Dear list,
I am involved with a project relating to the archaeology (in England) of substances which are or have been gangue and would welcome comments on and assistance with the following.
1) Various definitions of gangue have been published and seem to come down to 'unwanted materials which have to be raised with an ore being sought', would anyone add to or subtract from that definition?
2) I cannot find anything approaching a comprehensive list of gangue substances which were ultimately found to be useful or which could have left potential archaeological traces. What should I add or subtract from this list?
aragonite,
arsenopyrite,
barite,
calcite,
dolomite
fluorite,
fluorspar,
haematite,
manganese ores,
ochre,
pyrite,
quartz,
strontite,
tourmaline,
witherite,
zinc ores,
3) I would be interested to hear from anyone with an interest in such materials or with information on site surveys or archaeological investigations of appropriate sites.
