Thanks, MagBem. Roger that on your magnetism comment and of possibility for other ferrous oxides. It will be interesting to see what I can learn beyond a list of elements from xrf. So far: I'd like to CT scan the head on the concretion to see if it reveals any clues, then (as EdStainless and...
Thank you MFAMET. You are right. The XRF method is capable to detect and quantify the element contents only. Not oxides. The reports were provided in oxides after recalculation. Geological reports are commonly reported in major oxides. I did not know to stipulate otherwise.
Thank you...
Attached photo is of sample 2. It does appear to have solid metal on the inside. It broke open and in pieces when I accidentally dropped it. I sent off half of the tip end for xrf testing. The other half is available for microstructure evaluation. Who can do this? I'm a novice and what I've...
Hi. I'm a retired helicopter engineer that's taken on a project to analyze concretions found in the bay. I can tell they contain iron because they attract to a magnet. One looks like it might be a ship spike, the other was on a small plank (either side of nail hole). I imagine that they might be...
