kerryrocksnla Posted September 2, 2014 Share Posted September 2, 2014 Unsure of what kind... Central Louisiana Rock/Fossil Hunter! Link to comment Share on other sites More sharing options...
tmaier Posted September 2, 2014 Share Posted September 2, 2014 The one on the far right is iron concretion. They grow from high iron salts in the water to take on weird bulbous shapes. http://www.google.com/images?q=iron+conceretion&hl=en&gbv=1&sa=X&oi=image_result_group&ei=fjkGVIn2CM-7ggSGqoCoAQ&ved=0CB8QsAQ Is that second one an agate? http://www.google.com/images?q=agate&btnG=Search&hl=en&gbv=1 Link to comment Share on other sites More sharing options...
Herb Posted September 2, 2014 Share Posted September 2, 2014 interesting, but I don't think there are any fossils.

howard_l Posted September 2, 2014 Share Posted September 2, 2014 I don't see any fossil preservation in these. Just odd shaped rocks. To identify what kind we would need to know the hardness, grain size, if vinegar makes it fizz and if you have a old bathroom tile, check the streak color by rubbing the rock on the back of it. A broken edge to see a fresh surface would help. Howard_L http://triloman.wix.com/kentucky-fossils Link to comment Share on other sites More sharing options...
tmaier Posted September 2, 2014 Share Posted September 2, 2014 OK, I'll take a shot at this... 1.) Rose quartz? If it scratches galss, then that is probably right. 2.) I'm still going with agate on this. 3.) Upper left, sandstone upper right, white quartz lower left, limestone with some type of inclusion in it (which just means it has a dark thing that I don't know what it is ) lower right, sedimentary stone showing layers of deposit 4.) iron concretion, I real sure about that one.

kerryrocksnla Posted September 3, 2014 Author Share Posted September 3, 2014 Thanks for the input. Ive never seen an agate rock in whole. Ive only seen smaller types which show the bands in them. But now im interested in cutting it open.. " if only I knew how". I will be going to my first rock & mineral society meeting, & I will bring it for show & tell. ... Ty.
