Four decades of glacier mass balance observations in the Indian Himalaya
Understanding the glacier mass balance is necessary to explain the rate of shrinkage and to infer the impact of climate change. The present study provides an overview of the glacier mass balance records by gla...

Summary, Conclusions, and Future Prospects
This COLE volume describes and discusses the interaction of microbes with sediments since the earliest stromatolites were formed on Earth, around 3,500 Ma ago. One of the most significant areas of sedimentary ...

The Sulfur Cycle on the Early Earth: Implications for the Search of Life on Europa and Elsewhere
The search for life in the universe, especially on the Jovian satellite Europa, could benefit from our knowledge of the bacterial processing of sulfur on the early Earth. We know that sulfate respiring bacteri...

Meso-Neoproterozoic Stromatolites from the Indravati and Chhattisgarh Basins, Central India
The Meso-Neoproterozoic period is very significant for the diversification of the stromatolite taxa on Earth. Stromatolites have been used for the regional and global biostratigraphic correlations of the Prote...

Stromatolites, Organic-Walled Microorganisms, Laser Raman Spectroscopy, and Confocal Laser Scanning Microscopy of the Meso-Neoproterozoic Buxa Formation, Ranjit Window, Sikkim Lesser Himalaya, NE India
The Buxa Dolomite, a Meso-Neoproterozoic formation composed largely of stromatolitic cherty carbonate, is well developed in the Ranjit River section, south and west Sikkim, NE Lesser Himalaya. The formation is...

Cave Geomicrobiology in India: Status and Prospects
The subsurface of the Earth is one of the major habitats and contains a significant proportion of microbial life (Whitman et al., 1998; Ghiorse, 2008; Roussel et al., 2008). However, our overall knowledge abou...

Morphological Changes in Microscopic–Megascopic Life and Stromatolites Recorded During Late Palaeoproterozoic–Neoproterozoic Transition: The Vindhyan Supergroup, India
The Palaeoproterozoic to Neoproterozoic era (1,700–542 Ma) is a significant time of transition, reflecting major biotic events in the evolution of life at global level. This time has been marked by the dominat...

Ediacaran Krol Carbonates of the Lesser Himalaya, India: Stromatolitic Facies, Depositional Environment and Diagenesis
Upper Krol Formation (Krol D Member) is a typical Ediacaran (Terminal Neoproterozoic) microbial carbonate facies. It is well developed in the Lesser Himalayan Krol belt extending from the Solan in the Himachal...

Microbialites as Markers of Biotic and Abiotic Events in the Karst District, Slovenia and Italy
Microbialite units are commonly found within the Mesozoic–Tertiary carbonate succession of the Karst District of Slovenia and Italy. They record environmental conditions, which are linked with both local and g...

Proterozoic Unicellular and Multicellular Fossils from India and Their Implications
A comparative study of possible genesis of life on planet Earth and Mars reveals that similar conditions would have been present on Mars supporting a probable occurrence of unicellular Martian microfossils and...
