ROCKS???

[Frodo]

Does any one here know anything about rocks?

This is my little rock garden, Does anyone know what the rock is that has the arrow pointed at it?
The other image is a closer shot, As you can see i have 4 or 5 of these interesting rocks but do not know the name of them

I asked Hubby who knows a lot more about rocks than I do. He's trying to remember the word. Said it's a sedimentary rock but can't remember what kind. (I thought it looked like petrified tree)

I took an earth science class in college and one of the things we had to do was to look at rocks and identify them. I can tell you that that is not easy and since that was many years ago, getting harder. It is a little easier to tell if it is sedimentary, metamorphic or igneous.

I think it is a sedimentary rock as well, but it could be metamorphic because of the resemblance to a tree. It is hard to tell from photos. It may be sandstone, or not. And it could be a petrified tree, as Lady Locust said.

Daughter and I collect heart shaped rocks. I have them in a bed around a tree. When the dams were being built in South Dakota in the 1950-1960's, there were many fossils that were dug up. My dad would bring home petrified fish and other fossils.

not a petrified tree. it reminds me of sand stone but is not soft like sand stone

Do you remember where you got it?

Sometimes water flows form things like that, when we spent time out on the desert of northern Nevada we ran across mud pumps, kind of salad bowl shaped sand, gravel materials made from up flow of water that carries lots of minerals which are highly alkaline, basically concrete, often called caliche, often small gold nuggets get covered with caliche, we'd drop them in CLR and the mild acid clears the caliche off. Also lava flows make things like that, but more often they are six sided columns. The stone with the RR spike on it looks like Rhyolite, garnet crystals often form in pockets like that stone has, mom and step dad took me out rock hounding near Baily, Colorado and a mound on the south side was all Rhyolite and almost every pocket had garnet crystals in them about the size of a pea and looked like they were hand faceted.

Sand stone, we find it here in the sandy hill side, when roads are cut.

We have a lot of sandstone here as well. When the subdivision was being built I had a neighbor who was a landscaper. He helped me quite a bit, and we had almost unlimited access to rocks from the other houses that were being built and the foundations being dug. We ended up with a really nice fossil . Looks to me like it was a fish, but it is quite visible on the face of the stone.
