Detrital Quartz and K-Feldspar in Quartzites as Indicators of Oxygen Isotope Exchange KineticsOxygen isotope fractionation between coexisting minerals may indicate equilibrium or disequilibrium, provided the temperature of formation is known. Depending on the time of blocking of specific .O/.O ratios, the fractionations contain information on:

For those who are unfamiliar with the Scottish Highlands, the purpose of this chapter is to give some background to the nature of the Caledonian orogeny in Scotland, the Dalradian Supergroup and the late Caledonian granitoids.

A section on solidus temperatures and the granite system (Sect. 4.1.4) introduces several condensed paragraphs on mineral chemistry, phase relationships and geothermometry (Sect. 4.2; see Weiss and Troll 1989 for further details). The implications for fluid activity and the o

Two schematic petrogenetic grids are derived: the first is for mineral assemblages below the onset of partial melting, which define the mapped isograds in Maps 1 and 2 and Figure. 8.1; and the second is for high-grade mineral assemblages which occur sporadi

In this chapter we summarize that evidence as seen both in the field and under the optical microscope. We endeavour in our presentation to largely keep description and interpretation in separate sub-sections,
