Definition Mafic Rocks: The term “mafic” is derived from “magnesium” and “ferric” (iron), reflecting the high concentrations of these elements in mafic rocks. Mafic rocks are rich in ferromagnesian minerals such as olivine, pyroxene, amphibole, and biotite. They contain a lower percentage of silica (45-55%), which contributes to their characteristic dark color. Examples of mafic […]Table of Contents Toggle Definition1. Mineral Composition
The law of superposition is a fundamental principle in geology and archaeology that states that in a sequence of undisturbed sedimentary rocks or archaeological layers, the oldest layers are at the bottom, and the youngest layers are at the top. This law is based on the observation that sedimentary rocks and archaeological deposits are typically […]
1. Introduction to Engineering Geology Engineering geology is the application of geological science to engineering practice for the purpose of ensuring that geological factors affecting the location, design, construction, operation, and maintenance of engineering works are recognized and accounted for. It plays a critical role in infrastructure development, natural hazard assessment, and environmental protection. 2. […]Table of Contents Toggle 1. Introduction to Engineering Geology

Astro geology, also known as planetary geology, is a fascinating field that focuses on the study of the geology of celestial bodies such as planets, moons, asteroids, and comets. This interdisciplinary science combines principles of geology, astronomy, physics, and chemistry to understand the formation, evolution, and composition of these extraterrestrial objects. The exploration of astrogeology […]
All of the important processes of metamorphism that we are familiar with can be directly related to geological processes caused by plate tectonics. The relationships between plate tectonics and metamorphism are summarized in Figure. Most regional metamorphism takes place within continental crust. While rocks can be metamorphosed at depth in most areas, the potential for metamorphism […]
Yes, there is evidence to suggest that some animals can detect earthquakes or seismic activity before humans can. Several anecdotal reports and scientific studies have documented unusual behavior in animals prior to earthquakes. Here are a few examples:
Dogs: Dogs have been known to exhibit restless behavior, barking excessively, or trying to escape or hide before an earthquake. It is believed that their acute hearing and ability to detect subtle changes in the environment may enable them to sense seismic waves or other precursors to earthquakes.
Birds: Birds are highly sensitive to changes in their surroundings, including seismic activity. There have been reports of birds flying erratically or behaving unusually before an earthquake. It is thought that they may detect the low-frequency sound or changes in the Earth’s magnetic field associated with earthquakes.
Elephants: Elephants are known to exhibit agitated behavior or try to move away from an area before an earthquake. Their ability to detect seismic vibrations through their sensitive feet and trunk, as well as their keen hearing, may contribute to their ability to sense impending earthquakes.
Fish: Some studies have suggested that fish can display unusual swimming patterns or surface movements prior to an earthquake. It is believed that they may be responding to changes in water chemistry or pressure caused by seismic activity.
While these observations suggest that animals can sense impending earthquakes, the mechanisms by which they do so are not yet fully understood. It’s important to note that not all animals exhibit such behavior before earthquakes, and there is still ongoing research to better understand this phenomenon
