 3.0 DATA SUMMARY
Rock mass, rock volume and soil coarse fraction (% v/v) for the 0-30 and 30-60 cm portions of the soil profile across the TDE site.

 4.0 PROCEDURES
Cores of soil from 0-30 or from 30-60 cm deep were obtained in ~10 cm diameter cylindrical cores with a total volume of  2430.96 cm3.  To convert rock mass to rock volume all rock (i.e., chert) was assumed to have a mean density of 2.3 g cm-3.   This density was based on laboratory observations for chert take from the TDE samples.

 5.0 OBSERVATION NOTES
None
