San Andreas Lake (from which the fault takes its name) is a ``sag pond'' that naturally formed in the valley of the San Andreas fault. Strike slip faults are good places for lakes; the fault both creates a low spot to collect the water, and grinds up the rock underneath making an impermeable layer to hold the water in.
In addition to providing us with shape and support for our skeleton, minerals are the âspark of life.â Minerals are essential in the diet and each plays unique and often multi-factorial roles as they act at all levels of the body â cells, tissues, organs, and the whole organism.
Magnesium is a macro-mineral, which, unlike trace minerals, is needed by the body in large amounts. Calcium, sodium, and potassium are also macro-minerals. The average human body contains about 25 grams of magnesium, one of the six essential minerals that must be supplied in the diet.n its ionic form, magnesium has a positive charge, commonly noted as Mg 2+ . Magnesium cations function as a part of the structure of the body through their presence in bone. But arguably more important is their function as cell regulators in hundreds of chemical reactions throughout the body.
