This book was released on 2023-11-25 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laterite deposits are known to occur extensively on Indian Peninsula having derived from varied geological formations of different ages. These deposits are derived from khondalite and Charnockite groups of rocks in the Eastern Ghats, granite gneisses in Karnataka, Vindhyan sandstones in Utter Pradesh, Deccan Trap basalts in Madhya Pradesh, Gujarat and Maharastara, Gondwana sand stones in Madhya Pradesh, Sirban lime stones in Jammu and clastic sediments in Gujarat. Laterite deposits associating with all these rock types occur as cappings or blankets. Laterites associated with a particular geological formation show compositional variation with altitude. Enrichment of aluminium generally takes place on the broad topped and gently sloped hills, whereas enrichment of iron on slopes of hills and on plain areas, even though the process of lateritisation has taken place on the same type of rock and in the same climatic zone on mega scale. The iron-rich laterites confined to a specific altitudinal range in the study area has led the author to make thorough investigation on these laterite deposits with reference to their mode of occurrence, mineralogy, mineral alteration, geochemical behavior of elements and various other processes that are in operation during lateritisation.

Download or read book Laterites of the Bengal Basin written by Sandipan Ghosh and published by Springer. This book was released on 2019-06-24 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Brief analyses and discusses the laterites in the Bengal Basin. The book highlights: (1) the definition, identification and classification of ferruginous materials, (2) the mode of laterite formation and its other horizons, (3) processes and theories of lateritisation, (4) determination of laterite ages, (5) recognition of palaeogeomorphic and palaeoclimatic significance and (6) geo-chronology and reconstruction of former lateritized landscapes. The chapters cover the tectono-climatic evolution of north-south laterite profiles of the north-western Bengal Basin on the Rajmahal Basalt Traps, Archean Granite-Gneiss, Gondwana Sandstones, Palaeogene Gravels and Older Palaeo-Deltaic Alluvium. The book uses advanced field-based studies, quantitative analysis and thematic mapping to cover various areas of palaeogeography and regolith geology of the Bengal Basin in connection with laterite genesis, palaeoweathering, tectonic geomorphology, Quaternary geomorphology and pedogeomorphology. It introduces laterites as a potential stratigraphic marker in Indian geology by explaining their palaeogeomorphic and palaeoclimatic significance. This Brief is a comprehensive resource to researchers, students and academicians of geography, geomorphology and geology working on laterites.
Download or read book Subsoil Constraints for Crop Production written by Teogenes Senna de Oliveira and published by Springer Nature. This book was released on 2022-08-03 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will address the major subsoil physical and chemical constraints and their implications to crop production; Plant growth is often restricted by adverse physical and chemical properties of subsoils yet these limitations are not revealed by testing surface soils and hence their significance in crop management is often overlooked. The major constraints can be physical or chemical. Physical limitations such as poor/nil subsoil structure, sandy subsoils that do not provide adequate water or gravelly subsoils and, etc. On the other hand, chemical constraints include acidity/alkalinity, high extractable Al or Mn, low nutrient availability, salts, boron toxicity and pyritic subsoils. Some of these constraints are inherent properties of the soil profile while others are induced by crop and soil management practices. This aim of this book is to define the constraints and discuss amelioration practices and benefits for crop production. This book will be of interest to readers involved with agriculture and soil sciences in laboratory, applied or classroom settings.

This book was released on 2018-09-17 with total page 1002 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interpretation of Micromorphological Features of Soils and Regoliths, Second Edition, provides researchers and students with a tool for interpreting features observed in soil thin sections and through submicroscopic studies. After an introduction and general overview, micromorphological aspects of regoliths (e.g., saprolites, transported materials) are highlighted, followed by a systematic and coherent discussion of the micromorphological expression of various pedogenic processes. The book is written by an international team of experts in the field, using a uniform set of concepts and terminology, making it a valuable interdisciplinary reference work. The following topics are treated: freeze-thaw features, redoximorphic features, calcareous and gypsiferous formations, textural features, spodic and oxic horizons, volcanic materials, organic matter, surface horizons, laterites, surface crusts, salt minerals, biogenic and pedogenic siliceous materials, other authigenic silicates, phosphates, sulphidic and sulphuric materials, and features related to faunal activity. The last chapters address anthropogenic features,archaeological materials and palaeosoils. - Updates the first exhaustive publication on interpretation of micromorphological features, with some new chapters and with a larger number of additional references - Covers related topics, making micromorphology more attractive and accessible for geomorphologists, archaeologists and quaternary geologists Includes thematic treatment of a range of soil micromorphology fields and broadens its applications - Features input from a multi-disciplinary team, ensuring thorough coverage of topics related to soil science, archaeology and geomorphology

Download or read book Regolith Exploration Geochemistry in Tropical and Subtropical Terrains written by C.R.M. Butt and published by Elsevier. This book was released on 2015-12-04 with total page 644 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of exploration geochemistry has increased enormously in the last decade. The present volume specifically addresses those geochemical exploration practices appropriate for tropical, sub-tropical and adjacent areas – in environments ranging from rainforest to desert. Practical recommendations are made for the optimization of sampling, and analytical and interpretational procedures for exploration according to the particular nature of tropically weathered terrains. The underlying theme is the recognition that regions between 35°N and 35°S in particular have a common history of deep chemical weathering and lateritization during the late Mesozoic and early Tertiary. This has had a profound and lasting effect, so that the surface geochemical expressions of mineralization throughout these regions have many similar features, with local modification due to more recent weathering under changed climates. The volume discusses the data derived from numerous research and case studies in terms of exploration and dispersion models based on the weathering and geomorphological history. The models permit valid comparisons between equivalent terrains that may be geographically widely separated and situated in quite different climatic environments. The basis of the volume is to view geochemical dispersion within the context of a genetic understanding of the evolution of landforms and the regolith (i.e. landscape geochemistry) and to develop exploration procedures based on this understanding. This book should be of interest to exploration geochemists, economic geologists, soil scientists, geomorphologists and environmental geochemists.
