Given the pervasiveness of Australian tariff policy, the significant welfare implications of changes in that policy and the particular importance of international trade for this country, ensuing from its idiomorphic cultural, resource-endowment, and geographic characteristics, (5) considerable research effort has been invested in the examination of various dimensions of this issue.

From the lowest to the upper, these units are [12, 13] (i) B3 facies (-880 to -750 m), which contains euhedral pink-colored K-feldspars, zinnwaldites, and hosts commonly micaschists enclaves with quartz-ferberite veins; (ii) B2 facies (-750 to -450 m) consisting of a lepidolite-rich granular granite with idiomorphic quartz crystals and small amounts of K-feldspars; (iii) B1 facies (-450 to -100 m) corresponding to an albite-lepidolite-rich granite containing globular quartz crystals with typical "snowball" textures and rare anhedral perthitic K-feldspars.

In the case of albitization (94.7% albite, 3.9% anorthite, 1.4% orthoclase), the original twinning structure is still apparent, except where plagioclase bas altered to illite or carbonates, Idiomorphic olivine is present as microporphyroblasts, nearly always completely altered.
