WebFeb 1, 2004 · The harzburgite wall-rock can be subdivided into two zones based upon textural, mineralogical and geochemical data: (1) an inner zone <25 cm from the main pyroxenite dyke and (2) an outer zone >25 cm from the main dyke (Bodinier et al., 1990). This boundary is basically coincident with the most distant lherzite vein from the main dyke.
