Granite on Mars?|
November 20, 2013 | Georgia Tech
“Researchers now have stronger evidence of granite on Mars and a new theory for how the granite – an igneous rock common on Earth — could have formed there. The findings suggest a much more geologically complex Mars than previously believed.” Quoted from the Georgia Tech press release.

Mineral Hardness Picks|
November 17, 2013 | Geology.com Store
Mineral hardness picks are pencil-like tools that have points made from materials that match the hardness of minerals in the Mohs Hardness Scale. With them you can easily test the hardness of mineral grains in a rock and test the hardness of small-size specimens. In our opinion they are easier to use than pieces of minerals and allow you to obtain more accurate results.
Provenance of Obsidian Artifacts|
November 12, 2013 | Columbus Dispatch
Ancient people carried and traded obsidian objects over wide geographic areas. Researchers have found success at attributing these artifacts with the geographic locality of an eruption by measuring their magnetic characteristics.

Mapping the Pirate Fault|
September 17, 2013 | Arizona Geological Survey
“The 25 km accessible trace of the Pirate fault has been mapped to locate and describe those erosionally exhumed remnants of the fault that together provide a basis for structural reconstruction of this nominally Basin-Range tectonic feature. The fault forms the western boundary of the Santa Catalina Mountains in southeastern Arizona, where it separates the uplifted Santa Catalina structural block on the east from the down-dropped, alluvial Cañada del Oro basin on the west.” Quoted from the Arizona Geological Survey publication release.
