WebIn geology, rock (or stone) is any naturally occurring solid mass or aggregate of minerals or mineraloid matter. It is categorized by the minerals included, its chemical composition, and the way in which it is formed.Rocks form the Earth's outer solid layer, the crust, and most of its interior, except for the liquid outer core and pockets of magma in the asthenosphere.

WebLunar soil is the fine fraction of the regolith found on the surface of the Moon.Its properties can differ significantly from those of terrestrial soil.The physical properties of lunar soil are primarily the result of mechanical disintegration of basaltic and anorthositic rock, caused by continual meteoric impacts and bombardment by solar and interstellar charged atomic …

WebThe naming of a lithology is based on the rock type.The three major rock types are sedimentary, igneous, and metamorphic.Igneous rocks are formed directly from magma, which is a mixture of molten rock, dissolved gases, and solid crystals.Sedimentary rock is formed from mineral or organic particles that collect at the Earth's surface and become …

WebA geologist is a scientist who studies the solid, liquid, and gaseous matter that constitutes Earth and other terrestrial planets, as well as the processes that shape them.Geologists usually study geology, earth science, or geophysics, although backgrounds in physics, chemistry, biology, and other sciences are also useful. Field research (field work) is an …

WebBiotite is a common group of phyllosilicate minerals within the mica group, with the approximate chemical formula K(Mg,Fe) 3 AlSi 3 O 10 (F,OH) 2.It is primarily a solid-solution series between the iron-endmember annite, and the magnesium-endmember phlogopite; more aluminous end-members include siderophyllite and eastonite.Biotite was regarded …
