Présentation
The study area predominantly encompasses the Marwar, Banner and Jaisalmer basins, covering the semi -arid, arid and hyper arid terrains of the Thar desert. The study area is bounded between the north latitudes 25° 30-28° 00* and east longitudes 70° 30‘- 73°30‘.

The present endeavour aims : 1. To study the genesis and development of calcretes and ferricretes and their utility in understanding the palaeoclimatic changes. 2. To appraise the geotechnical feasibility of these duricrusts in the road construction as pavement aggregate.

The study aims at the following objectives : (i) To map the distribution of calcretes and ferricretes in space through ideally exposed sections. (ii) To bringout the chemistry, mineralogy, micromorphology of calcretes and ferricretes. (iii) To illustrate the significance of calcretes and ferricretes in deciphering micro environmental changes leading to palaeoclimatic inferences. (iv) To evolve models for the genesis and development of these duricrusts. (v) Evaluation of the geotechnical characteristics of calcretes and ferricretes and their utility as road paving aggregates

Mots clés : Calcretic Duricrusts Ferricretic Geotechnical Palaeoclimatic
