What Micrometeorites Tell Us
About Our Solar System.
Through studying these spinel grains from
various time periods of their chemical and isotopic structure, we can evaluate the
differences in the movement of different forms of meteorites that impacted Earth over the
times. We can also obtain knowledge about ancient occurrences in our solar system, such as
the break-up of 100-km-sized objects that contributed to the formation of asteroid groups of
1000s of bodies in the asteroid belt.
Significant disruptions of the asteroid
belt, as seen in the meteorite flux, can also suggest tiny disturbances of the orbits of the
planets, likely linked to large-scale astronomical disturbances of the solar system. This
gives us clues about the constellation of the asteroid belt and the events that happened in
the solar system long time ago, and how this impacted our Earth.

THE QUESTION
Why Such Stones?
Almost all meteorite forms contain a trace
of spinel minerals, which withstand weathering and can be recovered by acid-dissolution of
large samples (100–1000 kg) of progressively formed sediments of any age. Spinel grains are
extracted from micrometeorites, meteorites, or asteroids and also provide important data on
the varieties of extraterrestrial matter that fell on Earth at distinct periods in the
geological past.
In summary, the spinel statement given here will enable us to
consistently, in great detail, and on a strictly scientific backing, correlate major
astronomical events to the sequence of microbial, geologic, and climatic occurrences on
Earth. A pioneer astro chronology for Earth's geological record can be established,
supplementing existing bio-, chemo-, and magnetostratigraphies.

With over ten years of marketing
experience, I finally decided to settle down in Bangkok to work in an area that I have
always been interested in: the gemstones industry. I'm still learning how the market works
on a daily basis, and I enjoy sharing my experience with those who are interested in
learning more about gems in general.
