@PrittBalagopal, here's what I think this guy did: He submitted a question, which I answered. My answer didn't quite hit what he was looking for, so rather than asking for clarification via comment, he created a new account and asked almost the same question. If you have not flagged it yet, I will.
@PrittBalagopal , I just saw the second question in the review cue as a duplicate of his first question (looks like Mithoron marked it as dup). I'll leave him/her a note in the comments regarding how to ask for clarification on a question (i.e. don't just create a new user and ask a new question!)
What do Greek letters in front of the formulas for minerals/inorganic compounds mean, such as $\gamma\textit{-}\ce{Al2O3}$ or $\alpha\textit{-}\ce{Fe2O3}$?
