abstract |
Seven localities distributed along a 180-km-long outcrop within the UK sector of the
Laurentian margin were sampled, and all showed two phases of authigenic K-feldspar.
The first phase was precipitated from a cool fluid of moderate salinity, and the second
phase was precipitated from a hotter, more saline fluid. Ar-Ar ages for the two episodes
of authigenesis are ca. 470 Ma and ca. 432 Ma. The data can be interpreted to represent
two phases of regional-scale fluid migration related to Ordovician arc accretion and
Silurian continent-continent convergence, corresponding to the Grampian and Scandian
episodes of the Caledonian orogeny, respectively. |
