The Complex Geology is Complex!
It is starting to feel like there will be many many deposits to be uncovered and each will be somewhat unique in its composition and structure.
This nothing at all like Exploring Sedimentary Rock formations. It will more likely be analogous to discovering the Green Beans under the surface of a big pot of stew. Then, with in each Green Bean there will be several different types of Spice and Seasonong consentrated. In other places they will find Waxed Beans instead and inside them there will be many of the same Spices and Reasonings in concentration. To find the Beans, be they Green or Yellow, they have to push thin straws into the stew in places where they detect these vegetables by the bumps they create in the smooth textured gravey. All the other Vegetables produce similar types of bumps. All the different bumps are distinguishable only by use of very fancy tools in the hands of only the best of chefs.
For all of us who do love this kind of food, we need to sit back and await their searching and reporting to us. When we get sufficient searching and reporting in our bowls we can expect the big buys to start offering to take possession of the Pot we are all feeding from.
