ResearchTule Tank Crater
Pre-Matuyama (+2.6 Ma)
Matuyama (2.6 Ma – 800 ka)
Brunhes (800 ka - Present)
Conclusions
•Preliminary data show some consistencies with Matuyama age of eruption
•Alteration of samples’ magnetization has likely occurred
•Further analysis is needed before conclusions are interpreted
