Identity HelpBrown mineral from Norway that I cannot identify!
Hi all of you!
I am having a hard time to identify this brown mineral that I found in Austmannalia roadcut, Røldal, Odda, Hordaland, Norway. It has a streak similar to its color, is rather soft (loosens when scratched against the porcelain). My first thoughts goes towards some kind of Fe-hydroxide-oxide mineral, but I am not sure. Would greatly appreciate some input on what I have found.

Can we please see a photo from the other side too? Looks indeed like a limonite pseudomorph after ... hmm ... marcasite? , siderite?
Will a crumble attracted by a magnet after you made it glowing with a gas torch? This is the other side, mostly quartz and some moss.
Great suggestion with limonite. I did some research and found that hematite indeed hydrate into limonite and found the first picture that shows hematite and limonite (from google). I actually have an other specimen from this location that I also found during my time there (second picture) and it looks almost the same. So you are probably right, it is hametite that has hydrated into limotite. Something that I found interesting is the structure of the limonite, something that i cannot explain.
