Which properties are most useful to identify a mineral? Explain

Answer 1

Since this is not my area of expertise, I searched Google under the key words "mineral properties" to get these possible sources:

http://www.galleries.com/minerals/physical.htm
http://www.galleries.com/minerals/property/cleavage.htm
http://webmineral.com/determin.shtml
(Broken Link Removed)

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.

I hope this helps. Thanks for asking.
