Ground Mineralization Question

I've heard and read that ground mineralization varies a lot from place to place. Ever since I got my detector, I've wondered just how mineralized the soil is here in Hawaii, and thus if I'm losing significant depth due to ground mineralization. Then I remembered that the ground here isn't very old as compared to other parts of the U.S., as the islands here were created by still-active volcanoes. As a result, the only rocks and soil we have here naturally are igneous and have come directly from the volcano (not acted upon by the elements, like soil in mineralized areas). Does this mean that soil here should contain little or no mineralization? I'm just curious and looking for some feedback on this theory.
 
Hmm, carbon is conductive. Magma might be presumed to have at least some natural iron in it, being our planet's core is iron 'n' all.

But, ya know, in all my years of reading detector forums, I've never read a post about how bad detecting is in Hawaii due to all the lava. I've read more about good finds on the beaches there.

I say go for it and try some all-metal readings in any lava deposits nearby to see if you notice higher readings. If your detector has an ID feature, try a coin in your hand well above the soil and again, with the coin placed on top of the soil. If the coin's ID changes, it's sure to be a result of soil mineralization.
