Metodología para el estudio de la clorita en rocas metamórficas
8 páginas, 6 figuras, 5 tablas[EN] A methodology based on microscopio and X-ray diffraction studies is proposed, for the cases where the grain size of chlorites do not make available the use of other methods.

Aspectos químicos de la magnetita y clorita de las "ironstones" ordovicicas de Zamora (España)
The chemical characteristics of the magnetites and the chlorites from Ordovician ironstones of Zamora are described in this paper. The unusually Hig contents of Ti, V, Cr. Ba and Ni magnetite indicates, probably, the existence of a basic precursor in the sourceland and Co/Ni ratio

Las cloritas de los cuerpos pegmatíticos del plutón de La Cabrera (Sistema Central Español)
The chlorites included within the pegmatitic bodies of the La Cabrera pluton (Spanish Central System) have been studied in order to stablish their characterization, clasification and relationship with other minerals. Two different chlorite types have been recognized: a) Fe-Mg chlorites (intermediate terms between clinoclore an chamosite), asociated ...

[EN] An empirical method, based on the variation of the ratios between the structure factors of the 004/003 and 004/005 basal reflexions, is proposed. This method takes into account not only presence of heavy atoms but also the chlorite di-trioctahedric character.
