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, ...
Geologic strata, also known as rock layers or rock formations, are the result of the sedimentation, deposition, and cementation of minerals, rocks, and other Earth materials over millions of years. These strata provide a window into Earth’s geological history, revealing ...
Mississippi Valley-Type (MVT) Deposits: Unveiling the Secrets of Shallow Marine Mineralization Introduction: Mississippi Valley-Type (MVT) deposits stand as unique geological formations, characterized by the accumulation of lead and zinc minerals in shallow marine settings. Named after the prolific occurrences in ...
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 ...
A Comparison of Two Related Fields Geology and geography are two interconnected fields of study that focus on the Earth and its various features. While geology is concerned with the composition, structure, and processes of the Earth, geography is more ...
Poly-metallic vein deposits are geological formations that contain multiple metals in economically viable concentrations. These deposits play a crucial role in the global mining industry, contributing to the extraction of various valuable metals. Understanding the formation, characteristics, and extraction methods ...
An ophiolite is a section of oceanic crust and upper mantle that has been uplifted and exposed above sea level due to tectonic processes. Ophiolites are important geological features because they provide a window into the Earth’s interior and allow ...
Skarn Deposits: Unraveling the Geological Marvel Skarn deposits, also known as skarns, represent a fascinating geological phenomenon formed through the interaction of hot fluids from intrusive igneous bodies with carbonate-rich sedimentary rocks. In this comprehensive guide, we’ll explore the various ...

Ductile deformation, also known as plastic deformation, refers to the process by which rocks or other materials change shape without breaking or fracturing. This type of deformation occurs under high pressure and temperature conditions, typically deep within the Earth’s crust. During ductile deformation, rocks undergo a gradual and continuous change in shape due to the rearrangement of their mineral grains.
Under extreme pressure and temperature, minerals within the rocks can change their crystal structure, allowing them to flow and stretch without breaking. This behavior is similar to the way that plastic materials, like clay or putty, can be molded and deformed without immediately shattering.
Ductile deformation often results in features such as folding and stretching of rock layers, and it’s common in regions where tectonic forces are actively shaping the Earth’s crust, such as mountain-building processes. This is in contrast to brittle deformation, where rocks break and fracture due to intense stress without undergoing significant plastic deformation
