In all entities from this site (JX-6 (entity_id = 286), JX-2 (entity_id = 287), JX-10 (entity_id = 288) and JX-7 (entity_id = 289)): Average crustal value for initial 230Th/232Th atomic ratio = 4.4 +- 2.2 ppm (assuming bulk earth 232Th/238U value of 3.8). Decay constants are 9.1577E-06 year-1 for 230Th, 2.8263E-06 year-1 for 234U and 1.55125E-10 year-1 for 238U.// JX-6 (entity_id = 286) was corrected for aragonite in the 2013 paper. Original values (0.38 permil lower) are reported here.
