I am absolutely beholden by my Lord’s generosity in this effort. Praises be to Holy Prophet for He is a beacon as I pace on in my life and work. First of all I want to acknowledge my supervisor Dr. Mohammad Tahir Shah, Professor, National Centre of Excellence in Geology, University of Peshawar, Pakistan without whom I may have not been able to compile this research thesis than I am indebted to co-supervisor Dr. Sardar Khan, Associate Professor, Department of Environmental Sciences, University of Peshawar, Pakistan for his kind support during the entire period of my PhD. I like to gratitude my foreign supervisor Dr. Andrew Meharg, Professor, Department of Soil and Environmental Sciences, Institute of Biological Sciences, University of Aberdeen, United Kingdom for his help in completing ICPMS work for my thesis. I am thankful to external evaluators and internal viva examiners for their kind suggestions to improve the quality of research presented in this thesis. Thanks are also due to Professor Dr. M. Asif Khan, Director, National Centre of Excellence in Geology, University of Peshawar, Peshawar, Pakistan for facilitating the research work during entire period of my PhD program. My gratitude goes to Dr. Tazeem Khan, Dr. Rubina Bilques, Dr. Samina Sadique, Dr. Fazal-i-Rabi, Mrs Seemi and Mrs Farhi Sahar, whose moral support always boosted my energies. Special thanks are to Mr. Muhammad Tariq (Lab technician) and Mr. Bilal (Lab Attendant) for their cooperation during entire laboratory work. I am highly obliged to my teachers and colleagues of all university especially who are working in National Centre of Excellence in Geology, University of Peshawar, Pakistan who appreciated the compilation of this Thesis. I am thankful to all people of Attock and Haripur Basins for helping me during field survey, especially local community of remote villages. My sincere thanks are to all staff, scientists and professors of University of Aberdeen, United Kingdom, especially Prof. Dr. Adam Price, Prof. Dr. Angel, and Mrs. Claire Deacon for their cooperation, technical assistant and provision of laboratory facilities. I am also thankful to my brother Assistant Professor Dr. Iftikhar Ahmed, Chairman, Department of Mathematics, University of Gujrat, Pakistan for his encouragement to do such type of unique research work. My sincere thanks are for all my precious friends and colleagues (Safia Tabassum, Khalid Latif, Wajid Ali, Muhammad Ali, Azra Yaseem, Reema Fida, Humaira Fida, Humaira Gul, Shahia Khattak, Anne Marie, Zainab, Faiz, Dr. Lorna, Dr. Nimbe Ewald, Tanveer, and Gillian Kerr) for their forbearance, helpful and enjoyable company. Nevertheless, it’s the inspiration that I derived from the unconditional love, care, and prayers of my parents, in laws, husband Dr. Muhammad Qasim Hayat, Assistant Professor, Atta-ur-Rehman School of Applied Bio-Sciences (ASAB), NUST, Islamabad, Pakistan, brothers, sisters, nephews, nieces and my children (Sabaina and Mahdi Hayat) that have propelled me as far as I have triumphed.
