Wad: Mineral information, data and localiti

Wad, wadd, and/or wadt were used as early miner's terms and used for various black mineral substanc The redundant name "black wad" has been frequently attributed to Richard Kirwan in his Elements of Mineralogy (1784) but Kirwan mentioned, but did not cite, neither Josiah Wedgwood's (1783) analysis of "black wadd" nor contemporary experiments with wad by Joseph Banks, nor any earlier.

Archaean greenstone belts and associated granitic rocks

1/12/2014· Archaean granite-greenstone terranes, particularly those of Western Australia and Zimbabwe have a distinctive geotectonic style that led Macgregor (1951) to introduce the idea of “gregarious batholiths” to explain the structure of the Zimbabwe Craton Later Anhaeusser et al (1969) noted that this pattern of Archaean granite-greenstone development was prevalent on most cratons where.
