thread_title:  Introduction 

message: I live in Yasothon and was bemused when Google turned up scores of references to Rhodic Ferralsols (Yasothon soils) that are wide-spread on the Khorat Plateau and are obviously named after the province. Some time in the past, though I don't recall when or where, I heard that the entire plateau was covered with triple-canopy jungle until about 300 AD, but was clear-cut and turned to laterite during the heyday of the semi-mythical Funan Kingdom. Not being a geologist, I don't know what Rhodic Ferralsols (Yasothon soils) are, or what they might have to do with the clearing of triple-canopy jungles, or the province where I reside, much less with this article. Can anyone help? (They are mentioned on Italian Wiki at Khorat (altopiano) and Suolo ferrallitico, but I don't read Italian, either.) --14:05, 19 December 2010 (UTC)

replies: text: Thanks. Thanks. Yasothon soils used to be classified as laterite until confusion developed over just what that is. And the Yasothon soils were formed in the Triassic, long before the plateau uplifted, or the Funanese moved in. Facts on the ground sure do confuse issues! I'm suffering perturbation (geology) big time. --Pawyilee (talk) 17:30, 20 December 2010 (UTC)

thread_title:  Rhodic Ferralsols (Yasothon soils) 

message: There is another article (http://en.wikipedia.org/wiki/Latosol ) very similar to this one in the german wikipedia there is only one for both, so maybe one should be deleted-- Christian b219 (talk) 22:56, 23 March 2012 (UTC)
thread_title:  Laterite vs Latosol 

message: Zircon is not an oxide, but a silicate of zirconium. This is verifiable by following the link to the zircon article. Therefore I shifted it back so the sentence in question would read in part, "Laterites consist mainly of quartz, zircon, and oxides of ...". Sandhillman (talk) 04:19, 24 March 2013 (UTC)
replies: text: Yes, zircon is a silicate, however the current wording is problematic. "..consist mainly of quartz, zircon..." makes it look like they contain lots of zircon. Don't have access to the ref, but as zircon is a trace mineral in granites I'd be dubious about it being abundant in laterites. Same with the oxides of tin and titanium. Yes, those are perhaps concentrated by the leaching of soluble minerals, but "consist mainly of..." seems to need rephrasing. Vsmith (talk) 15:34, 24 March 2013 (UTC)
thread_title:  Formation Section 

message: This article starts out by referring to laterite as a soil, then refers to it as a rock, then to laterite brickstones, then talks about how it can be cut into stones for masonry and so forth. As a non-geologist, I'm confused, is it a type of soil or a type of rock? I know these sorts of distinctions aren't always clear in the real world, but if this is one of those ill-defined classes then that should be spelled out for those of us in the general audience. To me, if something is resilient enough to cut into slabs that will last thousands of years in architecture, then it's not a soil. If it is just a very compact, non-dispersable soil then that should also be spelled out. Thanks, Mark Marathon (talk) 04:49, 14 June 2014 (UTC)
replies: text: As far as I know laterite is considered a soil, although as it results from deep/intense weathering and re-cementation w/ Al and Fe oxides. As it can be quite compact and "hard" or "rock-like". I've reworded that a bit in the article. Vsmith (talk) 14:48, 14 June 2014 (UTC)
thread_title:  Rock or soil 

message: This is from "Earth: portrait of a planet" (third edition):
Laterite forms in tropical regions where abundant rainfall drenches the land during the rainy season, and the soil dries up during the dry season. Because so much percolating water passes down through the soil, just about all mineral components get leached out of the soil until onlyinsoluble iron and/or aluminum oxide remains. In fact, so much water passes through the soil that accumulation cannot take place, even at depth, and so this soil has no B-horizon.
Yet the picture displays "soil" as A-horizon (the leaching zone), and Laterite forming in the zone of accumulation?  — Preceding unsigned comment added by Dbeecham (talk • contribs) 13:14, 9 August 2015 (UTC)
thread_title:  Soil picture correct? 

message: Hello dear collegues, thanks for a great contribution about laterites knowledgement. In LabMoDA from Porto Velho, Amazon Brasil, we have researching too about local laterites. Here it occurs like a rock mass in hillocks. We are estimulated to improve our studies in laterites, including geothecniques, and to publish it in soon.
