This is a section of one of the Rock Symbols pages, showing how we add annotations and links to the data. The buttons will show actual pictures of rocks and their chart representation, or samples of rock symbols on various charts.
Throughout the Symbols Pages, whenever
there is a cross reference to a related materials — as is the
link shown here to depth references in Section H — we have
made them active with a green shield. Click any of these and
you go straight to the section that is referenced.
