The chemists' main objection focused on two isotopes of the element neodymium. By measuring the relative abundances of the isotopes in a rock, geochemists can tell whether the rock originated in the mantle lithosphere -- the slice of the North American jelly sandwich that, according to Bird, the Farallon Plate had dragged away. When the chemists checked the neodymium, however, the rocks proclaimed that the mantle lithosphere is very much intact. The evidence was compelling; many of Bird's…

Located in Southern Arizona, Kartchner Caverns stands as a magnificent tribute to the incredible power of water in the creation of Earth’s landforms. This cave is known as a living cave, meaning that formations are still being created within the cavern walls. Inside Kartchner, it is quite moist and humid, both being common characteristics that living caves share. Today, water stick drips and trickles inside the caves, shaping the caverns even more. The cave, now knows as Kartchner Caverns,…

the site itself is giving out radioactive which is from carnotite decays to uranium as the dinosaur bones are deposited with this element because its porous property, thus letting the ground water to passed through it. The Morrison formation have minerals such as hematite, quartz and clay and due to the iron and copper found in the formation, it causes paleosoil, a red-and-mauve-colored mudstone, to form in the middle section. The main event for the Morrison formation is the regression of sea…

Isa orebody. When the oxidation was completed, the depth of the oxidized zone was around 50m from the ground surface (Forrestal, 1990). Cerussite was found as the dominant mineral while zinc was mostly exhausted. The orebodies’ bedded nature remained the same within the oxidized zone but the rocks are filtrated outside the oxidized zone. In addition, this oxidized ore were generally used for ancient production of mining a long…

Mexico is infamous for its vast mining system. With almost 10 billion ounces of silver mined, Mexico is one of the largest exporters of silver. ( Brown 1). Some of the earliest activity dating back as far as the sixteenth century.To date there over 200 mining companies who have projects in mexico. Historically conditions in these mines were have been below the safety standards. In Most cases miners would enter a tunnel not knowing whether they would make it back out. Francisco Mora’s “Mine…

net/mineral/pyrite.aspx Pyrite’s chemical formula is FeS2, which is the same as the much rarer mineral, Marcasite. Even though these two have the same chemical formula, they both crystallize differently, causing them to be classified as different minerals. Sharing the same chemical formula causes these two minerals to be mislabeled, since their physical characteristics are so similar, and the only real way to definitively tell them apart is by complex analysis.…

Chalcopyrite is a copper iron sulfide mineral. Its coloring is metallic brassy to a brown-orange, and on the Mohs scale, it has a hardness of 3.5 to 4. The chemical formula of chalcopyrite is CuFeS2. It is the most commonly occurring copper containing mineral in New Zealand, but it is only created near volcanic areas. On the metaphysical level, chalcopyrite is used for meditation, specifically for opening the third eye chakra (crown chakra), and physical healing. The stone clears any energy…

In 1965, the serpentine rock became California’s state rock; they are abundant in central and northern California. The serpentine rock is a metamorphic rock that forms by the hydration of rocks from the Earth’s mantle; these types of rocks will rise towards the Earth’s surface along fault zones. It can be found in various colors from dark green and brown, to blue with a glossy surface. However, these rocks tend to be slippery and creates a high risk for land slides. Through a series of…

of ore, valuable minerals or other geological resources such as gold, silver, diamond, iron, coal and uranium from mines. Because the process of extraction requires a large amount of capital, mining business is normally done by the government, multinational companies or wealthy business owners. All the resources that need to be extracted are non-renewable as these materials cannot be artificially created nor grown through agricultural process. So, this is the reason why minerals need to be…

10 Nov. 2014 Tara Linehan GEO 101, Physical Geography Crystal Caves of Naica, Mexico In 1794, according to crystalink early prospectors of Chihuahua City discovered the Naica mine. At the base of the hills the prospectors struck a vein of silver. During that time, people’s interest was in silver and gold. In the beginning of the 1900s, the Mexican Revolution caused a switch from gold and silver to lead and zinc, which the mine had plenty of. Revolutionary troops started to demand money from…
