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. ...
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, ...
Introduction: Mining geology is the cornerstone of successful mineral exploration and extraction. It’s a specialized field that combines geological expertise with a keen understanding of the Earth’s resources. In this comprehensive guide, we’ll delve into the world of mining geology, ...
Bowen’s series reaction is a model that describes the crystallization of minerals from a magma. It was developed by the American petrologist Norman L. Bowen in the early 1900s. According to the Bowen’s series reaction, minerals crystallize from a cooling ...
In engineering and geology, a fault is a fracture or discontinuity in the Earth’s crust where movement or displacement has occurred. Types of faults Causes of Fault The causes of faults are diverse and depend on the type of fault. ...
An unconformity is a surface of erosion or non-deposition that separates two rock units that have different ages. It represents a time gap in the geologic record, and it occurs when sedimentary rocks are tilted, uplifted, and eroded before new ...
Earth science or geoscience 地球科学 is a broad field of study that encompasses various scientific disciplines related to the Earth and its processes. It includes the study of the Earth’s composition, structure, processes, and interactions with its atmosphere, hydrosphere, and ...
Geological Time Scale The geological time scale is a system of chronological measurement that relates geological events and geological time to a numerical scale. It is used to describe the timing and relationships between events that have occurred throughout Earth’s ...
What is Strike? The strike is the compass direction of a line marking the intersection of an inclined plane with a horizontal plane such as the Earth’s surface. Measuring Strike In order to measure the strike, place the side or ...
Rocks are the building blocks of the Earth’s crust and are fundamental to the field of geology. They provide a window into our planet’s history, revealing clues about its formation, changes over time, and the processes that have shaped it. ...
Magma is molted material consisting of most common elements that form all the minerals (crystals) on Earth's surface while mantle is a part of Earth (largest one in volume). It would be right to say that Earth's mantle is about 3000 km thick layer of molted material (magma) with high concentration oRead more
Magma is molted material consisting of most common elements that form all the minerals (crystals) on Earth’s surface while mantle is a part of Earth (largest one in volume). It would be right to say that Earth’s mantle is about 3000 km thick layer of molted material (magma) with high concentration of Si. There fore, magmatic rocks have so much SiO2 components, whether in form of quartz or other silicatic minerals with SiO2 component. There are many for s of eruption, most of them are caused by certain amount of water falling down to crater, than causing rapid heating where later water steam works as a fuel for volcanic eruption. Them, cooled rocks, lava (magma but outside) and vapor are injected into atmosphere. But, there is that finala, deadliest

Mantle is a largest part of Earth, 3000 km thick. Magma is molted material with high portion of SiO2 conponent. There fore, magmatic rocks are consistrd of si locate minerals. Magma is called lava when om surface. Most eruptions are caused by significant amount of water sliding down to volcanic crater, later when heated working as a fuel for eruption. In such cases, eruption trows rocks, vapor and lava onto surface. But, rearest and deadliest type of eruption is a hot spot eruption. It occurs when there is high concentration of ultramafic magma in a buble (gigant one), much hotter and less dense than sorounding magma. In such casec, eruption brings mostly lava, only small portion of rocks and vapor.
