The Summary screen is designed to give you an overview of your data set and is by default the first screen you will see when you open or create a new TSG data file. It is particularly useful for gauging the degree and type of variability within large data sets. This screen consists of two sub-screens, the Assemblage Histogram (upper) and the Feature Frequency Chart (lower). 

The Assemblage Histogram is driven by the automated spectral analysis program called The Spectral Assistant (TSA v 5.0) which is built into TSG. It is designed to give you an overview of the mineral species or classes likely to be present in your data set. It can be a useful indication of the assemblages or suites of minerals present (eg. phyllic, propylitic, argillic, felsic, mafic, ultramafic, etc.), before launching into the detail analysis of a large number of individual spectra.

The lower half of the Summary Screen is dedicated to the Feature Frequency Chart. With experience users often start to see that certain projects, styles of mineralisation and geologic environments tend to produce their own type of pattern on the Feature Frequency Chart. In a way it's a little bit like a finger print for a data set. These patterns can be used to quickly recognise potentially important changes in lithology, alteration or regolith conditions in project areas.
