General Description:

Malani Volcanic Province: The Neoproterozoic Malani bimodal volcanics constitute the largest suite of anorogenic acid volcanics in India that has aerial spread of over 3100 km2 in the state of Rajasthan. The 745 ± 10 Ma old volcanism succeeded the granitic activity of Abu Pluton and ceased before the onset of Marwar sedimentation. Volcanism initiated as basaltic eruption with occasional andesite or trachybasalts followed by voluminous outpouring of peralkaline and peraluminous rhyolite, basalt, dacite and trachyte flows and terminated with the outburst of ash flow deposits.  The other rock types associated with rhyolites are trachytes, dacites, pithstones, welded tuff, vatic, lithic and crystal ash, ignimbrite, obsidian, pyroclastic slates, agglomerate, volcanic breccia and volcanic conglomerates. Majority of the acid volcanics are high potassic and few are calc-alkaline or low potassic in composition. Essentially eruptions were under terrestrial conditions through fissures, shield volcanoes and central cones. The “hot spot” triggered volcanism in an extensional tectonic regime of continental crust had initial basaltic magma generated at greater depth. This magma while migrating upwards supplied additional heat for the partial melting of lower sialic crust resulting in the generation of felsic magma. The crustal extension has helped in the upward advancement of the felsic magma. The crustal extension has helped in the upward advancement of the felsic magma.

Thar Desert: A large part of the journey in this field trip is through western Rajasthan that constitutes the Thar Desert. The desert with its boundaries towards north, east and south by Ghaggar-Sutlaj rivers, Aravalli hill ranges and Great Rann of Kachch respectively has an average elevation of 200-300 m MSL. The Quaternary continental sediments in the Thar Desert comprise a multiple episodic succession of fluvial, fluivo-lacustrine and Aeolian deposits. Saline depressions, ranns or playas within the desert represents evidences of receding sea. A variety of sand dunes like parabolic, transverse, reticulate, longitudinal, barachans etc are common. Interdunal plains host gypsite/calcrete beds. The Thar, like any other desert, conjures up a vision of a vast emptiness where man ekes out a miserable existence, harassed by a pitiless wind that batters him with a million sand grains. Yet history shows that the deserts have been both the refuge and cradle of civilizations. The participants are exposed to glimpses of history of Thar, the valour of warriors, splendours of kings and the architectural marvels of medieval India. The journey, it is hoped, would be extremely pleasant and memorable.

Some Useful Comments: Some other points pertinent to this field are:

  • The month of February is one of the best periods to visit this part of India. The weather is comfortable. The maximum temperature varies between 30 degree Celsius during the day and 10 degree Celsius during the night.  Light woolen cloths are required during the evening times.

  • Accommodations at all the places will be shared rooms in good tourists’ hotels. Cuisine in most places is likely to be Indian, which could mildly spicy. The hotels would provide multi-cuisine food, including continental. Safe bottled water is recommended for drinking and would be arranged.

  • Malaria and other mosquito borne diseases are rare in this region in the month of February, however, it would be advisable to consult your respective nation consulates or WHO sites on any health warnings.
  • Field Trip Guide books will be posted in the website and printed copies with maps would be made available to all the participants.

  • There would be adequate opportunity for collection of field samples at all locations. The field party leaders would guide the participants about the sample collection. Participants who wish to collect samples are (i) invited to bring their preferred sampling equipments (ii) sample packing material and (iii) should be prepared to cover the cost of sample shipment.
  • All road travels from Jodhupur to Jaipur are by 35-seat air-conditioned luxury coach. Road travels from the main road to the kimberlite locations are by field vehicles.

  • There is no specific dress code for the field trip. But in view of local weather conditions light trousers and light shirts are recommended.

  • Participants must arrange for their own travel and medical insurance.
