“Information will include a summary of the size of the quake, a map of the affected areas, and tips to safely navigate the aftermath. Oftentimes, you really want to know whether you just felt a small earthquake nearby, or a larger earthquake farther away. The map will show areas that shook with various intensities (known as a shakemap), so you’ll be able to quickly assess the reach of the earthquake as well as its epicenter.”
Minerals are combinations of chemical elements arranged into crystalline structures. Earth's rocks are built from different aggregations. Think of feldspar, quartz and mica - these are the ubiquitous species that everyone knows.
But cobaltominite, abelsonite, fingerite, edoylerite - these are examples that will not form unless the "cooking conditions" are absolutely perfect.
The atomic ingredients must sum exactly, the temperature must be precise to the degree, and the pressure will have to be defined in the narrowest of margins.
And then, some will immediately fall apart when they get wet or the sun shines on them.
A negative of having bird feeders = the sprouting of the seeds the birds spray on the ground. Margaret wanted to cover the space with a set of stones, and found what sounded like a quarry. I dutifully drove her 50 miles on Saturday.
I am glad I went. The owner Brad Tracy is a qualified geologist, spent several years in the oil patch, and showed us around his personal museum with rocks from around the world. Flagstone walkways, staurolite crosses, granite boulders – he has a story about just about any rock you can think of from Israel, Italy, Peru and elsewhere. If you find yourself in Lakeland, seek him out for a tutorial on rocks and the history each embeds over the millennia.
And, the selection and prices of the stones Margaret got was excellent. He also stocks a wide range of pine bark, mulch, palms and nursery items. Well worth the drive.
