In order to mimic the pH present in pore solutions of CSA cements, 0.1 g KOH / 100 g CSA were introduced into the system. As in ACF diagrams, tielines connect minerals which coexist in equilibrium. solid ratio of 1 in steps of 2 mass- for the whole ternary diagram C 4 A 3 S -C 2 S-CS assuming complete hydration. The minerals quartz and albite are assumed to be present in the rocks and are not shown on the diagram.
Each of these components has to be modified slightly to account for the presence of other, minor components in the rock, leading to: A (Al 2O 3 - 3K 2O) F (FeO - TiO 2 - Fe 2O 3) and M (MgO). The components of the diagram are thus A (Al 2O 3), F (FeO), and M (MgO), with the projection geometry being accommodated on specially scaled axes.
AFM TERNARY DIAGRAM DOWNLOAD
Mineral and rock compositions plotting within this diagram are projected on to the Al 2O 3-FeO-MgO face from either the muscovite or K-feldspar point on the Al 2O 3-FeO edge. Download scientific diagram Variation diagrams (a) AFM ternary diagram (AZNa 2 OCK 2 O, FZFeO t, MZMgO) compositional variation line after Irvine and. The three components plotted on AFM diagrams are derived from a tetragonal diagram, with species Al 2O 3, K 2O, FeO, and MgO, and are ideal for showing mineral assemblage variations as a function of the composition of pelites.
AFM TERNARY DIAGRAM UPDATE
The Link the chart to the input data option can be used to update the diagram in real time when the input data is modified. Besides SiO 2, the five most abundant oxides found in metamorphic rocks are Al 2O 3, CaO, FeO, MgO, and K 2O. Ternary Diagrams are a visualization method that is particularly useful in domains where one works with three elements with varying proportions, for example in chemistry or petrology. A three-component, triangular graph used to show how metamorphic mineral assemblages vary as a function of rock composition within one metamorphic facies.
