Nice idea going on it's main mineral, or most mines will be mixture.
Ganister was worked in it's own right in the UK with coal being taken as the secondary mineral, but I'm ok classing fireclay and ganister as coal mines.
What about when say a mine originally worked one mineral (eg lead) then closed and was re-opened and worked for another mineral (eg fluorite) happened quite alot in Peak District lead mines.
Do we classify on the original working or the most productivity? or something else?
It's getting very difficult to decide how best to approach this :)
I want the site to be as user friendly as possible, but it needs to appeal to people with a good knowledge of minerals and/or mines as well as be accessible to people without that knowledge or just starting out. I don't want to put people off learning about the industry and it's heritage.
I'm therefore reluctant for it to get too 'techy', a mine might well of extracted various ores or a metal with various chemical names, but if it was commonly known as 'lead' (for example) I think we should stick to classifying it as a lead mine.
Taking LeeW's example there, IF a mine was worked as Ganister in it's own right then I guess it's correct to classify it as Ganister and not coal. Especially as if that's the case and somebody is looking for that mine they are going to have a fairly good level of knowledge to be searching for it, and should therefore find it under the correct classification. If Ganister was a secondary product to coal then it is/was a coal mine.
Ulitimately however the decision is with the person who adds the mine to the database. This could lead to a mine being classified as Coal or Ganister. However with the multiple methods of sarching mines (region, area, landranger, show all, search and name search) I'm sure people will find the mines they are looking for.
Where a product had a regional or by-product name, such as Ashford Black Marble then we'll stick to classifying it as a Limestone quarry.
For metal mines, as JohnnyM says, stick to the common name of the ore they were refining.
Don't forget the Description field can be used to explain more about a mine / quarry. For example if the quarried limestone was polished and sold as Ashford Black Marble, or if small quantities of silver were produced alongside lead.
So I think the list is:
- Bitumen (or should this be bituminous coal)
- Cobalt
- Umber (I don't know enough to know if this is materially different to Ochre which is already in the database)
- Ganister
- Calcite
- Marble (i.e. marble proper)
Hope I've not confused the issue even more!
my orders are to sit here and watch the world go by
