Chaudhri, AR, 2015, Preliminary report on the exposure of fluvial sediments near Mugalwali village in Bilaspur Subdivision, Yamuna Nagar Dist., Haryana (19 May 2015) Embedded.
Water appeared at a depth of 2m to 3m.in the bed of a paleo-channel aligned to the Sarasvati River as shown in the revenue record of Yamuna Nagar.
The field studies reveal that the sediments in the channel are of fluvial nature and were accumulated in the river channel in the geologic past. Such features as current/cross bedding, fine to coarse laminations, medium to coarse sand and granule sized rounded to sub rounded fragments of white quartzites, chert limestones, sandstones and siltstones and overall medium to coarse grained nature of the sediments confirm that the sediments have not traveld far from the piedmont reach. The nature of cross bedding suggests torrential highly agitated turbulent nature of water in a shallow fluvial depositional environment. At other places where the waters were comparatively less agitated, the direction of flow of current was broadly from North to South indicating that the source of the river carrying these sediments must have been in the Himalayas. This is supported by the orientation of the mega-clast also. In a number of cross sections, that the author examined, the two banks of the excavated channel are clearly discernible having coarse granule to coarse sand sized particles (channel sediments) in the lower part, and fine to very fine sand, silt and clay sized particles, at places, showing finely laminated nature in the upper part as levee deposits...
Heavy mineral assemblages comprises zircon, tourmaline, rutile, epidote, chlorite/chloritoid, garnet staurolite, kyanite, and sillimanite besides opaque minerals. The overall mineral assemblage is suggestive of a higher Himalayan source comprising metamorphic rocks. Angular to highly angular nature of the grains and almost euhedral nature of tourmaline is suggestive of first cycle origin of a part of the sediments...
To sum up, the investigations carried out so far reveal the following:
The excavated portion is the paleo-channel of a river.
The paleo-channel more or less coincides with the path that the erstwhile Sarasvati River followed, as shown in the revenue records.
The paleo-channel has typical fluvial characters.
The sediments were derived from the higher Himalaya as is indicated by the dense mineral suite.
The sedimentary structures preserved in the sediments suggest that these were deposited in highly agitated, turbulent waters.
The OSL dating as and when completed shall throw light on the age of deposition of the sediments.
The nature and type of water in the channel is likely to be investigated by the Central Ground Water Board.
