88

 

Sleaford Bay diopsidite (SBD) starting material.

89

 

SBD shortened 52% at 1100°C, 10-5/sec and 1200 MPa; regime 2 dislocation creep.

90

 

SBD shortened 32% at 1200°C, 10-6/sec and 1200 MPa; regime 3 dislocation creep.

 

 

 

 

91

 

Maryland diabase (MD) starting material; ~35% plagioclase, ~60% clinopyroxene, ~5% opaques and chlorite.

92

 

MD shortened 50% at 1000°C, 10-4/sec and 1200 MPa; pyroxene is stronger and forms augen.
