- #SilicateMinerals are rock-forming minerals made up of #silicate groups. They are the largest and most important class of minerals and make up approximately 90 percent of Earth's crust.
In mineralogy, silica (silicon dioxide) SiO2 is usually considered a silicate mineral. Silica is found in nature as the mineral quartz, and its polymorphs.
On Earth, a wide variety of silicate minerals occur in an even wider range of combinations as a result of the processes that have been forming and re-working the crust for billions of years. These processes include partial melting, crystallization, fractionation, metamorphism, weathering, and diagenesis.
Diatomaceous earth, a biogenic form of silica as viewed under a microscope. The imaged region measures approximately 1.13 by 0.69 mm.
Living organisms also contribute to this geologic cycle. For example, a type of plankton known as diatoms construct their exoskeletons ("frustules") from silica extracted from seawater. The frustules of dead diatoms are a major constituent of deep ocean sediment, and of diatomaceous earth
Best explanation so far. Subscribed.
Yes you did!
only halfway through and im so so so so so grateful for this video. It explains the topic so easily and precisely. thank you
This is awesome! Very cool video!
You are great
this explains soo much, thx
very well explained, thank you
Excellent contents and clarity of the presentation for anybody to learn minerology. It could have been nicer if the quality of the images is improved.
I love it so much! thankyou!!!!
Great video but the sound of the writing device is annoying as heck.
