Afm Schematic Diagram. The three components plotted on afm diagrams are derived from a tetragonal diagram with species al 2 o 3 k 2 o feo and mgo and are ideal for showing mineral assemblage variations as a function of the composition of pelites. Atomic force microscopy afm is a type of scanning probe microscopy spm with demonstrated resolution on the order of fractions of a nanometer more than 1000 times better than the optical diffraction limit the information is gathered by feeling or touching the surface with a mechanical probe.
Afm diagram with some common pelitic minerals plotted. Piezoelectric elements that facilitate tiny but accurate and precise movements on electronic. The afm diagram a ternary diagram between the alkali fe and mg oxides used to distinguish the calc alkaline magma series from the tholeiitic magma series.

After irvine and baragar 1971. Most of the time petrologists prefer to find some way to reduce the number of components to three so that triangular diagrams may be used.
