Banded iron formation
Banded iron formations of the Great Lakes region and the Frere Formation of western Australia are somewhat different in character and are sometimes described as granular iron formations or GIFs. Their iron sediments are granular to oolitic in character, forming discrete grains about a millimeter in diameter, and they lack microbanding in their chert mesobands.

Compressive Strength (UCS) test. The UCS (σ c) of the intact rock is used in rock mass classifiion schemes (section ), and as a basic parameter in the rock mass strength criterion. These tests are usually done on cylindrical samples (Jager and Ryder, 1999). It is used to determine the unconfined compressive strength (σ c

compressive strength
Compressive Strength Instron. The compressive strength of a material that fails by shattering fracture can be defined within fairly narrow limits as an independent property. However, the compressive strength of materials that do not shatter in compression must be defined as the amount of stress required to distort the material an arbitrary ...

Abstract. At Golden Cross, andesitic lavas and volcaniclastic rocks host epithermal veins that formed in the shallow part (<500 m depth) of a hydrothermal system. Calcite is a trace mineral in precious metalbearing quartz veins and a common replacement mineral in the surrounding intensely altered host rocks.
