Hello fellow Wikipedians,

I have just modified one external link on Duricrust. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:

Laterite

This seems to be the same as Laterite.

• Latterittjord .. Et slikt hardt lag (duricrust) kan motstå erosjonen i en slik grad at det dannes benker rundt dalene.

Quoted from: Verden i dag. 17 : Sentral-Afrika. [København]: Bonniers Bøger. 1995. p. 86. ISBN 8742707277.

• .. , a continous coherent duricrust may develop. The crust is commonly known as laterite but the aluminia-rich variety is identical with bauxite, which in many places is mined as aluminia ore.

Quoted from: Geoecology of the developing world and the role of the earth scientist in the development process. [Trondheim]: Tapir. 1987. p. 83. ISBN 8251908302.

Seems the two articles should be merged.--regards ^ツDyveldi ^{☯ prat} _{✉ post} 15:17, 18 November 2018 (UTC)

Opposed I am opposed to these articles being merged because laterite is only one of serveral very different types of duricrust. For example, calcrete is a calcium-rich duricrust, while laterite is typically devoid of calcium. If a duricrust is silica-rich it is a silcrete. Paul H. (talk) 21:00, 7 September 2019 (UTC)

Are you able to provide some references which discuss this? Rewriting the article with references would be a clarification. Thanks. regards ^ツDyveldi ^{☯ prat} _{✉ post} 06:52, 8 September 2019 (UTC)

Yes, I have the sources to both dicuss this and improve the article. It will take a couple of days to get them together. Paul H. (talk) 23:23, 8 September 2019 (UTC)

One definition might be "A duricrust is a general term for a hard crust on the surface of, or layer in the upper part of, either a soil or weathering zone formed by the accumulation of soluble minerals. They are deposited by mineral-bearing waters that move upward by capillary action and evaporate during a dry season. There are different types of duricrusts, each distinguished by a dominant mineralogy. For example, ferricrete is dominated by sesquioxides of iron; alcrete is dominated by sesquioxides of aluminium; silcrete by silica; and calcrete (caliche) by calcium carbonate." Paul H.

Thanks a lot. The article is much improved. Seems there is much more to say here. I removed the template. regards ^ツDyveldi ^{☯ prat} _{✉ post} 19:40, 11 September 2019 (UTC)

You are welcome. I am planning to do more work on it. Paul H. (talk) 14:30, 12 September 2019 (UTC)
