+    Foam::pureZoneMixture
+
+Description
+    Version of pureMixture that uses different mixtures for different
+    cellZones.
+    Every cellZone has to provide an entry for its mixture. A reserved
+    entry 'none' is for all unzoned cells.
+
+    Example of the zone based mixture specification:
+    \verbatim
+    mixture
+    {
+        solid1
+        {
+            specie
+            {
+                molWeight   50;
+            }
+
+            transport
+            {
+                kappa   80;
+            }
+
+            thermodynamics
+            {
+                Hf      0;
+                Cp      450;
+            }
+
+            equationOfState
+            {
+                rho     8000;
+            }
+        }
+        solid2
+        {
+            //- Start off from 'solid1' properties
+            ${solid1}
+
+            //- Selectively overwrite properties
+            transport
+            {
