File talk:Jack Hills, Western Australia (Landsat 5 TM, 2009-07-14, detail).jpg

Inaccuracy

The originally uploaded image from earthobservatory.nasa.gov does actually not show the entire Jack Hills but only a quite small portion of it. According to maps in several geological publications (e.g. doi:10.1016/j.precamres.2004.09.001: [1]; doi:10.1016/j.gr.2017.11.008: [2]; doi:10.1080/08120099.2013.806359 [alt.: RG]) the Jack Hills comprise the whole S-shaped range which extends from about 26°15′S 116°50′E to about 25°55′S 117°21′E. The feature shown in the originally uploaded image is basically only the ridge called Eranondoo Hill at about 26°10′S 117°00′E. It is an important sampling location for the Jack Hills conglomerate that contains the zircons of which some have been dated as earliest Precambrian (Hadean). This is probably why this ridge is erroneously shown as the entire “Jack Hills” at earthobservatory.nasa.gov. Because the originally uploaded image is not only factually wrong (including false labelling) but also very small and of low resolution and used in quite a lot of Wikimedia projects, I am going to overwrite it with a satellite image that shows the whole Jack Hills. This image has approximately the same ground resolution as the originally uploaded image (which is a Landsat image as is the one that I am going to use as replacement), i.e. the image will not show more detail but only a larger area. --Gretarsson (talk) 19:21, 28 August 2019 (UTC); last modified 21:08, 28 August 2019 (UTC)
