Felsic Volcanics Interlayered With Sediments of the Marwar Supergroup at Chhoti Khatu, District Nagaur, Rajasthan

A thick pile of un deformed and unmetamorphosed sediments exposed to the west of the Aravalli mountain range in Rajasthan. earlier known as the Trans-Aravalli Vindhyans and later renamed as the Marwar Supergroup, are considered to rest unconformably over the Malani Igneous Suite of rocks. Felsic volcanics have been observed around Chhoti Khatu. in Nagaur district for the first time interlayered with sediments of the Marwar Supergroup. They occur sandwiched between the underlying Sonia Formation and the overlying Girbhakar Formation of the Jodhpur Group (the Marwar Supergroup). This interesting relationship may help in deciding the age of the Marwar Supergroup.
