Hi Martin,

Here is an excerpt from our noble gas abstract for NWA 7034, Cartwright et al.:

"We obtain T3, T21 and T38 ages of 5.1 Ma, 11.4 Ma and 5.4 Ma
respectively. The older T21 age may result from heteorgeniety of
target elements like Ca and Mg within the breccia. T3 has little
dependency on chemical composition (and T38 also less than T21), and
with elevated 4He concenrations, perhaps 3He loss was minimal, and
thus this age real. A CRE age > 5 Ma is older than observed previously
for shergottite CRE ages, though the 11.4Ma age is similar to Nakhlite
/ Chassigny CRE ages."

So it's not carved in stone quite yet...
