Origins of Bennu

The material looks to be very coarse and rather angular in shape.

Not much evidence of fine dust.

My take on this, David, is that the assemblage formed by gravitational attraction from debris whilst at relatively high, refractory temperatures - quite unlike a comet precursor. I wonder how rich it is in carbon and is any of it in nearly pure elemental form?
