Hola a todos los foreros…
Mirando la web de Mindat.org me he encontrado en el foro
esto sobre las allanitas de Burguillos y las fotos que aparecen en dicho enlace;
¿alguien puede traducirme esto?…lo he intentado con algún traductor de internet
y la verdad que quedan muchas cosas por traducir y mŕs que saber que quiere
decir el texto tengo que intuir….
Dear friends!
Visit on the allanite-(La) photo gallery [www.mindat.org/gallery.php] leave very strange impression of quiet idiocy...
All material from Burguillos really is composed by large crystals of epidote
with very thin zones (~10-50 mkm) of allanite-(La). Summary REE2O3 content of
brutto crystal from here don't exeed 1-2 wt%. Real allanites begin from 6-7 wt.
% of REE2O3 - this are low-REE or calcian allanites.
Moreover allanite-(La) zones concentrated in core parts of epidote crystals and
are INVISIBLE on photos.
It is simply ridiculous to read captions "Allanite- La. 35x33 mm", "A
single Allanite-(La) crystal with small Magnetite crystals, all on a matrix of
Hedenbergite. The upper tip of the crystal was broken and has then
recrystallized ... Main crystal size: 0.9 x 0.5 cm", "Crystal size is 7mm", "Crystal with 1cm on top", etc. All these
words belong to usual green epidote.
It would be ridiculous, if it wasn't sad.
All these captions should be improved. It is possible to speak about
allanite-(La) from Burguillos only concerning with polish sections opening
central parts of crystals or microprobe preparates photos. It is the same as to
show a cow photo and to give the caption "milk".
