I have a new meteorite (found in Morocco 2019) probably H-type IMB. This impact melt breccia is being classified at the moment, and I see some structures that could look like shatter cones – with reference to the MPOD of Jan. 1st. 2020. See the green lines in photo 2.

I am also interested in a discussion about the possibility of scatter cones in meteorites. This one for sure had a severe collision out there.

Interesting patina and general surface morphology no matter what. Thanks for sharing Jesper!

I believe the specimen of Tatahouine from MPOD 11/06/2012 is a specimen with a shatter cone like-looking feature. I believe Anne mentioned Tatahouine the other day as an example.

I agree, I do not see any shattercones here, just slickensides and if you go look at the pictures of Zag published on MPOD on 9/21/15 you will see good examples of slickensides.

The lineations are *slickenlines* or *slickensides.* I cant post a link here, but there are plenty of explanations on google. In this case, they are shear planes most likely caused by an impact / shock.
