Radiometric dating of moon rocks
Try it risk-free What can the sun do that we can't? Are radioactive isotopes helpful in the medical field?The answers to these questions can be found in this lesson on the applications of nuclear chemistry.However, it was soon pointed out by a geologist that minerals dissolved from ancient strata can harden around a recent object, making it look impressive to someone unfamiliar with geological processes.In fact, the style of the hammer would lead us to recognise it as nineteenth-century in date and of definitely American provenance.In June 1936, Max Edmond Hahn (1897-1989) and his wife Emma Zadie Hahn (née Pearl) (1899-1995) were walking along Red Creek, near their home in London (Texas, USA), when they spotted a rock nodule with a piece of wood sticking out from it.It was sitting on a ledge by a waterfall on the river, not attached to any of the solid rocks around it.There are several areas where small waterfalls exist on Red Creek, the closest being about 10 km south-west of London.According to some versions of the story, the discovery took place in 1934; sometimes, Max is called Frank, for reasons unknown.

Instead, he continues to use it as evidence for high technology in the distant past and the relatively recent formation of much of the geological column (during the mythical flood of Noah).
One of his principal selling points is the allegedly impossible composition of the iron in the hammerhead.
Remember, it was found on a ledge near a waterfall. The nodule is not a detached part of the bedrock, but a concretion made from once dissolved carbonate minerals that precipitated out as the water evaporated.
In other words, the nodule could easily be of nineteenth-century date.
