Abstract
Mobilities of elements in magmas have an important bearing on quantitative understanding of geochemical processes. Mixing of magmas, assimilation of xenoliths, contamination of magmas, and interaction between magma and wallrocks are all related to diffusive transport of elements in magmas. Diffusion also plays an important role in processes of crystal growth from magma. Thus, the determination of element mobilities in magmas has an immediate geologic interest and its significance is to constrain time and/or spatial scale lengths of these processes.
