Rock Classification
Posted: 26 Aug 2008, 13:30
Hi everyone,
Does anyone have a list of the old numerical classification of rocks? Ours have two different systems - one's a number, and the other's a letter and number
I am back onto rocks again - trying to classifiy and organise the many, many rocks that are living in drawers in most of the Labs here. I'm sure they're multiplying! We're having a huge clean-out of the Faculty, and have far more of these beautiful specimens than are needed. Most of them are too big to use for class sets - what I plan to do is to break up enough for maybe 5 class sets of each, then the rest will go.
Since I've been here, I've reorganised the 40 or 50 drawers of rocks that were in my Prep Room - few years back we had a day where all the local labbies came to listen to a geology trained teacher, and we had some fun learning to identify & classify what was in all those drawers! That was a great start, and from there I was able to make up class sets of most things, that we've been using since.
However, a list of the numbers would be a great help with this much bigger job. There are old collections from staff long gone, plus boxes collected on field trips last century!
Here's a few examples of what I'm referring to:
Serpentine 41 M6
Granite 31 I4
Coal S6
Schist 73
Conglomerate 54
I'm presuming the M,I and S stand for Metamorphic, Igneous and Sedimentary?
I've done a search on the previous posts on here - Rhonda from Hornsby Girls High was sorting hers at one stage - would you be able to fax me your list please?
I also saw the post where Lorrae suggested Geological Specimen Supplies, so I'll give them a ring too.
It's worth asking again though, in case someone else recognises the system we've got here.
I promise to let you all know what's left over too - maybe someone wants some! But not an overnight job, this one......... (then there's all the fossils, too....)
Many thanks,
