A team of archaeological scientists in the United States and Germany say they have developed a technique to accurately determine the age of stone tools and artifacts between 50,000 and 100,000 years old, a period that has proved particularly tricky to map with other methods.

Looks like they're measuring a layer of sio2?

Hmmm, I would have expected some disciple of the Institute for Creation Idiocy to turn up with an "all dating is bogus" rant by now.

What good is this technique? We already know that everything is 6,000 years old.

They are doing measurements withing a layer of SiO2, however they are measuring H2O contained therein. The water bonds to the SiO2; less strongly than a covalent bond but stronger than an hydrogen bond. Apparently, the H2O diffuses inward in a temperature dependent manner.
Types of clay can be dated by heating and measuring the water loss.

Interesting, but I see a problem here:
In comparison, the most popular technique for determining the age of archaeological finds, radiocarbon dating, is only effective for objects that are less than 50,000 years old. It is also limited to organic matter, and therefore can't be used on stone tools or statues. Another technique, potassium-argon dating, works on minerals, but tends to be accurate only when artifacts are between 100,000 and 4.3 billion years old.
[SNIP]
The group verified their theory by measuring the hydration levels on various artifacts with known ages, including Olmec pendants from Mexico and belt buckles from Austria. They also conducted tests on 100,000-year-old objects found on Lukenya Hill in Africa.
Since the half-life of potassium-40 is about 1.25 billion years, which creates a statistically-huge margin of error at 100,000 years ("Potassium-argon dates usually have comparatively large plus or minus factors--they may be on the order of 1/4 million years for a 2 million year old date.": Chronometric Techniques–Part II: Potassium-Argon Dating), this verification sounds necessarily imprecise to me. I'll look forward to seeing the peer review of the article and how this is addressed.
