阴极发光技术发展历史
Already thirty years ago Dr.Marshall has built and sold Cathodoluminescence (CL) equipment in the U.S.A. and Great Britain. I was among the first who be-came interested in CL research for minerals and gemstones in Austria and bought such an instrument 1984. Then, it was called “Luminoscope”. Today it is named ”Reliotron”. To investigate minerals, I had to use a large compartment that could house samples up to 6 x 3.5 x 3 cm placed on an easily moveable sledge. This instrument I have still in use and it is in good working order.

原位稳定同位素对成岩流体行为的影响
Detailed characterization of diagenetic fluid behaviour and evolution is commonly hindered by shortage of appropriate and economic methods to carry out in situ analysis in the tiny diagenetic mineral crystals. Using micromill sampling method, this study presents in situ stable isotopic data for the growth zones of saddle dolomite crystals in the hydrothermally-altered dolostones of Upper Cambrian (Furongian) at Keping, Tarim Basin, NW China. These data show minor and large variations in δ13C (−0.7‰ to −1.5‰ VPDB) and δ18O (−8.3‰ to −13.8‰ VPDB), respectively, from the cores to outer rims of the dolomite crystals and suggest that saddle dolomites precipitated from dolomitizing fluids with similar carbon sources but oscillatory temperatures during different formation stages. This scenario is confirmed by microthermometry of fluid inclusions within the growth zones of dolomite crystals. This study indicates that in situ isotope analysis could provide more detailed information related to the source and pathway of dolomitizing fluids, facilitating better characterization of dolomitizing fluids and processes.
