Jiesen Posted June 20 Share Posted June 20 What are these five rocks, please? (Let's number them 1 - 5, from left to right.) They're from a geoscience professor's collection, and were given to me without ANY other information, so I can't provide any geographic or stratigraphic information whatsoever. Number 1 = basalt? Number 2 = agate? jadeite? something else? Number 3 = ? Number 4 is very smooth and milky-like. Mudstone of some sort? Number 5 = calcite? Thank you for any help!
