Wyomingiteis an ultrapotassic, ultramafic igneous rock known as a diopside-leucite phlogopitelamproite, which is characterized by its specific mineral composition including diopside, leucite , and phlogopite, along with lesser amounts of apatite, calcite, magnetite, and sometimes olivine. Wyomingite i...
The rock pictured above was found in a mine and contains raw gold, which is a mineral of chemical formula Au. (Image credit: plastic_buddha via Getty Images) Rocks and minerals hold precious clues about how Earth formed and evolved over billions of years — but what is the difference ...
A mineral is a naturally occurring solid with a structure and definite chemical composition. Although similar to rocks, minerals are the building blocks for making rocks, and are found in various types of rock in differing shapes and chemical compositions throughout the Earth's crust. Although min...
What process creates metamorphic rocks? What are biochemical sedimentary rocks? What are the most common minerals in granite and basalt? What mineral group is feldspar in? How does a sedimentary rock become an igneous rock? What is the parent rock of gneiss?

Procelain clay is a type of raw material that potters and other craftsmen use to create ceramic objects. It is a very smooth clay, typically a white or light gray color, and it is obtained by mining. It contains very few extraneous materials, like sand or minerals. Porcelain clay is ...
Asteroids are space rocks that mostly exist between Mars and Jupiter. They are made of material left over from the birth of the solar system.
silt - A mineral particle ranging in size from 0.002 to 0.02 mm. soil - 1. A material composed of minerals, living organisms, soil organic matter, gas, and water. 2. A body composed of soil and other parts such as rocks, roots, and animals that has size, form, and history and prov...
And that creates distinct layers of soil as far down as the rock underlying the soil. And the materials that dissolve easily in water can get lost completely if the water carries them horizontally out of the soil and into rivers. Now, of course, new mineral and organic material will be de...
