XuM Movie of Glassy Spherule
This glassy spherule contains a myriad of spherical internal pores, the largest of which has a diameter of 63µm. The rotational movie reveals that this pore has not penetrated the surface. If you take a while to look at the dense inclusion, you will see that it is made up of a chain of plates arranged at different angles to each other. These plates are most certainly ilmenite.
