Branches and Specializations in Geology A. Mineralogy B. Petrology C. Paleontology D. Structural Geology E. Geophysics F. Geochemistry 2. Processes Studied in Geology ...

    Oceanic Crust and Continental Crust: The difference

    The Earth’s crust is divided into two major types: oceanic crust and continental crust. These two types of crust differ significantly in composition, structure, thickness, and other physical and chemical properties. Understanding the differences between oceanic and continental crust is fundamental to geology, as it helps explain various geological processes, ...

    What types of rocks found Gold

    Gold is typically found in the following types of rocks: 1. Quartz Veins Gold is found in quartz veins through a combination of geological processes involving hydrothermal fluids, which transport and deposit gold and other minerals. Here’s a detailed explanation of how gold ends up in quartz veins: 1. Formation ...

    Mafic vs. Felsic: A Comprehensive Comparison

    Definition Mafic Rocks: The term “mafic” is derived from “magnesium” and “ferric” (iron), reflecting the high concentrations of these elements in mafic rocks. Mafic rocks are rich in ferromagnesian minerals such as olivine, pyroxene, amphibole, and biotite. They contain a lower percentage of silica (45-55%), which contributes to their characteristic ...

    Atterberg Limits: Essential Metrics for Soil Classification and Engineering

    Introduction Atterberg Limits are crucial parameters in geotechnical engineering and soil science that characterize the physical state and behavior of fine-grained soils, particularly clays. Developed by Swedish chemist Albert Atterberg in the early 20th century, these limits provide insight into how soil behaves under varying moisture conditions. Understanding Atterberg Limits ...

    Cone Penetration Test (CPT)

    The Cone Penetration Test (CPT) is a widely used in-situ testing method in geotechnical engineering for determining the geotechnical properties of soils. The CPT provides continuous or semi-continuous data on soil stratigraphy and properties such as soil type, relative density, shear strength, and other parameters relevant to foundation design and ...

    Piping Effect in Geotechnical Engineering

    Introduction Piping is a phenomenon in geotechnical engineering where subsurface erosion occurs, leading to the formation of channels or pipes within soil. This can result in significant structural failures, especially in embankments, dams, and levees. Understanding the causes, effects, and mitigation strategies for piping is crucial for ensuring the stability ...

    What is Cinnabar

    ✳️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 ...

    Kimberlite

    🔷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 ...

    Geological Time Scale

    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: ...

    What are Rare Earth Elements and why are they important?

    What are Rare Earths?  The Japanese call them “the seeds of technology.”  The US Department of Energy calls them “technology metals.”  They make possible the high tech world we live in today – everything from the miniaturization of electronics, to the enabling of green energy and medical technologies, to supporting a myriad of ...

    Geology 101

    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 ...

    What is an Unconformity in Geology

    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 ...

    Mineral

    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 ...
