The carbonate particles (Figure 20(c)) and pyrite (Figure 20(d)) sometimes show
idiomorphic crystals, which indicates that they were originated from primary sedimentation.
Weakly serpentinized olivine ([Fa.sub.35-44]) is more
idiomorphic in gabbros than in anorthosites.
General appearance: Scattered clusters of
idiomorphic prismatic crystals up to 1 mm long.
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.
Euphoria hit me in the nearby mineralogy collection, chunk by
idiomorphic chunk.
The continuous normal zoning displayed by plagioclase in the two analysed samples for the present study, characterised by Ab-rich contents towards the rim of
idiomorphic prisms (Fig.
The Suursaari quartz porphyry is a good example of a volcanic rapakivi rock, containing
idiomorphic quartz phenocrysts.
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.
Secondary electron and TEM images show that the green material constituting the needle-like coating of the filaments actually consists of
idiomorphic lath-like crystals < 10.5 [micro]m long and < 0.8 [micro]m wide (Fig.
