When we think about tunneling, we often picture massive machines and skilled laborers hard at work underground. While these elements are undoubtedly essential, there’s an unsung hero behind every successful tunneling project: the geologist. In this article, we’ll explore the ...
In geology, joints are fractures or cracks in rocks along which there has been no significant movement parallel to the fracture surface. These fractures are typically a result of stress within the Earth’s crust and occur due to various geological ...
Metamorphic rocks are classified based on their texture, mineralogy, and composition. The facies classification of metamorphic rocks is based on the conditions of temperature and pressure under which the rock formed. The following are the facies classification of metamorphic rocks: ...
Andesite: A Comprehensive Guide Andesite, derived from the Andes Mountains in South America, is an igneous rock that holds a significant place in the geological world. Its composition, formation, and various uses make it a fascinating subject for study. In ...
Continental accretion and plate tectonics are fundamental concepts in geology that help explain the formation and movement of Earth’s continents. Here’s an overview of both concepts: Continental Accretion: Continental accretion is the process by which continents grow in size over ...

Dolerite is a dark, igneous rock with a medium-grained texture that is composed primarily of plagioclase feldspar, pyroxene, and sometimes olivine. Some of the key features of dolerite are:
Color: Dolerite is typically dark-colored, ranging from black to dark gray.
Texture: It has a medium-grained texture, which means that the individual mineral grains are visible to the naked eye.
Hardness: Dolerite is a hard rock, with a Mohs hardness of around 6-7.
Density: Dolerite has a relatively high density, typically ranging from 2.8 to 3.0 g/cm3.
Composition: Dolerite is primarily composed of plagioclase feldspar, pyroxene, and sometimes olivine. It may also contain other minerals such as quartz, biotite, or hornblende.
Occurrence: Dolerite is a common rock type found in many parts of the world, including parts of Africa, Australia, Europe, and North America. It is often found in dykes and sills, and may also form large intrusive bodies known as plutons.
Uses: Dolerite is a popular building stone and is often used as an aggregate in road construction. It is also used in the construction of monuments, as a decorative stone, and as a source of crushed rock for various industrial processes.
