[QUOTE="user 4386, post: 434580, member: 4386"] Too much searching - i.e. relating rocks to assays, need totals from analyses (since Si not determined - it will be most of the balance I would think). High Ti is in the eye of the beholder a bit (even black slate can exceed 1% Ti) - one needs to look at it in conjunction with Ni, Cr etc. (the low The high iron sample is fairly obvious. Sorry, too time consuming - if you show small representative images of the samples with their sample numbers next to them, and tabulate the analyses into a simple table with totals, I will have another look. e.g. 560 ppm = 0.056% etc. I would only include elements equal or greater than 1000 ppm = 0.1% in your table. Your analyses will hold the answer, and I could give you the reasoning. I would not be interested in those Pt and Pd values - they simply mean that they can just be detected, not that they are obvious (refer to detection limits). Even if they were ten times that they would suggest little, in rocks so low in Mg, Ni and Cr. [/QUOTE]
