Description
This upload contains the 40Ar/39Ar geochronology age determination of sample D9-24 (KH-17-J01-D9-24) from Ontong Java Plateau in Pacific Ocean (Ontong Java Plateau) and was calculated using the ArArCALC freeware. No meaningful age was determined with this experiment. The age determination was carried out on a sample of basalt (plagioclase) in an incremental heating experiment and using the bulk laser heating extraction method. The analyses were run on a ARGUS-VI mass spectrometer and the ages were calculated relative to flux monitor FCT-NM (1E13-21) (sanidine) with an age of 28.201 ± 0.082 Ma. This sample was collected by Takashi Sano (sano@kahaku.go.jp). Sample Description: Standard full leach + 5 min 5% HF. |

Instructions
This ERDA upload contains four separate 40Ar/39Ar age calculation files generated with ArArCALC. Both the XLS and PDF files are for easy viewing in Microsoft Excel or Adobe Acrobat Reader, whereas the AGE file is readable by the ArArCALC software only and the XML file is generated for the GEOCHRON online database project. For full age calculation functionality it is recommended that you open the AGE file in the ArArCALC software that is available as freeware online at http://earthref.org/ArArCALC ... |
