Only rocks with very distinctive cleavage can be identified from it, like slate.

Even then, it's best to have a second way to identify them.

The image doesn't show for me either but you can always quote the post to obtain the image URL and then copy/paste it into another tab to view it.

EDIT: Well I can see the image now...

Also, how are you ID'ing the rocks and minerals? Do you take pics off the internet and study them or do you have a collection of R/M that you use?

We haven't officially started yet, but I would think that actual samples would be better, because you get to feel the specimen, the weight, and all those details.

Books, Googling, and the Wiki page should all help - pictures should be especially useful if you can't get ahold of a sample.

Request a bunch of field guides from the public library...I have an entire stack of fields guides for rocks and minerals at home...
Also, if you print out high-quality pictures and put them on index cards, you can test yourself...it worked really well for fossils...

just wondering...as i noticed in the question marathon...how does one determine the cleavage of a rock only visually and use that to ID the specimen? Also i dont really understand the different directions of cleavage that a rock is said to have?

Does anyone know what Limsetone [Crystalline] is in comparison to the other types...I couldn't find it online or any picture that distinguished between the others
