To answer this question, we must first understand how agate and diamonds are formed.
We know that hot lava is bubbling.
IfMagma solidificationtime, theseBubblesBefore it emerges, it will form in solidified magmacavities
If there is nearbySilicic acid solutionAbundantLiquid of silica, under the pressure of volcanoes or geological movements, they fill these cavities.
After the baptism of time or the change of the external environment, these silicic acid solutions willSettle slowlyoutSilica, that is, quartz.
If it is mixed during the precipitation processOther metallic minerals, then different colors and stripes will appear in this quartz crystal, and eventually agate will be formed.
It can be seen that two key conditions are required in the formation of agate:
1. Near volcanic magma.
2. There is silicic acid solution nearby.
Diamonds are the constituent elements areCarbon, the same element as the one in your child's pencil lead.
Carbon inThe pressure is4.5-6.0 gpa(Equivalent to 4 of the atmospheric pressure.)56,000,000 times),TemperatureforThe conditions under which diamonds can be formed, and it takes a long time.
Such harsh conditions can only occur deep underground, near volcanoes, or when meteorites hit the Earth.
The high temperature and pressure environment changes the arrangement of carbon atoms, and eventually it becomes a diamond.
It is not difficult to find that both diamonds and agate are required for the formationVolcanoes, because the volcano is able to provideAdequate pressure and temperature
This is also the reason why a variety of mineral gemstones can be found near the volcano.
If there happens to be a volcano nearby, there probably is.
For example, Madagascar, an island country in Africa, has volcanic rocks all over the island, so they produce water there to wash agate.
However, there are no reports of agate found on the seaside in China, and if you want to pick up agate, you have to rely on the sea water to wash the agate from other places.
But this probability is extremely low, so don't think about getting rich by picking up agateDown-to-earth isThe right way
