Macro-structures (Move Analysis) and linguistic features of conclusion section of Research Articles (henceforth RAs) in Social sciences and Natural sciences have been investigated in this study.It has revealed variations in move structures and linguistic features of RAs conclusions across various disciplines in Pakistani context. For this study 50 RAs conclusions were selected randomly from different journals written by Pakistani writers. A new model has been proposed for the move analysis by following Yang & Allison's (2003) and Bunton's (2005) models for conclusion section. Linguistics features of conclusion sections have also been examined through MAT and Antconc software. This study would contribute a thorough understanding of the nature of conclusions of Pakistani RAs across various disciplines. It may be helpful for both writing instructors, whose purpose is to have their students succeed in using this component of genre, and to writing students, who are willing to take part in distinct discourse communities.
