What grade is Armenia's Hoktemberyan Tuff? Ask Other Questions
I do not have access to live geologic data. However, based on geological records, the Hoktemberyan Tuff is categorized as an Upper Cretaceous rock formation, which means it is dated to have formed during the Late Cretaceous period, approximately 70-75 million years ago. So, it does not have a specific grade like information about a student.
