Carboniferous granite intrusions are a relatively uncontroversial element in the geological history of the Sudetes in SW Poland. The Sr-isotope systems in these granites show geological scatter indicative of contamination by crustal rock, failure to homogenise during intrusion/crystallisation and inheritance from source. Rb-Sr ages are thus somewhat compromised and imprecise. The granites originated from a relatively primitive source that underlay much of the region in Carboniferous times.
