✳️Cinnabar is a toxic mercury sulfide mineral with a chemical composition of HgS. 🔷It is the only important ore of mercury. It has a bright red color that has caused people to use it as a pigment, and carve it into jewelry and ornaments for thousands of years in many parts of the world. Its […]
🔷Kimberlites, named after the town of Kimberly, South Africa, where they were first described, are volcanic rocks that originate in Earth’s mantle.🔷They are mined exclusively for diamonds. The photo shows the “Big Hole” at Kimberly.🔷The Hole was mined from 1871 to 1914 and reached a depth of 240 m below the surface. Subsequently it filled […]
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 history. The time scale is divided into four main parts: Eons, Eras, Periods, and Epochs.

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, minerals, soils, and water. They also study the Earth’s internal structure and the processes that […] Table of Contents Toggle Why Study Geology?What Do GEOSCIENTISTS ...

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 sediment is deposited on top of them. There are three types of unconformities: Disconformities A […] Table of Contents Toggle There are three types of unconformities:
Minerals are homogeneous, naturally occurring, inorganic solids that have a definite crystalline structure and chemical composition. In 1995, the World Minerals Organization put another definition saying that “a mineral is an element or a chemical compound that is naturally crystalline and formed as a result of geological processes.”Minerals have their own specific physical properties which […] Table of Contents Toggle Minerals are classified according to their chemical composition.
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 have distinct physical properties. Each substance has a known atomic structure and a fixed chemical […] Table of Contents Toggle MineralsOres materialsMetals

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.
