We offer sample descriptions at a range of level of detail, from summary descriptions focussed on a specific set of feature(s) in a sample or sample set, up to completely-comprehensive characterisation of all aspects of the sample.
Most of the descriptive work is carried out using optical (plane-polarised light) light microscopy. However, additional detail will usually be added using scanning electron microscopy and other microscopy methods as required. Any additional micrcoscopy observations are incorporated directly into the sample descriptions (and not presented as separate descriptions).
There is always a temptation to “scrimp-and-save” a little on this aspect of petrographical studies, but this is the time where the real detail and intricacies of samples can be investigated and documented.
