| We interpret these grains as xenocrysts from an older source terrain from which the granitic protolith of sample MS 3 may have been derived by anatectic melting. |
|
| In terms of protolith identification, many existing interpretations of the Langavat Belt do not fully consider the intense, multiphase deformation that it has suffered. |
|
| The original rock, known as the protolith, transforms into other mineral types or other forms of the same minerals, by recrystallization. |
|
| If the protolith is siliceous carbonate, then calc-silicate minerals will be part of the mineral paragenesis. |
|
| Weathering and alteration of a harzburgite protolith has produced a type A nickel-laterite deposit up to 17 metres thick. |
|
| The protolith for the Scourian gneisses are thought to be granitic, with subsidiary mafic and ultramafic plutonic rocks giving an overall bimodal character. |
