|
|
Best wishes to all. My name is Silvia Esteves, and I am a retired science/math teacher. I took early retirement in 2019 with the hope to do some traveling with my partner, but world events put a stop to that. I have been collecting minerals for about 40 years, but seriously for only about five years.
I hope you will enjoy what I have to offer.
I will start with my minerals from Panasqueira, a mine I hope to visit again.
I welcome all polite criticism and comments, and I will try to post a few pictures every few days.
Mineral: | Ferberite, Muscovite, Quartz and Siderite |
Locality: | Minas da Panasqueira, Aldeia de São Francisco de Assis, Covilhã, Castelo Branco, Cova da Beira, Centro, Portugal | |
|
Dimensions: | 16 cm x 14 cm x 10 cm |
Description: |
This is one of my best Portuguese Ferberite specimens. It contains very lustrous bladed crystals of Ferberite to 12 cm in length. The crystals lie on a Muscovite and Siderite (rear) rich matrix. Crystals of Quartz to 9 cm long are also present. |

Hi Silvia,
welcome to the community, nice to see another new member here. Your first specimen is really fine, also a very good photo! What are your focuses in collecting, any favourite minerals and localities? Besides Panasqueira ;-)
Best regards
Tobi

My partner and I have many specimens from many classic European localities and some from every corner of the globe.
We have 30 specimens from Panasqueira ranging in size from museum to miniature and covering all species from the mine. We have about 300 photos in all related to Panasqueira minerals, as well as over 200 site/region photos some taken by friends and family living in or near Panasqueira. So expect some nice site photos too.
We are very keen on collecting minerals with a theme, hence Panasqueira. We also like
minerals that tell us about the mineralogy/geology of the mine from which they came.
I have always been hesitant about dealing with social media, and for good reasons. Many people told me that FMF was more than just a social media site.

I am very interested in the genesis of minerals within the Panasqueira ore-body, and I have read many scientific papers on the site, some published in late 2020 and early 2021. My partner often says that rocks do speak - you just have to listen. So I will let my Panasqueira speak by showing all aspects of the specimen.
Mineral: | Ferberite, Quartz, Muscovite, Siderite |
Locality: | Minas da Panasqueira, Aldeia de São Francisco de Assis, Covilhã, Castelo Branco, Cova da Beira, Centro, Portugal | |
|
Dimensions: | 16 cm x 14 cm x 10 cm |
Description: |
Large blocky doubly terminated crystals of Ferberite on Muscovite with Quartz. |

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.
