Talk:Alluvial deposit

Its one and the same thing.Rolinator 09:53, 29 October 2006 (UTC)


 * A placer deposit and an alluvial deposit are not the same - the former are economically valuable, and as described in the article are heavy minerals such as gold or gemstones; the latter are much broader in scope and are any materials (usually NOT particularly economic) deposited by alluvial processes, thus including mud, silt, sand, gravel, etc. If "placer" and "alluvial" were the same, you could use the words interchangably, but you can't. So, I disagree with this merge idea. --Geologyguy 15:05, 29 October 2006 (UTC)


 * Your point about "alluvial depsosits" being more than purely restricted to economic objects is valid, but it could also be simply termed 'alluvium', or 'alluvial sediment'. Why do we need the word 'deposit' in there? And as far as the text f the current article goes, there is no particular distinction, shall I quote it with the parts in bold which refer explicitly to the economic interest in 'alluvial deposits';

An alluvial deposit is an accumulation of alluvium (sediment), sometimes containing valuable ore and gemstones, or simply consisting of gravel, sand, or clay, in the bed or former bed of a river. '''Valuable materials such as gold may be extracted using techniques of placer mining. Historically, gemstones (diamonds in particular), were found in the gravels of India. They continue to be mined from alluvium in Myanmar and Sri Lanka.''' Glacial deposits known as till are not alluvium, as they are deposited directly by glaciers, but till is often reworked by streams to produce alluvial deposits.


 * See? My quesions still stands; if the article talks in the majority about placer deposits, merge. If not, we should call it alluvium, because saying alluvial deposit is frankly a tautologyanyway; you can't get alluvium without some alluvium being deposited. In my opinion there's no point having tautologies as articles. Rolinator 23:18, 29 October 2006 (UTC)


 * Actually, given that there is an article on alluvium, indeed this article alluvial deposit is redundant. Sorry that I failed to check that earlier. So, as far as I'm concerned, the info in this "alluvial deposit" article can be merged into either "placer deposit" or "alluvium" or both, and this article deleted or redirected.

Made redirect to Alluvium - not much to merge to either alluvium or placer. Simply a redundant article. Vsmith 01:53, 30 October 2006 (UTC)
