Geology 101 is the study of the Earth and its materials, structures, processes, and history. It is a broad field that encompasses many different disciplines, including mineralogy, petrology, paleontology, and geophysics. Geologists study the Earth’s physical features, including its rocks, ...
What is VMS? Assemblages of mostly sulfide minerals that develop on the seafloor at locations of concentrated hydrothermal discharge, relates to a kind of ore deposit that’s mined from existing oceanic crust formed underwater are Volcanogenic Massive Sulfides (VMS) Deposit. ...
Introduction: Non-metallic miner als, also known as non-metals, are a diverse group of elements that do not possess metallic properties. They are soft, brittle, and generally have low melting and boiling points. Non-metallic minerals play a vital role in the ...
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 ...
Epithermal systems are geological settings where gold mineralization is associated with volcanic activity. These systems are characterized by the following features: Epithermal gold deposits can vary widely in terms of their size and grade, ranging from small, high-grade veins to ...
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 ...
Introduction: Sedimentary Exhalative (SEDEX) deposits stand as intriguing geological formations, offering a glimpse into the subaqueous processes that shape the Earth’s crust. These deposits, characterized by the accumulation of minerals in marine sedimentary basins, play a significant role in the ...
There are several sampling techniques used in mineral exploration and mining, depending on the nature and characteristics of the deposit. Some of the most common techniques include: Ultimately, the choice of sampling technique will depend on the specific objectives of ...
Mohs hardness scale The Mohs hardness scale is a qualitative scale used to measure the scratch resistance of various minerals or materials. It was developed by Friedrich Mohs, a German mineralogist, in 1812. The scale ranges from 1 to 10, ...
What is geology definition? Geology is the scientific study of the Earth, its rocks, minerals, and the processes that shape it. It is a branch of Earth science that focuses on understanding the Earth’s history, structure, and the processes that ...
The mantle of the Earth is not entirely molten because of the high pressure that exists in the Earth's interior. While the temperatures in the mantle are high enough to melt rock, the immense pressure from the overlying rock layers prevents the mantle from fully melting. This phenomenon is known asRead more
The mantle of the Earth is not entirely molten because of the high pressure that exists in the Earth’s interior. While the temperatures in the mantle are high enough to melt rock, the immense pressure from the overlying rock layers prevents the mantle from fully melting. This phenomenon is known as “pressure melting.” As a result, the mantle exists in a semi-solid state, with some regions experiencing partial melting while others remain solid. This unique state of the mantle allows for the movement of solid rock over long periods, contributing to the geological processes that shape the Earth’s surface.
