Meteorites

  1. 3. It can be photographed from space!
  2. 5. METEORITES: <ul><li>VALUE? </li></ul><ul><li>TYPES? </li></ul><ul><li>How do Meteorite Hunters find them ? </li></ul>
  3. 6. First… The types of meteorites.
  4. 8. There are 3 Basic Types: <ul><li>STONY </li></ul><ul><li>IRON </li></ul><ul><li>STONY-IRON </li></ul>Photos – Encyclopedia Britannica
  5. 9. Stony Meteorites: <ul><li>Most common type. </li></ul><ul><li>Makes up 90% of all falls. </li></ul><ul><li>Two Sub-Categories: Chondrites, and Achondrites. </li></ul><ul><li>One variety of Chondrite contains carbon compounds which scientists believe might have been the precursors of life on Earth. </li></ul>Photo – Encyclopedia Britannica
  6. 10. Iron Meteorites: <ul><li>Made up of crystalline iron-nickle allloy. </li></ul><ul><li>Make up only 5% of all falls. </li></ul><ul><li>Similar to Earth’s metallic core. </li></ul>Photo – Encyclopedia Britannica
  7. 11. Stony-Iron Meteorites: <ul><li>Made up of iron-nickle alloy </li></ul><ul><li>& non-metallics mineral matter. </li></ul><ul><li>Makes up 5% of all falls. </li></ul><ul><li>Similar to where Earth’s core meets </li></ul><ul><li>the mantle. </li></ul>Photo – Encyclopedia Britannica
  8. 12. Next… The value of meteorites.
  9. 14. The chemical make-up affects the value : A scanning-electron-microscope photograph of pyroxene and plagioclase crystals (the long and the short crystals, respectively) that grew in a cavity in a fragment of Moon rock gathered during the Apollo 14 mission. – Encyclopedia Britannica - NASA
  10. 15. Value is affected by how Abundant or Rare the meteorite is. <ul><li>Meteorite weather and breakdown, and iron rusts. These types are relatively inexpensive and readily available. </li></ul><ul><li>A Chondrite price could range $5 to $15 per gram. </li></ul><ul><li>Some meteorites are worth more than gold! </li></ul>
  11. 17. Value is affected by how Abundant or Rare the meteorite is. <ul><li>When Mars and Moon meteorites turn up dealers and collectors worldwide quickly buy them up. The prices are truly astronomical; </li></ul>Mars photo – Encyclopedia Britannica Moon photo – Encyclopedia Britannica $2,500 to $3,000 per gram!
  12. 18. It is extremely rare that a meteorite hits a man made object! <ul><li>1984 Georgia meteorite hits a mailbox. </li></ul><ul><li>1992 Peekskill meteorite hits car. </li></ul>Sold for how much? (Car currently for sale)
  13. 19. Finally… The proven methods utilized by Meteorite Hunters to find meteorites.
  14. 20. Where, how, and with what tools do Meteorite Hunters search for their treasures?
  15. 21. Where exactly do they search? <ul><li>Searching a known strewn field , with plotted maps help locate additional pieces scattered over dozens of miles. </li></ul><ul><li>Using eyewitness accounts or video of falling meteorites can help narrow a search. </li></ul>
  16. 22. What tools do the hunters use? <ul><li>Metal detector </li></ul><ul><li>High powered magnet </li></ul><ul><li>Other tools that might be useful are : snake boots, long pants, sunscreen, gloves, a map, a GPS, and patience. </li></ul>
  17. 23. METEORITES: <ul><li>High VALUE </li></ul><ul><li>3 Basic TYPES </li></ul><ul><li>Proven methods utilized </li></ul><ul><li>by Meteorite Hunters </li></ul>
  18. 25. Giant Rocks from space!
  19. 26. Giant Rocks from space!
  20. 27. Giant Rocks from space!
