'''Meruda Takkar''' is a [[landform]] located north of Khadir Bet in the [[Great Rann of Kutch]], [[Kutch district]], [[Gujarat]], India. It has a presence of [[alkali feldspar]] [[syenite]] rocks which are of either [[Precambrian]] or [[Deccan Traps|Pre-Deccan]] [[Mesozoic]] [[Intrusive rock|plutonic]] origin. It is described as a hill, an island, an outcrop as well as a [[monadnock]].<ref name=":2">{{Cite journal|last=Thakkar|first=M.

==Geology==
Meruda Takkar is 200 metres long and 90 metres wide in size and has an elevation of 15 metres. These rocks are formed of [[alkali feldspar]] [[syenite]] having [[nepheline]] and [[aegirine]] along with many fine-to-medium grained [[felsic]] dykes. The study proposes two viewpoints of their possible origin. The [[Precambrian]] origin is proposed based on their closeness with Trans Aravalli Belt [[Anorogenic magmatism|anorogenic felsic magmatism]]. The [[Deccan Traps|Pre-Deccan]] [[Mesozoic]] [[Intrusive rock|plutonic]] origin is proposed based to their genesis similar to other rocks such as at Nir Wandh in Pachchham Island, and Mundwara and Sarnu–Dandali complexes in [[Rajasthan]].<ref name=":3" />

Based on the presence of the [[syenite]] at the site; it is assumed that the syenite rocks form the basement for the Kutch Basin sediments.<ref name=":1" /><ref>{{Cite web|date=2015|title=Kutch Basin|url=https://www.ndrdgh.gov.in/NDR/?page_id=742|url-status=live|archive-url=https://web.archive.org/web/20200822074938/https://www.ndrdgh.gov.in/NDR/?page_id=742|archive-date=2020-08-22|website=National Data Repository|publisher=DGH, Ministry of Petroleum and Natural Gas, Government of India}}</ref><ref>{{cite thesis|title=Structural studies on central Kachchh mainland with special reference to quaternary tectonism|last=Sohoni|first=Parag S.|publisher=Department of Geology, Maharaja Sayajirao University of Baroda|url=https://shodhganga.inflibnet.ac.in/bitstream/10603/60120/10/10_chapter%203.pdf|hdl=10603/60120|date=2000-12-31|pages=24-25|access-date=2020-08-22|archive-date=2020-08-29|archive-url=https://web.archive.org/web/20200829121557/https://shodhganga.inflibnet.ac.in/bitstream/10603/60120/10/10_chapter%203.pdf|url-status=live}}</ref> After 180 million years-long erosion, the Meruda Takkar and Nagarparkar hills are the only existing Syenite rocks in the region.

The site was visited in 1968.<ref name=":1" /> Forty-eight years later, a team from the geology department of the [[Kutch University]] visited the site in May 2019.<ref name=":0" />
