Cave dating

As water runs through the ground, it picks up minerals, the most common of which is calcium carbonate.

A homogeneous, fine yellow soil covered more than one million square miles of Europe, Asia, and North America.

But the first radiocarbon dates showed that Chauvet Cave had been occupied twice starting about 35,000 years ago.

The Aurignacian people, among the first to live in Europe, brought to the cave a fully formed artistic tradition that used a variety of techniques involving charcoal and a type of red pigment.

Here, we present 24 new radiocarbon accelerator mass spectrometry (AMS) and 6 uranium-thorium (U-Th) analyses from the calcite of the gours, 4 AMS 14C dates from charcoals trapped in the calcite, and 4 AMS 14C analyses on organic matter extracted from the calcite.When the mineral-rich water drips into caves, it leaves behind solid mineral deposits—the same solid material that forms white spots on water faucets or glass dishes.The mineral deposits accumulate in the well-known icicle-shaped rock on the ceiling, a stalactite, and in a mound on the floor where the drip lands, a stalagmite.(Photograph copyright Paul Williams, New Zealand National Institute of Water & Atmospheric Research)Scientists are trying to glean more climate information from speleothems.Less well known, water deposits can also dry in a flat slab called a flowstone. 100% Free Online Dating for Cave City Singles at Mingle2
