Merge with Lonar crater

The following discussion is closed. Please do not modify it. Subsequent comments should be made in a new section.

It should be the other way. Lonar crater should be merged with Lonar lake as the lake is better known in the country. The lake was used extensively in the past for salt extraction and has historical,legendary,religious, ecological and tourist value. The lake is also being considered for inclusion as Ramsar site under the Ramsar Convention. The lake article has been proposed under the Category of Lakes of India and List of lakes in India. Hence, if at all a merger is to be done then Lonar crater should be merged with Lonar lake.--Nvvchar (talk) 16:51, 2 September 2008 (UTC)[reply]

why dont we merge them both in to Lonar Crater Lake we can put it under that ramsar stuff too right? surely a crater lake goes under lakes of india too. --Zaharous (talk) 15:03, 8 September 2008 (UTC)[reply]

A good arrangement would be to have disambaguation page for Lonar, Lonar crater and Lonar Lake since the three are under different categoaries, viz, Cities and Towns in Maharashtra,Craters, Geography and Geology in Maharashtra and Wiki Project lakes respectively. the lake part is also a bigger component. Further more, the Govt. of Mahrashtra and Govt. of India are funding the conservation works of the lake.--Nvvchar (talk) 15:14, 8 September 2008 (UTC)[reply]

IMO the crater, as the article Lonar crater seems to suggest, appears to be the geological beginning of the formation of the lake. The lake is prominent not as the Lonar Crater Lake, but as Lonar Lake. Hence merging the crater information to this article is more appropriate. Mspraveen (talk) 16:04, 8 September 2008 (UTC)[reply]

Merge into Lonar crater: The crater is more important, as Lonar is known for the crater, the lake is just a by-product of the crater. Maharashtra state tourism advertises it as the "3rd amongst the worlds's five largest craters." [www.maharashtratourism.gov.in/.../MaharashtraTourism/CitiestoVisits/Amravati/LonarAmravati.html], not as a lake. Just google "Lonar", how many times is the crater mentioned first? Always. [1]

"Lonar crater" : 5350 hits [2]
"Lonar lake": 2280 google hits [3]--Redtigerxyz (talk) 05:35, 10 September 2008 (UTC)[reply]

Why look somewhere else, just look closely at the references section of this article: Ref 2 (The Planetary and Space Science Center) discusses the crater, not the lake, ref 3: "Lonar crater saline lake", ref 5: "Lonar, A Gem of Craters", ref 10: "Lonar crater saline lake", ref 11: "Lonar Crater, India", ref 13, 16: lonarcrater.blogspot.com.--Redtigerxyz (talk) 05:46, 10 September 2008 (UTC)[reply]

ref 12 (mtdc) talks about the crater, not the lake. "Lonar Crater was first discovered in 1823 by British officer, J.E. Alexander. It is also written about in ancient scripts like the Skanda Puran, the Padma Puran and the Aaina-i-Akbari." ref 14 starts with "The Lake of Lonar is said to be the only crater " "Buldana Gazzetter".--Redtigerxyz (talk) 12:43, 10 September 2008 (UTC)[reply]

Also, a merge is needed because the crater and the lake are same. The crater is filled with water, thus called a lake.--Redtigerxyz (talk) 12:47, 10 September 2008 (UTC)[reply]

Lonar Lake merged with Lonar crater and moved to Lonar crater lake. --Docku: What's up? 19:46, 23 March 2009 (UTC)[reply]

third largest natural salt lake.

Removed "third largest natural salt lake" as it is Original research, needs a reference if true. The reference provided says third largest crater not salt lake.--Redtigerxyz (talk) 06:17, 10 September 2008 (UTC)[reply]

third largest crater

http://www.unb.ca/passc/ImpactDatabase/asia.html , this link clearly shows that it is not the third largest crater , is it a third under some other subcategory ? also the two other lakes quoted "Bosumtwi lake & new cubec lake(3 ppm )" appear to be fresh water lakes so can they be referred under the same category , as they are right now , clarity would really help jeph (talk) 06:44, 10 September 2008 (UTC).[reply]

new cubec lake

Via google, I found no reference to a "new cubec lake". I did find a reference to a "New Quebec" lake named Lake Jobert http://www.ggl.ulaval.ca/cgi-bin/consultau.cgi?713&647&703&382&12&232&716&117&710&34&656&793&685&478& The original entry on Lonar Lake appears to me to have been entered from memory. I would recommend deleting the references to crater size order. There are about six impact craters 100 kilometers in diameter or greater. Meteor crater list http://www.smv.org/hastings/crater4.html Jim1138 (talk) 08:06, 10 September 2008 (UTC)[reply]

There is a New Quebec Crater. See Pingualuit crater. Jim1138 (talk) 08:17, 10 September 2008 (UTC)[reply]

The article states "New Cubec Lake in Canada with a diameter of 3,500 metres". Pingualuit crater in Canada is 3,440 meters in diameter. Probably the one and the same. Pingualuit crater has extremely low salt content so it is not a salt lake. I am deleting the reference to Pingualuit / New Cubec Lake. It makes no sense. Jim1138 (talk) 08:27, 10 September 2008 (UTC)[reply]

Deleted reference to third largest crater

See above. I also noticed that the "lake mean diameter" was actually the "crater rim diameter". I could not find a lake diameter, so I estimated one by taking multiple measurements using Google Earth. Measurements were from 1.1 to 1.3 km I used 1.2 km as the lake diameter. It probably changes seasonally. Notice the submerged temple. The google earth coordinates are 19.97688n 76.51395e. Hopefully, this is a little more accurate.

Geological Monument of India

In the publication "Geological Monuments of India" by the Geological Survey of India in 2001 Lonar Lake has been listed as Lonar Lake formed by the Lonar crater. Hence, the merger tag has been deleted.--Nvvchar (talk) 07:55, 13 January 2009 (UTC)[reply]

How many impact craters in basaltic rock?

The lead paragraph contains two apparently contradictory statements: Lonar is either "the only hypervelocity meteoritic impact crater on basaltic rock" (second sentence) or it is "the second largest impact crater in basaltic rock" (last sentence). The abstract of the frequently cited 1973 Science article by Fredriksson et al. states that Lonar was "the only known terrestrial impact crater in basalt" at that time. The only more recent article I have found mentioning more than one crater in basalt cites the 1973 Fredriksson et al. article, which seems rather odd. A MaPS article in 1973 by Fredriksson et al. mentions a small (300 m) satellite crater near (~700 m north) the main Lonar crater; could this be a source of possible confusion? For the moment I have added a direct ref to the Fredriksson et al. article and flagged the "second largest" sentence with "citation needed."

According to Pittarello et al. (2010), the recognized extraterrestrial impact craters, which are developed in basaltic target rocks are Logancha (Eastern Siberia), Lonar (India), Vargeao Dome (Brazil), Vista Alegre (Brazil), and possibly Cerro do Jarau (Brazil). In case of Cerro do Jarau, the crater is developed in flood basalts, which have been blown away by the impact to expose within the crater, sandstone underlying the basalts. This paper notes that Vargeao Dome is the largest of the extraterrestrial impact craters developed in basalt. This paper also demonstrates that Lonar is the only formally recognized extraterrestrial impact crater in the Deccan Traps.

Lake ecosystem

The section finishes with the sentence: "Plea to declare Lonar lake a protected wetland." I don't know enough to edit this but I suspect there's a rule against advocacy. Perhaps a reference to a group trying to save the lake environment would fit better. — Preceding unsigned comment added by Vypo9 (talk • contribs) 23:44, 22 June 2011 (UTC)[reply]

Surface Area Wrong

The surface area is given as 1800 meters. That is a linear measurement. It should be an areal one. Maybe a superscript 2 is missing? — Preceding unsigned comment added by 208.181.29.110 (talk) 20:51, 2 March 2012 (UTC)[reply]

The surface area is about 18 ha! Based on own measurements using satellite images... — Preceding unsigned comment added by 217.92.117.245 (talk) 11:51, 30 July 2012 (UTC)[reply]

Flora is partially wrong: in the crater grow only few (< 5) Tamarind trees, which are restricted to the plantation. Babool (Acacia nilotica ) grows with few ecceptions only on the uppermost crater. The lakeshore is surrounded by Prosopis juliflora shrubs, with some neem trees, figs, Annona squamosa, Alangium salviifolium and Phyllanthus reticulatus. (There is one flora available for the crater (Diwakar & Ansari 1995; Journal of Economic and Taxonomic Botany); even they misidentified Prospis juliflora as P. chilensis)217.92.117.245 (talk) 12:10, 30 July 2012 (UTC)[reply]

Magnetic Effects

Very strange magnetic effects within the crater area as reported here: http://10yearitch.com/india-travel-tour/maharastra/lonar-crater-lake/ - stating that a guide "... also placed a couple of compasses on the floor of the temple to show us the strange magnetic field in the area. Both compasses showed opposite directions and when they were moved along the floor of the temple, the needle swung around in circles incessantly" — Preceding unsigned comment added by 86.2.67.237 (talk) 09:05, 9 October 2012 (UTC)[reply]
