Color Varieties of the Mineral Quartz
You may wish to print a copy of the lecture outline (minus the illustrations) and you have two options:
"Minerals can be only be identified absolutely by x-ray analysis and chemical tests. The x-ray analysis determines the structure of the mineral and the chemical tests determine the composition of the mineral. Structure and composition are the defining marks of a mineral. Unfortunately for the average collector, these tests require expensive equipment, expert know-how and often destroy the specimen. Fortunately, both structure and composition affect certain physical properties. It is through the proper use of these properties that minerals can reliably be identified."
This resource is one of a number of lectures from a one semester course taught at the University of Wisconsin. You might want to spend some time looking at the format and requirements for the course. Are you ready to take a course which is only offered via the Internet?
"WebElements colour codes the elements according to the periodic table block within each occurs. Unfortunately, some browser programs are not capable of displaying the colours. "
"Welcome to recreational gold prospectors everywhere and to those who are interested in recreational gold mining and prospecting. You won't dig up any gold nuggets here but you may find some useful "nuggets" of information. Those interested in finding coins, artifacts and other things with a metal detector are directed to the Worldwide Treasure Links page. If you are a rockhound or mineral collector, try the Rock Hound Information Page."
