conchoidal/subconchoidal : LUSENET : Introductory Geology, Oswego State : One Thread

In answers people write the difference between conchoidal and sub-conchoidal is that conchoidal has a faint, concentric striation. What is a faint, concentric striation or what does it look like?

Concentric striations are like the ridges that you see on a seashell, so faint concenteic striations are light cruved lines on the fracture.
