This is likely a question which is to be regarded idiotic by Metallurgists and Geologists alike, but I think such Characterization have never been tried.

Si, Al, Fe, Ca, Na, K, Mg, Ti

There are binary/ternary alloys regarding these elements with extremely diverse range of application (Structural, Aeronautical, Chemical, Biomedical, Electronic), but not in that particular ratio.

The metal can be approx. 52.5% Si, 15.5% Al, 9.5% Fe,8% Ca, 4.75% of Na and Ca each, 4% K and 1%Ti , all weight %

There are several theoretical interest related to this question.

  • "standard " rock composition for various rocks (especially igneous) have been well documented in several textbooks, and "standard" composition of idealized-composition minerals is also possible to be determined. Direct Electrolytic/ Carbothermic reduction of rock samples may not be possible, but what if metals of experimentally calculated composition are mixed with each other in a liquid/powder state and heated, possibly held by the very rock materials whose metallic composition is matched with metal?
  • Would that be a high-entropy alloy/medium entropy alloy with phase separation?
  • If the bulk metal is let to "weather" like rocks, what kind of materials would form in its surface? Would they have any physical correlation with original rock after which the metal is modelled?
  • I can rarely find data with Si-Al-Fe alloys (they are technologically harmful) let alone this alloy mixture. Can CALPHAD approach predict possible phase diagram?(the one available for free)
  • would there be any practical application of such alloy?
