M ara Saunders Nickel and Cobalt Nickel and cobalt were mined at the ocean floors by ocean miners These miners had to go down 40006000m in the ocean Nickel is used for well nickels and Cobalt is used for fuel Nickel has a silverywhite luster and a metallic gray color Then Cobalt has a reddishsilver white color metallic luster and a grayish black streak . A homogenous, naturally occurring substance with definable internal structure is called mineral. .. Mode of occurrence of minerals:. (1) In igneous and metamorphic rocks: The smaller occurrences are called veins and the larger occurrences are called lodes. They are usually formed when minerals in liquid/molten and gaseous forms are forced upwards through cavities towards the earth’s surface. Examples: tin, copper, zinc, lead, etc.. Geologists use characteristics to tell one mineral from another. What is a Mineral?. Must be a solid.. Must occur in nature.. Must have a definable chemical composition (. NaCl. ).. Must have a crystalline structure.. Eccleston. George Shires. Christopher Houston. Sizing Up Shale States. A Comparison of Mineral Law in Ohio, Pennsylvania, and North Dakota.
