rock specimen core Solutions Just Right For You

Geodes are like the Tootsie Roll Pop of the geology world because underneath the hard exterior lies a surprise center! Hollow Rocks So let's start at the beginning how do you get a hollow rock with lots of sparkling crystals inside? First you need a hollow rock Geodes start their lives as a hollow bubble inside a layer of rock The bubble could be from air inside explosive volcanic rock THE INTERRELATIONSHIP AMONG THE ROCK TYPES IS REFERRED TO AS THE ROCK CYCLE THERE ARE FOUR MAIN LAYERS THAT MAKE UP THE EARTH 1 Inner Core - A mass of iron with a temperature of about 7000 degrees F Although such temperatures would normally melt iron immense pressure on it keeps it in a solid form The inner core is approximately 1 500 miles in diameter 2 Outer Core

This beautiful specimen of silver ore comes from the country of Peru in South America The dark colored minerals are the ones which are silver bearing while the red and pink colored crystals are Rhodochrosite a common manganese mineral that is found in a number of silver ores Standard Types of Silver Ores There are two general classes of silver ore that have been mined 1) lead-silver and

The Unconfined Compression Test is a laboratory test used to derive the Unconfirmed Compressive Strength (UCS) of a rock specimen Unconfirmed Compressive Strength (UCS) stands for the maximum axial compressive stress that a specimen can bear under zero confining stress Due to the fact that stress is applied along the longitudinal axis the Unconfined Compression Test is also known as

A triaxial shear test is a common method to measure the mechanical properties of many deformable solids especially soil (e g sand clay) and rock and other granular materials or powders There are several variations on the test In a triaxial shear test stress is applied to a sample of the material being tested in a way which results in stresses along one axis being different from the
