Hello Silvia,
Very nice Panasqueira specimens and great photos. Thank you for sharing these.
When posting photos to your collection page you can include up to 15 photos in the same post instead of posting each of them separately. This keeps the topic box of newest posts on the right hand portion of the page from being filled up by by one user. After including your photo and entering the required information, just press the preview button and you will be able to attach another photo. When you are done you can then submit the entire post.
Michael

Hello:
I hope I have not caused a problem. I will try to add the photos as a group, but sometimes, in fact often times, after loading a photo I decide to take another a day or two later.
As I am interested in how a mineral forms within the Panasqueira ore-body, in fact all ore bodies, this requires that I take photos of a mineral from several views and a few photos taken as close-ups. These might be taken after I have already loaded a picture.
I will upload a few photos showing the mineralization within the Panasqueira ore body. My partner and I have friends in Panasqueira, and some work for Almonty,, and they have supplied some wonderful site photos - gems in fact.
I hope you understand.

Specimen contains translucent Fluorapatite crystals to 30mm on a Muscovite crystal matrix with a 70 mm long glassy gem Quartz crystal. The specimen is also rich in crystallized Sphalerite and small Siderite crystals. Many of the Siderite crystals contain spherical cores of a sulphide mineral (Pyrite/Pyrrhotite/Marcasite ??) The Fluorapatite crystals display bright orange fluorescence under UVA light.

Book on Panasqueira
One of the projects my partner and I are keen to do is self-publish a book on the Panasqueira Mine. It will be well documented, professionally illustrated and available to all free-of-charge as a download from our webpage - a living legacy to our children.
The book will cover many topics, including but not limited to past and present mining methods, geology, geography, historical personalities, and of course our Panasqueira mineral collection.
Thanks to family and friends, and the help of Almonty we have some wonderful pictures to show.

We do have a copy of the publication. The earliest article we have on Panasqueira is 1925. We are trying to find any persons related to the Mine Managers of the early 1900's. It is amazing what some people have lurking inside dusty boxes in the basement or attic of their homes.
We have also read the wonderful articles published in MinRec and Lapis about the minerals from the Panasqueira mine.Lots of Fluoroapatite pictures :)
The diversity of minerals within the Panasqueira ore body makes it a fabulous site to study, and of course there is a lot of social history too.We are proud to have many of the main collector quality minerals from the site, and we are adding more to our collection.
I have attached as a jpeg a summary of the minerals we have obtained from the Panasqueira ore body, and it is based on a table published in a 1963 publication by Beralt Tin and Wolfram Ltd entitled, Couto Mineiro Da Panasqueira, Treatment of Ore, May 1963.

The specimen contains many gem colourless crystals of Quartz, the most prominent crystal is 9 cm long. Bright lustrous crystals of Arsenopyrite to 3 cm are also present as well as 'spherical' crystals of an unknown mineral, perhaps chlorite (?).

What a gorgeous Panasqueira specimen! Very impressive size and great aesthetics with that paragenesis. A true museum piece, wow!

Bravo, this is wasn't easy, and yes, it is Chlorite (probably Clinochlore but impossible to be sure without analysis, so, Chlorite Group
BTW, you can add the Chlorite (Group) to your 'Panasqueira Collector Minerals' list, because some times it appears as fine specimens. Also, the elusive Panasqueiraite which very rarely appear as a collector piece, but although very rare is not impossible. This is not the case of the Thadeuite which is mostly intergrowth with the Panasqueiraite.
Be careful with the common triplite, which is frequently named as Panasqueiraite by mistake or by lack of a proper analysis.
Highly recommended too is the article "The Panasqueira mines, Castelo Branco district, Portugal" published by the magazine Mineralogical Record, January-February 2014, Volume 45, Number 1, pages 11-55, because is even more extended than the Bocamina and Lapis ones.

Thank you Tobi, my partner and I appreciate your support. It is not the largest specimen from Panasqueira in our collection. We have a large Arsenopyrite with Sphalerite and minor Muscovite and Siderite.
