•Serpentinization accompanied by:
-Redox and H2 generation
-Volumetric change
•3.3 g/cm3
•2.7 g/cm3
-Heat generation
Syenite - Wikipedia, the free encyclopediaSyenite is a coarse-grained intrusive igneous rockof the same general composition as granite but with the quartz either absent or present in relatively small amounts (
Talc is a mineral and is not classified as metamorphic, sedimentary, or igneous as are rocks.
A rock that deforms like molded clay is called a plastic rock. These rocks can be easily reshaped due to the internal flow of their minerals. Examples of plastic rocks include shale, claystone, and serpentinite.
Talc is formed from the metamorphism of magnesium-rich rocks, such as serpentinite. It is classified as a metamorphic rock, which means it is formed under intense heat and pressure deep within the Earth's crust. Therefore, talc is considered an intrusive rock.
Soapstone forms through regional metamorphism, which occurs over large areas and at high pressures and temperatures. It is mainly composed of talc, which forms from the metamorphism of magnesium-rich rocks like peridotite or serpentinite.
none is really sure
serpentinite
Serpentinite can contain the mineral Chrysotile, also known as white asbestos. Asbestos is carcinogenic (cancer causing) and can also if inhaled cause serious lung problems and is best avoided!
There are no known kimberlite or lamproite volcanic pipes in California. There are many serpentinite bodies present, but these are generally not volcanic pipes and are not of deep seated origin.
Serpentinite is a rock composed of serpentine minerals.I am going to drive a serpentine road tomorrow.

The protolith of soapstone is usually ultramafic rocks such as serpentinite or peridotite. These rocks undergo metamorphism due to high heat and pressure, resulting in the formation of soapstone.
