Can you help make this a better article? What good localities have we missed? Can you supply pictures of better specimens than those we show here? Can you give us more and better information about the specimens from these localities? Can you supply better geological or historical information on these localities?

Here will go a good picture of a calcite specimen from Portugal and general remarks about the calcite from this country. Here are some url's to some of the better Portuguese calcite specimens here on Mindat that can be considered for inclusion in the article. These, in most cases are just for temporary use until we can get images of the much better specimens that are almost certainly out there. We should also consider that there are probably localities out there with fine specimens that are not even mentioned on Mindat. Also in some instances there are sometimes pictures on Mindat, of specimens from a locality, but they were so ratty that I did not include them here, but there may also be really good specimens from there that we should talk about in this article.

Hi again Rock


This locality gives relatively small specimens but in my opinion it should be considered too.

Not "CALICITE, Portugal" but "Calcite, Portugal"

You have already done some work here. Why don't you go ahead and write the article on Portuguese calcites? First you list the localities and possible images you want to use. Then you reverse the locality strings and embed the images in the forum posting box which is exactly the same as this one and the one you made above. Then you tweak the images to make them all nice and orderly looking. Finally you create a header where you discuss Portuguese calcites in general and then below the pictures of each of the Portuguese calcite localities you write what you know about the calcites from those localities. As you go along you will find that you will occasionally want to throw out some of the images you originally selected or add new ones. Often other mindat people will come along and bring your attention to other pictures, localities or information that you may wish to include in the article as well.

I don't know anything about Portuguese calcite localities and that is why it is important for someone like you to write these articles. All I can do in many cases is to select out possible pictures and arrange them nicely and hope that someone who knows more than I do about these localities to come along and tell us about them. I can go searching through the literature and can often find little bits of information about the localities, but that can't compare to having someone who knows the localities from long experience write about them. Often the people who know the stuff we need here in these articles do not have English as their first language and are reluctant to write what needs to be written because they think their English is not good enough. In these cases I or others will be glad to rework the text into a more standard form. Even for people whose first language is English need to have others review their writing and help correct mistakes and make needed changes.

If you run into any problems, I and others will be here to help smooth out the rough spots.

See what I mean that even English speakers need help with their English? What a hoot. Thanks for the correction. Done!

Hi Rui,

You seem to be an expert on Calcite in Portugal. During walks in the Fatima Area I have found some pieces, but none as nice as the ones on this website... Calcite seems to have healing properties, for this reason I would like to send them to people for free (just shipping costs). Do you have any idea where or how I could find nice specimens in the Fatima area? Until now I find them during walks, mainly on hilltops. But probably there are better ways to do it...

Warm regards,
Wim, Fatima
