OLYMPIC CURLING STONES MADE FROM SPECIAL GRANITE The United States won its first-ever Olympic Gold Medal in the sport of curling at the 2018 Winter Olympics. This brought attention to the use of granite in manufacturing the curling stones, also known as "rocks," used to play this sport. Curling stones weigh between 38 and 44 pounds and are made from granites with special physical properties. WHAT IS MARIPOSITE? IS IT A ROCK? IS IT A MINERAL? Mariposite is an informal name that has been used for green micas. It is also an informal name used for rocks containing green micas, quartz, carbonates, and other minerals that were altered by AUSTRALIA OIL SHALE DEPOSITS The oil-shale deposits of Australia range from small and noneconomic to deposits large enough for commercial development. The "demonstrated" oil-shale resources of Australia total 58 billion tons, from which about 3.1 billion tons of oil (24 billion barrels) is recoverable (Crisp and others, 1987, p. 1).

MAP OF THE MIDDLE EAST AND SURROUNDING LANDS The Middle East is a geographical region that, to many people in the United States, refers to the Arabian Peninsula and lands bordering the easternmost part of the Mediterranean Sea, the northernmost part of the Red Sea, and the Persian Gulf. GREEN DIAMONDS: A VERY RARE AND VERY VALUABLE DIAMOND COLOR Green Diamond: This green diamond has all of the characteristics of a highly desirable colored diamond: A) it is a natural diamond; B) the green color was produced by nature; and, C) the color is a pure green with a rich saturation. The Gemological Institute of America graded its color as “Fancy Vivid green” with a natural origin and an even

distribution.

PEGMATITE: IGNEOUS ROCK Crabtree pegmatite: One of the most interesting pegmatites is the Crabtree Pegmatite of western North Carolina. It is a granitic pegmatite that intrudes the boundary between two rock units in a dike that is up to two meters wide. It was mined for emeralds by a series of owners, which included Tiffany and Company, between 1894 and the

1990s.

WHO OWNS THE ARCTIC OCEAN? An Energy and Mineral Resource Treasure. Who owns the Arctic Ocean and any resources that might be found beneath those waters? This question has enormous economic significance. The United States Geological Survey estimates that up to 25% of the world's remaining oil and natural gas resource might be held within the seafloor of the Arctic

Region.

HOW TO PAN GOLD: INSTRUCTIONS & TECHNIQUES FOR GOLD PANNING The best way to learn about panning for gold is to observe the techniques of successful panners. Although the methods of these four panners are not identical, they share two common goals: get the heavy gold particles to settle to the bottom of the pan by vigorously shaking the sediment-water mixture DOWSING AND WATER WITCHING: METHODS OF FINDING GROUNDWATER? "Dowsing," "water witching," "divining," and "doodlebugging" are all names for the practice of locating groundwater by walking the surface of a property while holding a forked stick, a pair of L-shaped rods, a pendulum, or another tool that responds when the person moves above a
