And changed the lay-out of the article, it's more relaxed for the eye when all the subsequent pics next to each other are the same in height, do you agree?

Harjo, It indeed looks elegant when all the pictures are the same height. However I think that the images should all have captions that have at least the name of the mineral above it as well at the scale. This is especially true if the image has associations. I think it is inconsiderate of us to make the user to go the the trouble to click on the picture to have to go and read the full caption to find out what obvious associations are. Also in the future, I think flags may be attached to each locality section of the articles we are writing so if the user wants to see all the minerals from a particular mine or country, that the search results will take certain parts of our articles and mix them together. Here it would be very helpful if each image had captions of what the minerals were. If the only thing in the captions is the scale, then you have a lot more latitude to adjust the height of the images than if you have to put in more information. I try to make as many of them the same size as possible but sometimes because of the length of the necessary caption I make the image larger than I might normally do. I also sometimes make micro images somewhat smaller than those of larger specimens or especially fine specimens. I also think that mixing up the size of the images will in the long run be more visually stimulating that making them all the same height. Different philosophies lead to different results. There is no reason in what we are doing here that we can't accommodate these to a certain degree.

I just got in some images of the Meilel mine. Mostly locality images but one good millerite image. Ill shortly upload them to Mindat for your consideration.

The Thompson, Manitoba Millerites werre all frozen in Calcite that was etched away with HCl. Thwere also two generations of Millerite there. The second were clumpy xls atop the acicular material. Dave Joyce and Rod Tyson brought them to market. Rod had at least one 45 gallon drum shipped home. No wrapping needed, they were wrapped in Calcite!!! If no one else chimes in I'll talk to them and get more info.

Hi Rob, I added the info about the etching out of the Thompson specimens, thanks!

Harjo

some information on Deep Navigation colliery, feel free to use what you want.

Originally named Harris's Navigation after the Harris Navigation Steam Coal Company's main shareholder (who also gave his name to the village of Treharris), shaft sinking began in 1873. At the time of their completion in 1878, the 760 yards deep south shaft was the deepest in the coalfield.

By 1896 the colliery was owned by Ocean Coal Co. Ltd and named Deep Navigation, at which time it employed 1,846 men and boys, rising to 2328 men at its peak in 1923.

For many years the the pit produced the best quality Welsh steam coal, during the 1980's average annual output reached 375,000.

Deep Navigation closed in 1991, the colliery buildings have been removed and the site extensively landscaped.

cheers

also a historical fact that might be of interest

The Colliery produced high quality steam coal which was greatly in demand notably by Cunard Steamlines. Deep Navigation became the sole source of the coal used for the record-breaking "Blue Ribband" trans-Atlantic crossings of both the SS. Mauretania and the SS Lusitania.

Harjo, I have just uploaded a good picture of a millerite specimen from Casey Jones from the Meikle mine. You may wish to use it.

[www.mindat.org]

I also uploaded 8 images of the collecting site in the mine where the millerite was collected.

Cool piece Rock!
I'll add it right away!

I wish it were in my collection, but it is not. Casey came into my warehouse shortly after he had dug the specimens and showed me a box full of them. Many had not yet been trimmed or cleaned. He knows I collect micros so I picked up one of the larger specimens, turned it upside down and shook it and when nothing fell out, I demanded, where are my micros and shook it some more. He eventually did get me some very nice micros. He didn't have all that many of them and I knew he was going to have to get big money for the good ones, so I decided to settle for some micros, but it is nice to see a bunch of a nice new find like that.

Hi Harjo

just noticed a couple of small errors in the Wales section.

The Coed Ely entry is Mid Glamorgan, not Mis Glamorgan (other Mid Glamorgan entries are OK though).

The second Gelli Colliery picture is incorrectly dimensioned. It is shown as the FOV being 0.4cm, but it quite a bit bigger as the main crystal is itself 1.5cm

regards

I updated the Millerite article. Did I miss anything?

This is a bit late but here is a millerite on blue chalcedony with calcite in an Indiana geode from the Harrodsburg road cuts, Monroe county Indiana. Found as a whole geode and opened in april 2005. I see where a previous poster of this location refers to it as more closely associated with Bedford, Lawrence County Indiana. More correctly, the location is closer to the town of Bloomington Indiana and both the site and town are in Monroe County.

Thanks Bob, very nice!
Could you add it to the database?

Cheers,

Regarding the millerite (with other micros) from Bologna prov. Italy, they are found in hydrothermal veins associated with ophiolites scattered in cretaceous sedimentary layers.

Bob,
That's a very nice millerite and should be in the best millerites, but unless you upload it to our database formally and not just as an attachment to a thread post like you did here, it won't be included.
