Lower Palaeozoic metamorphism in the Moine-Dalradian belt of the British Isles

Geological Society London Special Publications (1988)

B. Harte

Summary Greenschist- to amphibolite-facies mineral assemblages occur which are of Proterozoic as well as lower Palaeozoic age in the Moine rocks but are only Lower Palaeozoic in the Dalradian rocks. The widespread age of high-grade metamorphism in the Dalradian is 520–490 Ma (Grampian), whilst in the Moines N of the Great Glen high-grade Lower Palaeozoic metamorphism is dated at 460–440 Ma. In Moine rocks, Grampian deformation and metamorphism may be absent N of the Great Glen but present S of the Great Glen, and this may indicate substantial movement on the Great Glen Fault between about 500 and 450 Ma. In addition to Moine metamorphism and deformation, the 460–440 Ma period appears to encompass diverse and extensive tectonic activity near the southern margin of the belt: thrusting in Connemara, Highland Border Downbend formation in Scotland and ophiolite emplacement in the Shetland Isles. A set of probably basement-controlled tectono-metamorphic domains in the Scottish Dalradian is suggested.

Diffusion in diamond. I. Carbon isotope mapping of natural diamond

Mineralogical Magazine (2009)

John Craven B. Harte David Fisher D. J. Schulze

Abstract Recent advances in ion microprobe instrumentation and techniques have enabled the mapping of C isotope ratios across the whole of a polished plate of a natural diamond from Guaniamo, Venezuela. The resultant map of C isotope variation closely matches the cathodoluminescence image of the growth structure of the diamond and, therefore, indicates an extremely limited scale of diffusion of C atoms sincethetimeof diamond formation. This result is compatible with thelimite d mobility of N atoms shown by theIaAB aggregation stateof thediamond. Inclusions in thediamond aree clogitic, in common with many Guaniamo diamonds with temperatures of formation of around 1200ºC. At such temperature the IaAB aggregation state indicates a mantle residence time on the order of 1 Ga. Such temperatures of formation and mantle residence times are common to many natural diamonds; thus the extremely limited diffusion of C isotopes shown by the mapping indicates that many diamonds will retain the C isotope compositions of their initial formation.

the Cr-poor discrete nodules.However, a straight¬ forward transformation of coarse -* deformed Fe-Ti enriched deformed Iherzolites is not probable because some of the deformed Iherzolites are more magnesian than some of the coarse ones.Hence the relationship of coarse and deformed Iherzolites and Cr-poor dis¬ crete nodules is still uncertain.
