Entity_Type:

Entity_Type_Label: Appendix_4.csv
Entity_Type_Definition:

Analyses of carbon, oxygen, and sulfur isotopes, weight percent total carbon, and inorganic geochemical analyses for samples from the Cox Ranch (HP8) drill core and other drill cores. Major and trace elements determined by a) X-ray fluorescence and ICP-AES-MS after sodium peroxide fusion; b) automated LECO analyzer (total S); and c) carbonate carbon (coulometric titration) subtracted from total carbon (analyzed by combustion/infrared detection) to obtain TOC (expressed in wt%). Standards (Ohio Shale SDO-1) were run to monitor accuracy. Appendix_4.xlsx presents the Cox Ranch data and the other drill hole data on separate worksheets. Appendix_4.csv presents data from both worksheets in a single csv file.
