The oldest bits on earth

Did you know that Zircon is the oldest known material on earth? I didn’t. Scientists discovered bits of Zircon in Western Australia that are 4.404 billion years old. The Earth formed a scant 150 million years prior to that. Older bits were discovered in a meteorite in Chile, clocked at 4.6 billion years old.

How can this be? From the article:

Zircon contains its own internal atomic clock. Its crystal accumulates atoms of uranium, which decay to lead at a known rate. By measuring the relative abundance of two types of uranium and lead in a zircon, geologists can determine old it is. Zircon is also incredibly durable. It remains unscathed while other rocks and minerals melt and re-form under the tremendous heat and pressure of continental shifts, mountain-building, and violent asteroid impacts.

Yowzah!

In fact, like most of us, I assumed Cubic Zirconia (imitation diamonds) were derived from Zircon. They’re not. The cubic variety is laboratory-grown for your inexpensive pleasure.

Read “Zircon” from the “Add more color to your life” site.

About Michael Coates
I am a pragmatic evangelist. The products, services and solutions I write about fulfill real-world expectations and use cases. I stay up-to-date on real products I use and review, and share my thoughts here. I apply the same lens when designing an architecture, product or when writing papers. I am always looking for ways that technology can create or enhance a business opportunity .. not just technology for technology's sake. My CV says: Seasoned technology executive, leveraging years of experience with enterprise and integration architectural patterns, executed with healthy doses of business acumen and pragmatism. That's me. My web site says: Technology innovations provide a myriad of opportunities for businesses. That said, having the "latest and greatest" for its own sake isn't always a recipe for success. Business successes gained through exploiting innovation relies on analysis of how the new features will enhance your business followed by effective implementation. Goals vary far and wide: streamlining operations, improving customer experience, extending brand, and many more. In all cases, you must identify and collect the metrics you can apply to measure your success. Analysis must be holistic and balanced: business and operational needs must be considered when capitalizing on a new technology asset or opportunity.
