Determinación de cloritas en rocas metamórficas de bajo grado mediante propiedades ópticas.
, 2011 [EN] Chlorites are essential rock forming minerals in low and very low grade metapelites. Nevertheless their grain size and thin intergrowths with mica do not allow their optic accurate studies. Therefore determinations based on very simple observations, essentially interference colour and sign of elongation, are proposed, in order to try an approach ...
