Fractured quartz
WebIf quartz was broken during the growth process, it can "reheal," but pressures may also cause fractures within a crystal. When held in sunlight, a "rainbow effect" is produced in the area of a fracture. The nature of the colors depends on the thickness of the space in the fracture (Pictured left: clear quartz with rainbow fracture). ... WebMar 17, 2024 · The in situ fractured quartz is always with much greater fracture density, smaller individual fractures, and apparently random fracture orientation compared with those by the thermal shock. Such in situ fractures rarely penetrate the quartz deeper than 1.0-1.5 mm and therefore present no difficulties in the following sample preparation . The …
