Summary
Description Jack Hills, Western Australia (Landsat 5 TM, 2009-07-14, detail).jpg |
English:
Contrast-enhanced true color satellite image (Landsat 5) of the Jack Hills in Western Australia. The rocks of the Jack Hills are very old (~ 3 Billion years) and belong to the so-called Yilgarn Craton. Yet some of these rocks, the Jack Hills conglomerate (actually a metaconglomerate) contain individual grains of zircon which are even older, more than 4 Billion years old. They are used by geoscientists to reconstruct the very early history of the earth.
