Mineral Hardness Picks
April 10, 2014 | 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. They also do not contaminate your specimen with particles of the hardness mineral.

Mineral Rights
April 17, 2014 |
In most countries all mineral resources belong to the government. This includes all valuable rocks, minerals, oil or gas found on or within the Earth. In the United States ownership of mineral resources was originally granted to the individuals or organizations that owned the surface. These property owners had both "surface rights" and "mineral rights". Since then the owners have enjoyed the freedom to sell, lease, gift or bequest these rights individually or entirely to others. Now a single plot of land on the surface can have several different subsurface owners!

Frac Sand Production Keeps Rising
March 23, 2014 |
An estimated 32 million tons of frac sand was produced by United States quarries during 2013. That is over a 300% increase in production over the 2009 tonnage. Frac sand is used as a proppant in the hydraulic fracturing process used to increase the production of oil and gas wells drilled in shale and other tight formations.
