They sure are giving this abrasion a very thorough look. What are they seeing in it? IANAGOAA (I am neither a geologist or an astrobiologist)
There have been no updates from JPL at this time, it's usually quite a while (many months) before they share any advance info on the chemistry of an abrasion or after a core, if I see anything, I'll be sure to share it here
Update - There is a possible explanation in the latest Mars Guy video https://youtu.be/UJRJzTa1atg
