There is a hammer artifact that was found in the sedimentary material of the uplift in the 1930s.[1] To this day it is a source of controversy as the hammer itself can't be duplicated with current metallurgy technology. — Preceding unsigned comment added by Eyreland (talk • contribs) 02:30, 20 August 2012

Sorry, but a description of an old hoax (or whatever) in a fringe book is not a WP:RS Vsmith (talk) 02:44, 20 August 2012 (UTC)Reply

What (talk refers to is a creationist hoax involving a historic artifact, called the London Hammer and coated by modern travertine. Paul H. (talk) 01:43, 1 January 2020 (UTC)Reply

Significant numerical error in listed size of area

Latest comment: 1 month ago6 comments2 people in discussion

In the fifth paragraph of this article, with heading "Precambrian rocks" there is a significant numerical error in the specified size.

The sentence begins "These rocks consist of about 900,000 km² (350,000 sq mi) of Middle Proterozoic crystalline basement...". The relatively small area in question is in central Texas. Since "350,000 sq mi" is significantly more area than the entire state of Texas (about 270000 sqmi), the size specified is clearly mis-stated and must be corrected. The area would appear to be nearer to 3500 sqmi (~9000 sqkm), but I do not know the actual correct area and thus do not know how to correct the article.

Yes, it is a big mistake. Someone will have to find an estimated size from a reliable source. Your estimate is certainly close as a Texas Parks and Wildlfie website, "Hill Country", states "Size: Edwards Plateau: 31,000 sq mi, Llano Uplift: 5,000 sq mi". However, there must be a better and more definitive source out there somewhere. Paul H. (talk) 02:36, 24 July 2025 (UTC)Reply

Additional note: I found figure of "...~9000 km2 of Middle Proterozoic crystalline basement..." on page 7 of Mosher et al. (2008) Paul H. (talk) 03:08, 24 July 2025 (UTC)Reply

Excellent find. Mosher is an acknowledged expert on Central Texas geology. I'll take his 9000km2 (~3500mi2) as an excellent correction. You make the edit to the document or should I? Wikipotts (talk) 03:44, 24 July 2025 (UTC)Reply

Sorry. Forgot to sign previous reply. Wikipotts (talk) 03:45, 24 July 2025 (UTC)Reply

The corrrection has been made. By the way thanks for the heads up on this error. It is well appreciated. Paul H. (talk) 17:40, 24 July 2025 (UTC)Reply
