I like the concept of heating only the room being used. I have a space heater but am not satisfied with it's performance. I've read promotional litearture on the quartz infrared portable heaters and I like what I hear. It sounds like just what I'm looking for. Any information, pro or con would be greatly appreciated
Quartz is the most common mineral. It is also very durable at the earths surface. The easiest way to mine it would be to go to the beach with a bucket and spade. If the sand is a yellow colour, it will be quartz; all the less durable minerals will have weathered or eroded away. If it is a quartz crystal you are looking to mine, try hitting the rock around it with a hammer. Stone age man found that the quartz (in the form of flint) was easy to mine from chalk).
That is a hard question to answer, It depends on what kind of deposit you are talking about. If you are talking about Crystals, they are sedimentary, the silica is dissolved in water as it percolates through mafic rock, then the dissolved silica is deposited when the water reaches a surface and is able to sit long enough for the silica to crystallize. Most of the continental crust has a high silica content and rock quartz is just an igneous body. Granit, Sandstone, and even Limestone (among many otheres) can all contain Quartz, but in the end its origins like most minerals is igneous.
Some deposits are water related such as geothermal. Maybe you can look up MT. Ida Arkansas near Hot Springs. There is a crystal mine there you can go to. It's called Coleman's Other than that try Rock Gem magazine on the net. Good luck
