Illite Fluorescence Microscopy: A New Technique in the Study of Illite in the Merrimelia Formation, Cooper Basin, Australia

Diagenetic history of the Surma Group sandstones (Miocene) in the Surma Basin, Bangladesh

“…The presence of grain coating, hair-like and honeycomb-like crystals with spiny terminations indicate a diagenetic origin Lemon and Cubitt, 2003). Illite which typically forms during progressive burial (mesodiagenetic) through the transformation of infiltered clays (smectites via mixed layer illite-smectite) (Keller et al, 1986;Morad et al, 2000) under high temperatures of 90-130°C requires high K + /H + ratios in pore waters Ehrenberg, 1993;Morad and De Ros, 1994).…”

Giant calcite concretions in aeolian dune sandstones; sedimentological and architectural controls on diagenetic heterogeneity, mid-Cretaceous Iberian Desert System, Spain

“…They show a yellow fluorescence (Fig. llB), similar to illite rims described by Lemon and Cubitt (2003). In addition, clay minerals have been observed coating framework grains under SEM (Figs.…”

Distribution of diagenetic alterations within depositional facies and sequence stratigraphic framework of fluvial sandstones: Evidence from the Petrohan Terrigenous Group, Lower Triassic, NW Bulgaria

“…Mud-rich surface waters, which prevailed during deposition of these floodplain muds, would percolate into underlying channel and crevasse splay sandstones and thus produced ideal conditions for infiltration of clays into the sandstones towards the base of the HST (Ketzer et al, 2003;El-Ghali et al, 2006). The fibrous, hair-like, flaky and honeycomb-like and with spiny terminations and booklet-like habits of illite indicate diagenetic origin Lemon and Cubitt, 2003). Illite, which typically forms during progressive burial (i.e.…”
