SummaryThe alkali syenites of the Mundwara magmatic suite, Sirohi district, Rajasthan, in north-western India, are chiefly developed in the Musala hill of the complex. They comprise three principal varieties representing different stages of crystallization, viz. nepheline-sodalite syenite, nepheline-barkevikite microsyenite, and nepheline poor leucosyenite. The dominant constituent of these hypersolvus syenites is alkali feldspar, an orthoclase microperthite showing a variable degree of exsolution. The chief mafic mineral is a distinctly green and zoned sodic pyroxene, close to aegirine-augite in composition. A brown calciferous amphibole, identified as a barkevikite, is developed in addition in the microsyenites. Reddish brown biotite of the phlogopite-annite series is common to all the syenites. The petrography and mineralogy of the syenites are discussed, and a comparative study of the Mundwara syenites with similar rocks of the Deccan volcanic province is presented. Chemistry and mineralogy of the syenites of the Mundwara suite suggest that they are related to those associated with the Deccan volcanic province.

It is widely recognized that interpretations about the planet Mars must begin by using Earth as a reference, because Earth analogues can provide ground truth to constrain interpretations on the geological history of Mars. Fortunately, Deccan Basalt and its derivatives, exposed in Kutch area of Gujarat, can be considered as best candidate from Indian subcontinent to approximate this analogue in terms of petrology, stratigraphy and geochemical similarity. It is believed that Deccan Volcanic province with its extensive volcanic plains, cones and craters as well as abundant hydrous sulphates of secondary origin, approximates the geological, geomorphological and environmental conditions on the Mars.
