Dear Meryem, a geological map would represent the best way to present your samples, because it would provide the necessary context for their interpretation (lithology, alteration, structural framework). Kind regards, Daniel

Dear Mrs. Redouane:

The primary question is what sort of spectrometric data did you capture in the field and what is the scope of your study. Based upon that I can give you some answers because colleagues and I did what is called capturing digital data in the field. The second question is, have you done some supplementary work such as determination of the apparent resistivity or susceptibility of the lithologies in question. Is the spectrometry all done foot-borne or also supported by aero-spectrometry, e.g., K, U and Th?

I took samples of volcanic rocks presented in the field and did the spectrometry analysis on them.. The results were names of alteration minerals.

Dear Mrs. Redoune:

It sounds to me like IR spectroscopy which is the base of PIMA (short wave IR). Does the readout look like that ?

H.G.Dill

Primero que deceas obtener con estos resultados, donde los vas a aplicar , y en función de ello puedes realizar el mapeo que te estan indicando.

Harald G. Dill , sorry for the late reply Mr. Gill, and thank you for asking.

The readout is an excel file with the name of existing minerlas in the sample, I actually don't know much about the method, the thing is that I applied for it to be done so I can have an idea about the alteration minerals I have, and so deduct the T-P parameters.

So I actually have it already, but I wondered what else can be done with it? is there any software that regulate the process of precising those parameters etc.?

It is a mineral association representative of an oxidizing alteration mineralization with prevalently clay minerals indicative of alkaline solutions. Only samples with kaolinite and jarosite point to acidic solutions. This is a quick-look assessment of mine.

I wish you much success

H.G.Dill

many thanks Mr. Dill
