HIGH-PRESSURE MINERALOGY OF SHOCK VEINS IN METEORITES DOES CONSTRAIN THE EQUILIBRIUM SHOCK PRESSURE AND ITS DURATION. P. S. De Carli 1 ,

2009 
A recent paper on helium loss from Martian meteorites states that the high-pressure mineralogy of veins is not a good equilibrium pressure barometer.[1] We respectfully dis-agree. However we do agree with the authors that it is likely that helium loss from Martian meteorites is largely due to shock metamorphism. It is not certain that the shock metamorphism was coincident with the ejection event in every case.
