Heavy mineral analysis is applied to sandstones. The method is applicable to all types of samples including cores,
side wall cores and ditch cuttings. Following disaggregation, the heavy mineral suite is separated from the 63-125um
fraction using heavy liquids. A relatively narrow size fraction is used because this minimises the effects of changes
in grain size on heavy mineral populations.
The following analytical techniques are utilised:
This enables us to determine the relative abundance of all the components of the heavy mineral assemblages and to calculate provenance sensitive heavy mineral ratios.
