TESCAN Integrated Mineral Analyser (TIMA) images of samples from Mindola North, and Nchanga, Zambia

TIMA images of samples from Mindola North, and Nchanga. TIMA images at Nchanga include Mindola Clastics and Upper and Lower orebodies. Identified minerals include quartz, microcline, phlogopite, muscovite, dolomite, chlorite, albite, calcite, chalcopyrite, carrollite, bornite, Co-pyrite, chalcocite, malachite and heterogenite. TIMA images from Mindola show dolomitic siltstones and impure dolostones. Chapters 4 and 5.

Statement
The samples are first scanned in BSE mode before each of the four EDX detectors takes spectra measurements on each individual pixel. The 4 EDX detectors are operated at very highcount rates and can analyse uneven surfaces with an imperfect polish. The spectra and BSE response can then be compared to a mineral database and classified according to a segmentation algorithm and set of rules defining compositional limits for each phase. Once classified, a fully rasterised image of individual phases can be exported for sample navigation and publication. TESCAN TIMA© uses 4 EDX silicon drift detectors attached to the TESCAN MIRA platform. Full details of the procedure for analysis and modes of operation are found in Hrstka et al., (2018)."
