Rivers of South Asia carry dissolved inorganic phosphorus (DIP) at levels far greater than many of the world’s rivers such as the Amazon River and European rivers on whose phosphorus data average rates of DIP exported to the oceans are largely based. Similarly, all the major river systems in South Asia have sedimentary phosphorus values that are considerably higher than the world average. Unlike the Amazon or other large river system for which extensive data are available, organic phosphorus contributes very little to the total sedimentary phosphorus pool in South Asian rivers. Trapping of enormous amounts of sediment in the vast alluvial belts in the northern part of South Asia indicate that very little of the sedimentary phosphorus transported by these rivers is likely to be exported to the adjacent marine environment.

Marine Authigenesis: From Global to Microbial
This volume is a collection of 33 state-of-the-art papers focusing on various aspects of authigenic and diagenetic marine minerals and related global elemental cycling. The commingling of the various studies of authigenic minerals in this volume, including the most recent advances in knowledge concerning the occurrence and origins of phosphorites, glauconites, dolomites, siderites, manganese-iron associations, barites, ironstones, and other marine chemical sediments/sedimentary rocks of early authigenic/diagenetic origin, is partly the result of the increasing awareness that there are many overlaps, even direct co-associations, between different authigenic minerals, both in time, space, and genesis. Taken together, this compilation represents a holistic approach towards marine authigenesis that considers the integrated whole more than the simple sum of its parts.
