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 ...
Epithermal systems are geological settings where gold mineralization is associated with volcanic activity. These systems are characterized by the following features: Epithermal gold deposits can vary widely in terms of their size and grade, ranging from small, high-grade veins to ...
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, ...
Continental accretion and plate tectonics are fundamental concepts in geology that help explain the formation and movement of Earth’s continents. Here’s an overview of both concepts: Continental Accretion: Continental accretion is the process by which continents grow in size over ...
Vein deposits are geological formations characterized by the concentration of minerals within distinct fractures or cracks, creating vein-like structures. These deposits play a significant role in the global mining industry, contributing to the extraction of various valuable metals. Understanding the ...
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. ...
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 ...
Placer deposits are natural occurring concentrations of minerals and metals that are found in sedimentary rock formations. These deposits are formed through a series of geological processes that involve the movement, deposition, and alteration of minerals. They are an important ...
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 ...
Based on their Mohs hardness values, the minerals in the list are arranged in order of increasing hardness: 1. Gypsum (2.5) 2. Corundum (7-9) 3. Fluorite (4) 4. Topaz (8) The axe would be able to scrape a line on the gypsum, as it has the lowest hardness value. The axe would also be abRead more
Based on their Mohs hardness values, the minerals in the list are arranged in order of increasing hardness:
1. Gypsum (2.5)
2. Corundum (7-9)
3. Fluorite (4)
4. Topaz (8)
The axe would be able to scrape a line on the gypsum, as it has the lowest hardness value. The axe would also be able to scrape a line on fluorite, as it has a slightly higher hardness value than gypsum. However, the axe would not be able to scrape a line on corundum or topaz, as they have much higher hardness values than both gypsum and fluorite.
