How to calculate Rock Quality Designation
Rock Quality Designation (RQD) is a measure used in geotechnical engineering to assess the quality of rock core samples. It is calculated by measuring the length of intact pieces of rock in a core sample that are longer than 10 cm. RQD stands for “Rock Quality Designation,” and it is ...
Igneous Rock: A Comprehensive Overview
Igneous rock is a category of rock formed through the cooling and solidification of magma, which is molten rock that originates from the Earth’s mantle. This process, known as igneous differentiation, results in the formation of a wide range of rock types, including igneous intrusives and igneous extrusives. Igneous rocks ...
What is Porosity, Types and Causes of Porosity
Porosity Definition Porosity refers to the amount of empty space or voids within a material or substance. It is often expressed as a percentage of the total volume of the material, with the remaining percentage being occupied by the solid material. Porosity can be found in a wide range of ...

What is Dolerite, Properties, and Geological significance
Dolerite is a type of igneous rock that forms through the cooling and solidification of magma. It is a dark-colored rock that typically contains plagioclase feldspar, pyroxene, and amphibole minerals. The name “dolerite” comes from the Greek words “dolos” meaning “poison” and “lithos” meaning “stone,” due to its dark color ...
Metamorphism
The mineralogical, chemical, and structural adjustment of solid rocks to physical and chemical conditions which have generally been imposed at depth below the surface zones of weathering and cementation, and which differ from the conditions under which the rocks in question originated. Metamorphism means to “change form,”. In other words, ...
