| Abstract: | The initial results of the first dedicated confocal scanning laser microscopy (CSLM) study of fluid inclusions in quartz are presented. CSLM imaging of a large inclusion shows the quartz crystal to contain numerous small (< 1 μm), highly reflective inclusions arranged along planes in at least two directions that are not readily visible in transmitted light. The technique allows measurements to be made of the angular intersection and orientation of the planes in both two and three dimensions. Results suggest that larger inclusions (> 10 μm) occur where two planes of small inclusions intersect, and that the shape of the large inclusions is controlled by the angular relationship between intersecting planes. |
