Where is silver found in nature?
Silver is generally found in rocks, and as a constituent of minerals like acanthite. It can also be found near the surface, in soils and sands, in nearly pure masses, or nuggets, from tiny to hundreds of kilograms, which have been torn from their host rock and smoothed and rounded by glaciation or rivers.
Glam rock was influenced by many things. Most of all, 1950s rock 'n' roll. The production values were influenced heavily by late Beatles albums. In essence, Glam combined the driving guitar work of rock with the string arrangements and musical texture of George Martin's arrangements.
What is the Virginia state rock?
Virginia has no official rock or gemstone. You might consider listing the official fossil which is Chesapecten jeffersonius which was given official status in 1993 by the legislature.
What are the Minerals of West Virginia?
The Coal of West Virginia can be found in 53 of the 55 counties.
What are Arkansas' top three minerals?
The diamond is the hardest mineral and is the state mineral of Arkansas.
What is Pennsylvania's state stone or rock?
The state rock of Pennsylvania is the trilobite.
Actually, the trilobite is the state FOSSIL of Pennsylvania. PA does not have a state rock or a state mineral yet, though suggestions have been made.
What is the hardness of a ruby on the Moh's hardness scale?
A ruby is a mineral corundum. The Mohs hardness scale lists the following from softer to harder:
Talc - 1
Gypsum - 2
Calcite - 3
Fluorite - 4
Apatite - 5
Feldspar - 6
Quartz - 7
Topaz - 8
Corundum (which includes the ruby) - 9
Diamond - 10
Ruby has a Mohs hardness of 9.
What does silver look like in rocks?
Black to dark Grey, in most cause, though very rare to fine silver seams !
How does the rock cycle look like?
For a diagram, see the link below under the tab, 'Related Links'.
== ==
The rock cycle is the natural process in which rocks transform from one rock type into another rock type over time, a type of natural recycling.
Igneous rocks, which are formed from magma cooling underground, or lava above ground are formed from previous igneous, metamorphic, or sedimentary rocks which have become melted, usually as a result of plate collision and subduction.------->
When these igneous rocks are exposed to weathering and erosion, they break down into smaller particles that are transported by wind and water to a place of deposition, where they can form into sedimentary rock strata, through a process of lithification, where excess water is squeezed out by overburden pressures and the particles are cemented together by various minerals precipitating out of solution. Igneous and metamorphic rocks can both be turned into sedimentary rocks in this way.------->
Igneous and sedimentary rocks can also be changed by heat and/or pressure into metamorphic rocks, by transforming their existing mineral structures into new minerals or realigning the existing minerals. There are different degrees of metamorphism, so even an existing metamorphic rock can become a different metamorphic rock. -------->
If these metamorphic rocks are melted, then solidify, they become igneous rocks, and the cycle starts all over again.
The rock cycle is largely driven by lithospheric plate movements which cause subduction and uplift, also by climatic conditions and the associated erosional elements.

Silica is typically mined through open-pit mining or quarrying. The silica-rich material is then extracted and processed to separate the silica compound from other minerals. This process can involve crushing, washing, and refining the silica to achieve the desired purity levels for various industrial applications.
Name of the famous rock in New Hampshire?
The famous rock in New Hampshire is called "The Old Man of the Mountain." It was a series of granite cliff ledges on Cannon Mountain that appeared like the profile of a man's face. However, the formation collapsed in 2003.
What group of rocks is marble in?
Marble is in the carbonate mineral group. Limestone and dolomite are also in the carbonate mineral group. Marble is formed from limestone.
use a filter, its easy. poor it into the filter and the water will drip through. BOOM! easy as that
What do you call a stone polisher?
A person who polishes stones is typically referred to as a lapidary or a stone polisher. If you want check lapidary's work you can visit Cabochonsforsale to know all the things.
How can the streak test be used to identify the two iron minerals limonite and hematite?
Hematite has a red streak. It can vary in depth of color, depending on the variety of hematite.
Limonite has a yellow-brown (More brown than yellow) streak. But you have to make sure you are streaking the limonite and not an underlying mineral, if the limonite is located on another mineral.
I am almost positive that it is Igneous, sedimentary, and metamorphic
