Many fluid inclusions contain substantial amounts of CO is very useful in mineral exploration as mineral deposits, such as gold, are frequently associated with such CO 2 rich hydrothermal fluids. If the internal pressure of the inclusion is high enough (above about 50 bars), CO 2 can be present as a liquid phase at room temperatures (below 31 C), as seen in this image.
