How long will a nice quartz (battery-powered) wall clock last? If it runs on C batteries, what is the bestbrand to get for a clock? How often will I need to change the batteries? Thanks.
It's the most abundant mineral on the planet, so you'll find it in nearly all sedimentary rocks, as well as many igneous rocks. In metamorphic rocks, it's usually been metamorphosed into quartzite.
This is one of the most abundant minerals on the surface. You can find it in igneous, metamorphic and sedimentary rocks in nearly any location in the world. There are less common in the ocean. Types of quartz: Amethyst, Aventurine, Citrine, Carnelian, Herkimer Diamonds, Jasper, Onyx, Rose Quartz, Rutilated Quartz, Smoky Quartz and Tourmalinated Quartz. Rocks include Quartzite - metamorphic Sandstone - Sedimentary Granites- igneous Nearly every type sedimentary, igneous and metamorphic rock contains quartz in one form or another and of varying concentrations. It is essential in the formation of most igneous rocks, including Granites, granodiorites, rhyolites. The weathering of igneous rocks removes most other minerals but Quartz grains resist the erosion process, collect together and when compressed make Sedimentary formations. When Sedimentary rocks containing Quartz enter a Metamorphic process, the Quartz grain sizes change greatly. Quartz crystals, of many forms, also make up the lining found in Geodes.
