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, ...
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 ...
Basalt is a dark-colored, dense rock composed primarily of plagioclase feldspar and pyroxene. It is the most common rock type found in oceanic crust and is an important component of the Earth’s continental crust. Basalt is formed through the rapid ...
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 ...
Introduction Engineering geology is a crucial field that plays a pivotal role in various construction and infrastructure projects. It’s the science that bridges the gap between geology and engineering, providing essential insights to ensure the safety and sustainability of construction ...
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 ...
The difference between mineral, metal and ores Many people confuse three completely different classes of substances (minerals, ores, and metals), so that metal becomes a mineral, and all minerals become ores. Minerals Minerals are inorganic solids (elements or compounds) that ...
Soil classification tests are methods of determining the physical and engineering properties of soils, such as moisture content, specific gravity, grain size distribution, Atterberg limits, and shear strength. These tests are important for geotechnical design and construction, as they help ...
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. ...
Unveiling the Mysteries of Igneous Rocks Introduction: Igneous rocks, born from the fiery depths of the Earth, hold a unique place in the geological tapestry. Formed through the solidification of molten magma or lava, these rocks play a pivotal role ...

Pyrite is a type of iron sulfide mineral that forms in a variety of geometric shapes due to its unique crystal structure and formation process. The formation of pyrite can be attributed to the following factors:
1. Crystal structure: Pyrite has a cubic crystal structure, which is characterized by a face-centered cubic (FCC) arrangement of atoms. This structure leads to the formation of six-sided, equilateral pyramids, which are the building blocks of the mineral. These pyramids stack together to create the geometric shapes of pyrite, such as cubes, octahedra, and dodecahedra.
2. Formation process: Pyrite forms through a process called replacement reaction, where it replaces other miner
als in the Earth’s crust. This process often occurs in the presence of water and oxygen, which can promote the formation of pyrite’s distinct geometric shapes.
3. Environmental conditions: Pyrite can form in various environments, including sedimentary, hydrothermal, and oxidized settings. These different environments can influence the size, shape, and arrangement of pyrite crystals, leading to the formation of unique geometric structures.
In summary, the formation of pyrite is geometrical due to its unique crystal structure, the replacement reaction process, and the influence of environmental conditions.
