Mineral Evolution Database

Created and maintained by the Mineral Evolution Project in partnership with RRUFF and mindat.

Mineral locality data provided by mindat.org

The Mineral Evolution database is currently under development.

The goal of this page is to present localities at which the mineral is found, and estimates of the oldest possible geologic age of the minerals at these localities.

(1985)	10.1144/gsjgs.142.6.1159	JGSL142_1159	Statistically acceptable whole rock and/or mineral isochrons were obtained for each of the granites studies and a preliminary inspection of the tata may suggst several episodes of of Hercynian magmatism in SW England. The first, c.. 290 generated the Carnmenellis, Bodmin and St Austell granites and was succeeded some 10 Ma by the Dartmoor grantie, and finally the intrusion of the Land's End granite at 270 Ma. The emplacement of the porphyry dyke and the main phase of mineralization, would then be closely associated with the second and third magmatic episodes. However more detailed examintation of the data and comparison with other work reveals certain major discrepencies in the hypothesis.
