I am intetested in the chemistry of caliche....major elements and specially the trace element composition
There are a range of answers to that.I have been working on the chemistry of nitrogen-bearing caliche, especially where it overlies copper deposits. Caliche can be a sponge for many elements, and provide a detailed record of different sources over time. Hope this helps for starters, and good luck!
I also suggest reading the following:

Thank you Erik
If possible, can you share with me the PDFs of the two first papers, unfortunately I do not have access to those journals.
Thanks
