Hey everyone.
I'm in doubt if those classification terms (such as phaneritic and leococratic) can still be used to describe a rock that has preserved it's original igneous textures after been affected by a metamorphic event.
Dear Mr. de Bem,
you can use these terms if you can still recognize the characteristic features at outcrop or in the hand specimen.
Leucocratic means ligh-colored impoverished in mafic Fe-Mg minerals. If you find true magmatic rocks showing all the hallmarks of a rock of the granite clan and denominated with the term meta- then you can use this term. The same hold true for phaneritic which is synonymous with "macroscopically crystallized mineral association". I guess that in most very-low-grade to low-grade stage metamorphic rock sections you can still go on using technical terms like those.
I wish you much success
