Geology Today, 2007
With increasing interest in climate change and other issues associated with the history of the environment and anthropogenic evolution there is an ongoing requirement to investigate the Earth's natural systems. A key approach is for scientists to look back into geological time, perhaps millions of years, to see how the world has reacted to natural ...

Plains Anthropologist, 2005
The vegetative history of eastern North Da kota is broadly known from pollen and multi-proxy investigations of lake basins from across the re gion (Clark et al. 2001; Dean and Schwalb 2000; Wright et al. 2004). These records suggest that parkland or savanna rapidly developed following glacial retreat and subsequent drainage of glacial Lake Agassiz to ...

Phytoliths and their applications
2014Phytoliths are biomineralizations present in cell walls and/or inter or intracellular spaces of plant tissues. Although the term "phytolith" refers to different amorphous and/or mineral deposits compounded by different elements, such as calcium or silicon, this book focuses on amorphous biogenic silica (SiO2.nH2O), also known as opal phytoliths, silica
