| Lucy_040b | 280 | 280 | 280 | Rb-Sr | Preliminary examindation yields age of Dartmoor as the second episode of Hercynian Magmatism. | Yes | 1620 | Devon, England, UK | Dartmoor Granite | Darbyshire et al. (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. | ||||||||
