Abstract

The Dharwar system of rocks in Karnataka comprises of shales which are basically sedimentary rocks having high content of clay and silt. They generally exhibit laminated structure and possess low strength, low permeability and high water sensitivity. Apart from several uses, the shales are considered to be prominent source of oil and natural gas including their use as seals in the petroleum traps and reservoirs. In the present paper, it is attempted to present the properties and uses of shales of the Dharwar system which is 4-1 billion years old and has special distinction of being the first and oldest metamorphosised sedimentary rock system in India. Due to its unpredictable behaviour, shales are found to be difficult rocks to classify, sample and obtain reliable test results for their use in engineering works. The origin, distribution, classification, properties and the possible uses of shales of Dharwar system are briefly discussed and their engineering evaluation for construction also has been presented.
