There are both similarities and differences between the crystal structures and crystal chemistry of quartz, α-FePO4 and β-FePO4. One of the observed differences is that when the quartz is present at different temperatures. The α-FePO4 phase when present at low temperatures, tend towards the values obtained for β-FePO4 at high temperature. In addition, this case is true for all α quartz when at low temperature, in that it will tend to the values obtained for its respective β quartz experienced at…

A mineral is defined by geologists as naturally occurring, generally inorganic, solid substances, with an orderly crystalline structure, and a definite chemical composition that allows for some variation. The following are examples of materials and whether or not they fit the definition of a mineral. Window glass is a non-crystalline solid that is synthetically created from silica, generally used for its optical transparency. Glass is an inorganic solid with a definite chemical composition.…

going to feed cattle and hogs. Petroleum, sand and gravel, clays for bricks, tiles, and pottery are also important resources. Two thirds of the High Plains Aquifer lie under Nebraska. Nebraska may have more underground water than any other state. The mineral resources in Nebraska are scarce. There is petroleum, natural gas, sand, gravel, limestone, and distinct types of clays. Another resource of Nebraska, is the state flower, goldenrod. All…

Dear Principal, Hot for lava and hard for beds! We should be allowed to take a trip to the Lava Beds. The Lava Beds are located in northeastern California and are the largest formed from volcano eruptions. It is also known as California’s “best kept secret” because of its location. We should go to the Lava Beds because of education, features, exercise and leisure. A visit to the lava beds would provide a significant history lesson. The history, landscape, and findings would be beneficial to…

On Saturday, November the 21st, I visited the Gypsum mine with my lab group: Luke Petro, Liz Morehead, and Kylie Hoef, along with several other groups. After procuring the necessary tools from the geology lab like a meter stick, rock hammer, flashlight, bottle of acid, and helmet, we set off to the mine. Located roughly 100 feet below the surface near Grand Rapids, the mine is now a storage facility owned by Michigan Natural Storage. In the mine, we measured the various rock columns to find how…

Introduction Silver, like gold, is found in a native state; frequently too it occurs as an alloy containing gold, which is recognized, when the silver is dissolved in nitric acid, as the black sediment or oxide of gold. Arsenic and antimony are found also alloyed with it. Several of the ores of lead and copper contain silver. As silver is a precious metal often used for coins, its mining has historically often been lucrative. As with other precious metals such as gold, newly discovered deposits…

of the mineral known as chalcedony. It is a banded mineral, which means that the layering of the rock that formed it has caused “bands” of different colors to appear. Many people mistake onyx for a type of agate, which is another type of chalcedony, but where agate has curved bands onyx has parallel bands instead. Onyx is found in nearly every color, though bands of black and white are the most common. When onyx is banded with red it is called sardonyx. While onyx is a fairly common mineral in…

Labradorite has such a mystical appearance, it can seem like such an ordinary looking rock but with just a slight tilt of your head, the most beautiful flashes of colourful light appear. It is no wonder that this mystical appearance has inspired legends and was used in healing potions by the Inuit people of Labrador. As a fashion accessory it’s grey/iridescent color makes it a great item to go with just about any attire. Labradorite Physical Properties What is Labradorite? Labradorite is…

Flotation: To collect the gold, chemicals are added to the slurry to gather it into a concentrate form. The chemicals attach to certain minerals in the slurry and the slurry is then pumped into large tanks known as flotation cells. Air is then added to the bottom of the cells to rise through the slurry picking up the hydrophobic chemicals added earlier. Once it reaches the surface, it creates…
