The last couple of days I spent some time reviewing photos of the earliest specimens in my collection. Most were photographed about15 years ago, and many do not measure up to today's standards, so I am gradually replacing them with better images. Photos of the last two specimens are the results of this effort as will be the following few.


183 Fluorite - Xianghualing Mine, Linwu Co., Hunan Prov., China.jpg
 Mineral: Fluorite
 Locality:
Xianghualing Mine, Xianghualing Sn-polymetallic ore field, Linwu, Chenzhou Prefecture, Hunan Province, China
 Dimensions: 6.6 x 7.3 cm
 Description:
Two blue-gray octahedral fluorite crystals to 5.6 cm on edge with flattened rhombs of colorless calcite. The fluorite has a frosted luster resulting from tiny stepped faces and the interior contains a green core.

I have been interested in minerals from Romania for the past 30 years, and one of my largest sub-collections is minerals from the Maramures region in northwest Romania. In Tucson this year, I was delighted to find several Romanian specimens to add to my collection. One of the FMF members will no doubt recognize the piece shown below as it was once part of his collection. I hope he is happy it went to a good home.

 Mineral: Calcite
 Locality:
Herja Mine, Chiuzbaia, Baia Mare, Maramures, Romania
 Dimensions: 5.3 x 9.0 x 11.2 cm
 Description:
Creamy white to pale tan elongated calcite crystals. The bottom of the specimen consists of black sphalerite and brassy pyrite.
 Viewed:  703 Time(s)

It is an honor that you can enjoy this piece of Romania, as I have enjoyed it, in the last 18 years.

Thanks Tobi. The mines in this district exploit skarn type deposits and minerals from the Ocna de Fier area are much less common that those from Maramures. The specimen is from a European collection and I was delighted to find it this year in Tucson.

Interesting sample of "flos ferri" aragonite from a classic locality: The Neuhoffnung (or: Neue Hoffnung) Mine belongs to the famous Mercur Mine - one of the main sources of the famous "barrel shape" Bad Ems pyromorphite classics :-)
