I am continually drawn to find agates whenever I walk at Damon Point. Why, and what are they exactly?
"Most agates occur as nodules in former cavities produced by "Volatiles" in the original molten mass, which were then filled, wholly or partially, by siliceous matter deposited in regular layers upon the walls. Agate has also been known to fill veins or cracks in volcanic or altered rock underlain by granitic intrusive masses." ~ Wiki
So, they're made from molten, gelatinous mineral that filled in empty spaces in volcanic rock. The predominant mineral in them is chalcedony, a microcrystalline type of quartz. Wiki goe on to say that agates are often pitted on the outside due to the original outer layer being removed. For the full article, read HERE.
One source spoke specifically about the AGATES common to the Damon Point area, here on the Washington coast.
Apparently agates have more properties than I realized... maybe those that I've collected are what caused the imminent 'storm of the century' to pass by us last month! Haha!
