chainsaw Posted April 24, 2009 Share Posted April 24, 2009 I was at work today and found this in some gravel hauled in along side a bulding, it looks like sand stone? I am not sure if it is anything at all thanks for any input. Link to comment Share on other sites More sharing options...

tracer Posted April 24, 2009 Share Posted April 24, 2009 kind of hard to tell. it looks more like limestone than sandstone to be, but not sure from the pics. the top pictures of the rock almost have a "dragged" look like sedimentary rock where a fault cause slippage against other rock and shaped it. the "peanut" nodule-looking pictures look like, well, kinda nodular. I don't really feel like the shapes are of macro fossils, but if it's limestone, it's probably made of microfossils... sorry not to be more help but don't know. thanks for posting the pics, though. it's fun trying to ID stuff.

Shamalama Posted April 24, 2009 Share Posted April 24, 2009 Looks like some kind of rock that has experienced selective dissolution. Some of the weaker parts were dissolved or worn away before the harder parts. -Dave __________________________________________________ Geologists on the whole are inconsistent drivers.

(i dint know where to put the possessive). Link to comment Share on other sites More sharing options...

geodan03 Posted April 28, 2009 Share Posted April 28, 2009 Looks similar to some limestone i had identified on this forum a few months ago. It is called slickensides. Similar, but not exactly like mine. Due to calcite crystal growth. Maybe. Link to comment Share on other sites More sharing options...
