Where Is the Utica Shale?
June 26 | Geology.com
The cross section above shows the subsurface position of the Marcellus Shale, Utica Shale and the continental basement rock. The line of cross section is shown as line A-B on the inset map. Note that the Utica Shale is about 2000 feet below the Marcellus under eastern Ohio but about 6000 feet below the Marcellus in south-central Pennsylvania. Also note that the Marcellus Shale potential source rock does not extend as far into Ohio as the Utica.

Many Water Cycle Diagrams Promote Misconceptions
June 24 | EOS Earth & Space Science News
If you are going to create a "water cycle" diagram for elementary students, it must be simple because students have not yet developed the content knowledge and analytical abilities to understand the full complexity. Give students a few years and visit the water cycle again, this time adding a couple more variables that their new level of abilities can appreciate. Visiting the water cycle multiple times during a K-12 education will help students appreciate that some topics are complex, but they can be understood if taken one-step-at-a-time.
Every introductory course in geology at the college level can be followed by one or more upper level courses that go into more detail and clearly demonstrate that the introductory material was oversimplification. Tell students that they are obtaining a deeper understanding. This is part of a quality educational experience and is what develops a geological maturity of the person. This is not unique to the water cycle.
Perhaps we should have a set of water cycle diagrams that can be used in a sequence, through a K-12 education, and a set that can be used in college courses to demonstrate further complexity in a single lecture, or in a diverse sequence of courses across the undergraduate experience.

Mineral Rights: Basic Information About Mineral, Surface, Oil and Gas Rights
June 23 | Geology.com
"Mineral Rights" entitle a person or organization to explore and produce the rocks, minerals, oil and gas found at or below the surface of a tract of land. The owner of mineral rights can sell, lease, gift or bequest them to others individually or entirely. For example, it is possible to sell or lease rights to all mineral commodities beneath a property and retain rights to the surface. It is also possible to sell the rights to a specific rock unit (such as the Pittsburgh Coal Seam) or sell the rights to a specific mineral commodity (such as limestone).

U-Pb Ages of Zircon Inclusions in Sapphires and Implications for Geographic Origin
June 6 | Gemological Institute of America
The geographic origin of blue sapphire can significantly affect its value. Researchers are exploring the use of geochemistry, inclusions and zircon dating to assist in determining their geographic origin.

Moldavite: A Green Glass (and Gem Material) Formed by an Ancient Asteroid Impact
June 5 | Geology.com
Moldavite Through a Microscope: In this photograph you are looking into a faceted moldavite through its pavilion facets. The large dark rounded inclusion that looks like a doughnut is an air bubble trapped in the moldavite. The smaller, dark, rounded inclusions are smaller bubbles. The chaos of streaks and swirls that pass through this view are flow lines in the moldavite. These are evidence that the molten material which solidified to form this moldavite was in chaotic motion immediately before solidification.
The bubbles and flow lines are two of the three important microscopic characteristics needed to make a positive identification as "moldavite." The third characteristic for identification is inclusions of lechatelierite. The high-relief, lens-shaped features in the moldavite at top left, lower right, and lower center are probably lechatelierite; as is the high-relief snake-like feature in lower center. This specimen is most likely moldavite, but submission to a professional gem laboratory is needed for a positive identification.
