Fig. 1

The particles in the EHC-93 sample observed by scanning electron microscopy at various magnifications to show the contents in the particulate matter. a is a 100X magnification image of the particles (scale bar is 100 μm). b and c are 500X magnification images of the particles (scale bars are 10 μm) that shows the majority of the particles have the appearance of mineral particles, where the arrow in c points to a spherical ordered particle (biological origin). d is a 1,000X magnification image (scale bar is μm), and it shows a thin rod (arrow) in the middle of the image
