# Description & Notes:
#	Stable isotope data (13C and 18O) of two stalagmites from
#	Spring Valley Caverns Minnesota (SVC-IV - North Crawl)
#	Stalagmites dated by U-Th Series, and isotope data 
#	collected on a Finnigan MAT 252 using a Kiel II device.

#	! Analyses of Cold Water Cave stalagmite 1S are tabuluated in Dorale et al. (1992). 
#	* The total length of SV-1 = 635 mm; SV-2 = 560 mm; MC-28 = 317 mm; CC-A = 311 mm. 
#	§d234Umeasured = [(234U/238U)measured/(234U/238U)eq –1] × 103, where (234U/238U)eq is 
#	the secular equilibrium atomic ratio: lamda238/lamda234 = 5.472 × 10- 5. Values in 
#	parentheses are 2sigma uncertainties. 
#
#	† Ages are relative to the time of measurement, 1994–1996. Ages are calculated using a 
#	modification of the standard age equations (Broecker and Thurber,1965) 
#	modified to correct for initial 230Th assuming an initial 230Th/232Th ratio of 
#	4.4 × 10- 6(± 2.2 × 10- 6). Half lives are those used in Edwards et al. 
#	(1987). Although analytically precise, uncertainty associated with drilling large 
#	(~1 g) samples increases the effective error of these dates.
