Crustal abundance
The crust is the outermost layer of the solid Earth and composed of two major types of rocks: the oceanic crust and the continental crust. The abundance of crustal rocks varies with location and depth, but can be measured in parts per million (ppm) or billion (ppb). The continental crust contains ......
Frozen ground survey
Introduction
Frozen soil engineering belongs to soil mechanics, which studies the various physical and mechanical properties of frozen soil, the law of freeze-thaw and its changes, the settlement behavior and its mechanism during the thawing process. It provides a theoretical basis and technical ......

Magnetic Abrasive Finishing (maf)
Magnetic abrasive finishing (maf) is a finishing process that utilizes small magnetic abrasive particles suspended in a liquid carrier to apply a controlled material removal to metal parts. maf is a metalworking process that can produce high quality finishes on p......
heat affected zone
Global warming is an increasing concern in the 21st century. Over the past century, average global temperatures have risen by 1.5 degrees Celsius, mainly due to human activities such as burning fossil fuels, deforestation, and industrialization. This increase in temperatures is causing many proble......
monoclinic soda limestone
Dolomite is an anhydrous carbonate mineral composed of calcium magnesium carbonate. It was first discovered in 1792 in northern Italy and was later named after the French mineralogist Déodat de Dolomieu. The most common form of dolomite is a white to tan or greyish color, though other colors such......
granite
Granite is an igneous rock made up of mafic and felsic minerals. It is one of the most popular building materials in the world due to its durability, strength and beauty. Granite is composed mostly of quartz, mica and feldspar, and is commonly found in many types of landscapes.

serpentine asbestos
Serpentinite, also known as serpentine, is a mineral composed primarily of magnesium silicate. It is found in abundance in ultramafic igneous rocks, such as peridotite and dunite, as well as in serpentinites – a type of metamorphic rock formed from the alteration of the ultramafic rocks. Serpenti......
gas hydrate
Natural Gas Hydrates
Natural gas hydrates are a type of solid formed when water molecules are caged around small gas molecules such as climate-friendly methane, carbon dioxide and hydrogen sulfide. Natural gas hydrates are believed to be a possible form of energy storage and production, with an e......

Gneiss
Gneiss is a type of rock formed from the metamorphism of granite or sedimentary rock. It is one of the most common rock types in the continental crust. The name is derived from the German word gneiss which means sparkling.
Gneiss is typically foliated and composed of alternating bands of ......
