摘要
Detailed research with CL and EPMA on carbonate minerals shows that CL intensity on carbonate mineral is related with trace element contents and EPMA beam current, the CL image is correspondent with EPMA element distributing mapping: Calcite CL intensity is related with Mn contents and in less beam current Mn rich areas will emit stronger CL but in larger beam current with cloudy CL image because the exists of Fe that will decrease the CL intensity. The dolomite has a distinctively inner CL image with sometimes showing dolomite rings in less beam current, but with larger beam current the inner CL difference of dolomites disappeared, the CL intensity of dolomites are apparently related with Mn, Fe trace element mapping of EPMA and CL can gives more detail of the carbonate minerals. The CL and EPMA technique can be useful in carbonate reservoir texture, cement sequence and pore evolution analysis.
