Dear Santa, I believe you should wear your specs a little more often, this may perhaps allow you to see a little farther and perspect a much broader range of vision.

If you examine the recorded geology on all of the SLI properties, you will see quite often, the unique factor of having so many different types of deposition vehicles. Volcanics/ hydrothermal ejections play an important part in mineral deposition, and are responsible for mineral deposition, even your host rocks were formed this way.

I believe you should also take into account, the important subduction zone that transends the Andes, and is part of what is know as the volcanic "Ring of Fire". You should also appreciate that there are sea shells and what resemble "old sea ports", 2 miles above sea level in the Andes. There is more to tell you, but perhaps you would have difficulty seeing it, if you don,t put your glasses on. Clairity sometimes comes easier, with the help of visional aids.

Here is a little info to read over the winter, while you are resting.
