OFICARSA QUARRY



In 2002 I saw the first specimens of prehnite from this quarry. I was not told where they were from, but I went to explore until you find the quarry, which was not difficult. The quarry had been working for several years but the prehnite appeared at a certain depth, reaching here had not appeared at all. The first had a good shine but very soft color and development of small crystals, very nice.

 From then went to the quarry almost daily to rescue grinding specimens. So I spent a long time out voids of all the qualities and different shades of green. The very high quality specimens were scarce, although the amount was large. Many specimens of low brightness although some very aesthetic.

Prehnite in situ

This hollow out several specimen

As I said the quarry would almost every day for several years.

 Minerals that I've found are prehnite, pyrite, diopside, titanite, calcite, quartz and amphibole some more type byssolite - actinolite (without analyzing). Regarding diopside, some think it is augite. I have analyzed four different samples by x-ray diffraction, in all four cases the result has been diopside.
