Mohs hardness scale The Mohs hardness scale is a qualitative scale used to measure the scratch resistance of various minerals or materials. It was developed by Friedrich Mohs, a German mineralogist, in 1812. The scale ranges from 1 to 10, with 1 being the softest and 10 being the hardest. Each mineral on the Mohs […]Table of Contents Toggle Mohs hardness scale
Bismuth: A Detailed Exploration for Geology Students Bismuth (Bi), one of the heaviest stable elements, is an intriguing metal that possesses unique physical and chemical properties. While it is not as widely known as other metals like iron or copper, bismuth has become increasingly significant in various industrial applications, particularly as a non-toxic alternative to […]Table of Contents Toggle Bismuth: A Detailed Exploration for Geology ...
Rock Quality Designation (RQD) is a measure used in geotechnical engineering to assess the quality of rock core samples. It is calculated by measuring the length of intact pieces of rock in a core sample that are longer than 10 cm. RQD stands for “Rock Quality Designation,” and it is a measure used in geology […](adsbygoogle = window.adsbygoogle || []).push({});
The mineralogical, chemical, and structural adjustment of solid rocks to physical and chemical conditions which have generally been imposed at depth below the surface zones of weathering and cementation, and which differ from the conditions under which the rocks in question originated. Metamorphism means to “change form,”. In other words, metamorphism is a process that […]Table of Contents Toggle Process of Metamorphism
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 of Hydrothermal Fluids 2. Movement […]Table of Contents Toggle 1. Quartz Veins
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 edge of the compass against the plane of the outcrop. Sometimes it is easier to […]Table of Contents Toggle What is Strike?Measuring ...
Angola is a country located in Southern Africa, with a diverse geological history. The formation of Angola’s geology can be traced back to the Precambrian era, which lasted from around 570 to 635 million years ago. Geology of Angola During this time, the continent of Gondwana began to break apart, forming the modern-day African continent. […]Table of Contents Toggle Geology of Angola
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 helps engineers and scientists classify […]Table of Contents Toggle Introduction
Over geologic time, if oil deposits are not extracted, natural processes like biodegradation, chemical changes, migration, and pressure variations occur. Microorganisms may break down hydrocarbons, altering oil composition. Oil may migrate within the reservoir, and heavier, more viscous components can remain. Pressure and temperature changes, along with diagenesis and catagenesis, influence the physical state and characteristics of the oil. Ultimately, if left untouched, oil deposits undergo complex transformations, impacting their original composition and distribution.
