Abstract
It is widely accepted in the literature that polycrystalline minerals, ceramics, and rocks containing subcontinuous intergranular films of solvent or melt can deform by diffusive mass transfer through the grain-boundary liquid phase (Durney 1972, Robin 1978, Raj 1982, Rutter 1983, Cooper & Kohlstedt 1984). This type of mechanism is generally referred to as fluid-phase diffusional creep (Stocker & Ashby 1973), solution-precipitation creep (Raj 1982), or pressure solution (e.g. Rutter 1983), and is of well known interest both in materials science (see Lange et al. 1980, Raj & Chyung 1981, Raj 1982) and in the Earth sciences (see Robin 1978, Rutter & Mainprice 1978, Rutter 1983, Green 1984, Urai et al. 1986). In the present chapter we shall use the term ‘fluid-phase diffusional creep’ (FPDC) for the process. For mechanisms involving coupled solid-state flow plus dissolution at grain-contact margins (Pharr & Ashby 1983, Green 1984) we shall use the term ‘dissolution-coupled creep’.
