets of hematite and black platelets of magnetite (rather than ilmenite, as previously reported).

HIGH GRADE RAINBOW LATTICE SUNSTONE OLD STOCK CRYSTAL 1987 10. Electron microprobe and X-ray diffraction (XRD) analysis, combined with laser Raman spectroscopy, indicate the host mineral is orthoclase (), as previously reported in the literature. Rainbow lattice Sunstone rough 31.78 (155424778981) 3s (31) - Feedback left by buyer 3s (31). Abstract : Rainbow lattice sunstone from the Harts Range, Northern Territory, Australia, shows a rare combination of phenomena including aventurescence, adularescence and a distinctive lattice pattern caused by oriented inclusions. ![]()
