“…As they are ‘pretectonic or early syntectonic’ with respect to cleavage (Seccombe & Hicks 1989 p. 261; Windh 1995 figure 6D), they must pre‐date the regional metamorphism, which should post‐date (Packham 1999) or perhaps syn‐date the main deformation. Thus we find no basis for assigning the early 420°C event to metamorphism. (2) Peak pressure The 2.9 kb pressure estimate (290 MPa or ∼11 km burial: Packham 1999) that Seccombe and Hicks (1989) and Lu and Seccombe (1993) linked to the 420°C temperature was based on ‘metamorphic white mica’ from the host rocks (Lu & Seccombe 1993 p. 311) rather than on muscovite from the veins. It therefore relates to the metamorphism.…”
