How was mineral discovered?
When liquid magma cools it crystallizes to form an igneous rock composed of a variety of different minerals. Once a mineral deposit has been found it has to be extracted from the ground to access the valuable minerals it contains. This can be done by opencast quarrying or underground mining.

Because NYC bedrock has been so thoroughly exposed, a surprising number of minerals have been found here. The current list of the minerals from New York City include 129 valid mineral species.
Does New York have any minerals?

What types of rocks and minerals do you think can be found in New York City?
This contains rocks from the New York City group (gneiss, schist, marble, and pegmatite) and the associated minerals. Almandine garnet, orthoclase, schorl, muscovite and apatite have been found in recent years.
What was the first mineral on Earth?
diamond
We concluded that the first mineral was diamond—pure carbon condensed from the expanding atmospheres of energetic stars. Approximately a dozen “ur-minerals,” including nitrides, carbides, oxides, and silicates, condensed as micro-crystals at temperatures greater than 1500°C.
What is the newest mineral on Earth?
An “amazing” new type of mineral has been discovered by scientists analysing a rock mined in Cornwall about 220 years ago. The dark green mineral has been named kernowite after Kernow, the Cornish language word for Cornwall.
What gems can be found in New York?
A wide variety of rocks, minerals, and gemstones can be found in New York including garnet, fluorite, labradorite, hematite, quartz crystals, sphalerite, sunstone, barite, and pyrite. The world-famous Herkimer Diamonds can also be found in central New York.
Is NYC on bedrock?
450 million years ago, New York City was situated where the continental plates collided and was trapped roughly in the center of the newly formed super-continent, Pangaea. Today, all that remains of these mountains are their stumps which are the bedrock of modern-day NYC.
Why is there no gold in New York?
New York is certainly not the place to prospect if you would like to get rich. There is gold in New York, but according to state law, all gold and silver found in the state is the property of the state. Any gold in the state will be glacial gold left by the receding glaciers that traveled down from Canada.
What type of rock is the most abundant in NY?
View of a granite quarry in New York State. Granite is considered the most abundant rock in the continental crust, whereas the much denser basalt is the main component of oceanic crust.
How old is the oldest mineral on Earth?
4.375 billion years old
By zapping single atoms of lead in a tiny zircon crystal from Australia, researchers have confirmed the crystal is the oldest rock fragment ever found on Earth — 4.375 billion years old, plus or minus 6 million years.
What is the oldest crystal on Earth?
zircon crystals
The oldest pieces of rock on Earth, zircon crystals, may have formed in craters left by asteroid impacts early in the planet’s life. Zircon crystals are more than 4 billion years old.
Where are the mineral collections in New York?
World-Famous Mineral Collections. The New York State Museum houses specimens from several notable sites throughout the state, including 93 mineral species from the Balmat-Edwards mining district in St. Lawrence, super garnets from the Barton Mine in the Adirondack Mountains, and Herkimer diamonds from Herkimer County, New York.

How are the chemical elements of minerals discovered?
The chemical elements were discovered in identified minerals and with the help of the identified elements the mineral crystal structure could be described.
