The general Geology and Sedimentology of the Horton sedimentary deposits of Rawdon Hills were studied by using two drill cores and a few outcrops available in the area.

Vitrinite reflectance and fission track method were employed to detect the paleo-tectonic activities of this region. In the case of fission track dating apatite grains were separated, mounted and irradiated. Finally the induced and spontaneous tracks were counted to get an average age of 170 m.y. which locates the samples in the paleo-partial annealing zone.

Vitrinite reflectance rank values revealed the possible maximum depth of burial to be around 4000 metres at the time of coalification. The minimum required temperature for coalification was 90 to 98^oC for a period of 170 m.y.

Finally, the relation between the ages recovered by fission track technique and the Atlantic ocean rifting during Jurassic and cretaceous was discussed.
