SpaceRockNoob 1 Posted January 30, 2019 Share Posted January 30, 2019 I found this rock in a sedimentary environment, half-embedded in an eroded plain. it is very heavy at 600 grams. I am wondering if it is: 1) a volcanic rock of sorts, as there was a lot of fully exposed basalt lying around. 2) a Native American hand tool, given the perfection with which it fits in my palm and the smooth surface where a striking area might be. Any help with its diagnosis would be greatly appreciated. MB . Quote Link to post Share on other sites
Edge 524 Posted February 4, 2019 Share Posted February 4, 2019 I'd rule out a stone tool, has zero appearance of being tooled. 1 Quote Link to post Share on other sites
d_day 310 Posted February 5, 2019 Share Posted February 5, 2019 Just looks like a hunk of basalt to me. Quote Link to post Share on other sites
4meter 186 Posted February 5, 2019 Share Posted February 5, 2019 My best guess is that the rock is a "sandy conglomerate". The supporting matrix of the rock is composed of "sand" sized particles and these support the well rounded larger pebbles; all of the material is well cemented together probably by quart. Most likely a stream deposit that was later covered by basalt flows. It is very common to see these type of rock layers here in the southwestern USA. Quote Link to post Share on other sites
