| Abstract | As is well known that many decollement layers were developed in the Longmenshan thrust belt, Sichuan Basin, China. Through field investigation, explanation of seismic profiles and analysis of the balanced sections, we can divide the decollement zones into 3 categories: (1) the deep level decollement zones, including the crust-mantle decollement layer, intracrustal decollement layer, and presinian basal decollement layer. The main structural styles of their deformation are the crust-mantle decoupling detachment deformation, the basal ductile shear deformation, etc.; (2) the middle level decollement zones, including the Cambrian-Ordovician decollement layer, the Silurian decollement layer, etc., the main structural styles of their deformation are the isopachous fold, the angular fold, the saddle structure, and the combination styles of them; and (3) the shallow level decollement zones, including the Xujiahe Formation decollement layer of Upper Triassic and the Jurassic decollement layers, the main structural styles of their deformation are the thrust-nappe tectonic, the pop-up, the triangle zone, the duplex, etc. Multi-level decollement zones not only made the Longmenshan thrust belt develop many different deformation styles from deep place to shallow place, but also made some local areas have the superimposition of the tectonic deformation apparently. This study indicates that the multi-level decollement zones have a very important effect on the shaping and evolution of the Longmenshan thrust belt. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
