Hi Thanks for offering this - i have three rocks i am struggling to find what they are the first two are very very light with a little appearance of wood. any ideas? The third one is an interesting stone, is is raw Amber? My daughter is into rocks, minerals and fossils but not so good at keeping records - so not sure where she got it but probably in the UK

First two look like slate (stuff that Trilobites are usually found in), bottom two look like calcite crystals. Not sure about the other two.

#1 Is either slate or basalt.
#2 No idea, a metamorphic thing.
#3 Is either quartz or quartzite, I'd guess.
