X-ray fluorescence images acquired using the Maia large solid-angle detector array and integrated real-time processor on
the X-ray Fluorescence Microscopy (XFM) beamline at the Australian Synchrotron capture fine detail in complex
natural samples with images beyond 100M pixels. Quantitative methods permit real-time display of deconvoluted
element images and for the acquisition of large area XFM images and 3D datasets for fluorescence tomography and
chemical state (XANES) imaging. This paper outlines the Maia system and analytical methods and describes the use of
the large detector array, with a wide range of X-ray take-off angles, to provide sensitivity to the depth of features, which
is used to provide an imaging depth contrast and to determine the depth of rare precious metal particles in complex
geological samples.
