Short travelled or long travelled sediment.

Reply Thu 23 Feb, 2017 04:24 am
I have quite a strange situation in one of my thin sections, I am looking at fluvial sediments and in one of my thin sections there is not a single feldspar which is usually a sign of a long travelled sediment but the quartz grains are really angular which usually implies the opposite. There are not any feldspar poor rock in the potential sources of the sediment.

Any Idea ?
