This technique is generally used to date igneous and metamorphic rock, which are rocks that were once melted due to extreme heat and pressure.

Radiometric dating determines how long ago the liquid rock solidified into solid rock.

The man's body was recovered and pieces of tissue were studied for their C content by accelerator mass spectroscopy.

The best estimate from this dating technique says the man lived between 33 BC. From the ratio, the time since the formation of the rock can be calculated.

C and counting the amount of each) allows one to date the death of the once-living things.

Perhaps you have heard of Ice Man, a man living in the Alps who died and was entombed in glacial ice until recently when the ice moved and melted.

While the oldest known rocks on Earth are about 3.5 billion years old, researchers have found zircon crystals that are 4.3 billion years old [source: USGS].

ANSWER: Sedimentary rocks cannot be dated directly using radiometric dating, which is based on the idea that when rocks are in liquid form, their radiometric clock resets.Sedimentary rock on the other hand consists of sedimentary particles which were removed and deposited somewhere else by some sort of fluid (generally wind and water).The sedimentary particles predate the rock which they form.Dating the particles which make up the rock wouldn’t give you the age of the rock itself.In addition, the redeposition process upsets the conditions necessary to achieve accurate results through radiometric dating.

The boat of a pharaoh was discovered in a sealed crypt and reassembled in a museum near the pyramids (see Fig. The age of our galaxy and earth also can be estimated using radioactive dating.
