Abstract

Fluid inclusions are naturally formed micro-containers in minerals that have been sealed since the mineral was formed. Analysis of inorganic and organic fluids from various inclusions is of particular interest for geologists, who are investigating environmental information and sometimes organic content. The inclusions are to a large extent prevented from contamination and many temporal changes as they are embedded within minerals. However, an essential part of the investigation procedure is the method of extracting fluids from such minerals. Since mechanical drilling or polishing involves a high risk for contamination of the sample, it is suggested to use a laser ablation technique to isolate the samples. In order to assess the potential of this technique, we have studied the parameters for laser ablation in quartz, calcite and apatite (the most common minerals containing fluid inclusions).
