Deformation at the front of the Himalayan thrust wedge is focused along the Main Frontal Thrust (MFT) resulting in shortening of the Neogene foreland basin deposits since the Pleistocene. This research investigates variations in structural style along the MFT in the Dang Valley region, west-central Nepal, and how these variations affect the distribution of modern wedge-top sediment depocenters. Four kinematic models and cross sections were constructed to evaluate plausible geometric and kinematic histories. Three structurally distinct regions are recognized: 1) the western section distinguished by north-dipping imbricate thrusts; 2) the central section characterized by south-dipping back thrusts that structurally confine the southern margin of the Dang Valley; and 3) the eastern section distinguished by north-dipping imbricate thrusts and south-dipping back thrusts that form along a shallow detachment resulting in a composite pop-up structure. Neogene shortening estimates across the study area range from 47% to 40%. Derived shortening rates that range from 20 mm/yr to 14 mm/yr are consistent with modern geodetically derived India-Eurasia convergence rate across the Himalaya. This implies that in this region most of the shortening since initiation of tectonic activity ca. 2.3 Ma, has been accommodated between the Main Boundary thrust (MBT) and the MFT along a single basal detachment known as the Main Himalayan Thrust (MHT). Two transfer zones are the most plausible features to explain the along-strike variation in structural style within the study area. From west to east these are: 1) the West Dang Transfer Zone (WDTZ), interpreted to be a complex zone of strike-slip faults and lateral ramps which may transfer strain to a deeper detachment level to the east; and 2) the Masot Khola Transfer Zone (MKTZ), interpreted to transfer strain along a lateral ramp to a deeper basal detachment and a secondary shallow detachment surface to the east. The results of this study suggest there is a relationship between changes in structural style and wedge-top development. Abrupt changes in distribution of wedge-top sediments are coincident with changes in structural style.

The outer parts of collision mountain belts are commonly represented by fold and thrust belts. Major advances in understanding these tectonic settings have arisen from regional studies that integrate diverse geological information in quests to find and produce hydrocarbons. Drilling has provided tests of subsurface forecasts, challenging interpretation strategies and structural models. This volume contains 19 papers that illustrate a diversity of methods and approaches together with case studies from Europe, the Middle East and the Asia-Pacific region. Collectively they show that appreciating diversity is key for developing better interpretations of complex geological structures in the subsurface – endeavours that span applications beyond the development of hydrocarbons.

Fold-and-thrust belts occur worldwide, have formed in all eras of geological time, and are widely recognized as the most common mode in which the crust accommodates shortening. Much current research on the structure of fold-and-thrust belts is focused on structural studies of regions or individual structures and on the geometry and evolution of these regions employing kinematic, mechanical and experimental modelling. In keeping with the main trends of current research, this title is devoted to the kinematic evolution and structural styles of a number of fold-and-thrust belts formed from palaeozoic to recent times. The papers included in this book cover a broad range of different topics, from modelling approaches to predict internal deformation of single structures, 3D reconstructions to decipher the structural evolution of groups of structures, palaeomagnetic studies of portions of fold-and-thrust belts, geometrical and kinematical aspects of Coulomb thrust wedges and structural analyses of fold-and-thrust belts to unravel their sequence of deformations--

Compressional Tectonics A synthesis of current knowledge on collisional and convergent plate boundaries worldwide Major mountain belts on Earth, such as the Alps, Himalayas, and Appalachians, have been built by compressional tectonic processes during continent-continent and arc-continent collisions. Understanding their formation and evolution is important because of the hazards associated with convergent and collisional plate boundaries, and because these mountain belts contain resources such as precious metals, rare earth elements, oil, gas, and coal. Compressional Tectonics: Plate Convergence to Mountain Building reviews our present-day knowledge of the tectonic evolution of the Alpine-Himalayan and Appalachian belts. Volume highlights include: Overview of terminology relating to compressional and contractional tectonics Discussion of subduction zone dynamics Debates over the timing of the collision and convergence of particular subduction and suture zones Examples of the different stages in the development of orogenic belts This book is one of a set of three in the collection Tectonic Processes: A Global View. The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.

The Indian National Science Academy was established in January 1935 with the objective of promoting science in India and harnessing scientific knowledge for the cause of humanity and national welfare. In 1968 it was designated as the adhering organisation in India to the International Council for Scientific Union (ICSU) on behalf of the Government of India. Over the years, the Academy has published a number of journals, volumes, biographical memoirs, etc. The year 2009–2010 will be specially celebrated to mark the Platinum Jubilee of the Academy. Many programmes are planned in different centres in India on this occasion. In addition, the Academy has decided to publish a number of special volumes on different s- jects ranging from earth sciences to life sciences. This volume is on Physics and Chemistry of the Earth’s Interior. One of the main objectives of geophysicists is to establish the internal structure of the earth as revealed by seismic tomography. It is also their primary goal to correlate geophy- cal data to reveal thermal and chemical state of the crust, mantle and core of the earth. In - der to interpret seismic velocities and associated density and elastic properties in terms of mineralogical and petrological models of the earth’s interior, thermodynamic and hi- pressure temperature data from mineral physics are essential. With the advent of different types of multi-anvil and laser-heated diamond anvil equipment, it is now possible to simulate conditions prevalent even in the lower mantle and core of the earth.

K.R. McClay Department of Geology, Royal Holloway and Bedford New College, University of London, Egham, Surrey, England TW20 OEX. Since the first Thrust and Nappe Tectonics Conference in London in 1979 (McClay & Price 1981), and the Toulouse Meeting on Thrusting and Deformation in 1984 (Platt et al. 1986) there have been considerable advances in the study of thrust systems incorporating new field observations, conceptual models, mechanical models, analogue and numerical simulations, together with geophysical studies of thrust belts. Thrust Tectonics 1990 was an International Conference convened by the editor and held at Royal Holloway and Bedford New College, University of London, Egham Surrey, from April 4th until April 7th 1990. There were one hundred and seventy participants from all continents except South America. The conference was generously sponsored by Brasoil U.K. Limited, BP Exploration, Chevron U.K. Limited, Clyde Petroleum, Enterprise Oil, Esso Exploration and Production UK Limited, and Shell U.K. Exploration and Production. One hundred and five contributions were presented at the meeting, - seventy six oral presentations (together with poster displays) and an additional twenty nine posters without oral presentation (McClay 1990, conference abstract volume).
