Comment:
The average size is for all shocked quartz in the sample, except for North American sites for which the average is based upon 100 measured grains. Similarly, the number of PDF in each quartz grain is for all shocked quartz grains in a sample, except for North American sites for which the values are determined from 100 quartz grains. North America samples fireball layers only
