For those who are interested, I updated my page on Tamdakht and added a Back Scattered Electrons (BSE) image supplied by Albert Jambon.
- We know that it is an H according to:
1) The magnetic susceptibility (= quantity of metal)
2) the composition of minerals (olivine + pyroxene)
- The metamorphic type 5 (to verify) depends on the degree of equilibration between minerals and (in the second order) of the texture (not only chondrules, but also size of feldspars and metal-sulphide areas).
Here it is certain that it is neither a type 3 nor a type 6.
A preliminary declaration was sent to the MetSoc, result of the French-Moroccan cooperation.
Best wishes,
Philippe
