Figure 1 CENTRAL) Field sketch of sheared diatexite in Six Mile Lagoon. a) Dextral shearing on N60-70E of schollen preserved in magma-rich diatexite, b)Funnel-shaped N-directed channels draining magmas from same diatexite a few meters to the right (East) of (a). This outcrop has therefore two parallel processes occurring simultaneously during anatexis: dextral shearing on N70E and melt extraction through channels trending N-S. Boxes mark details shown on photographs. |
