The Indus Fan, located in the Arabian Sea, contains bulk of sediment eroded from Western Himalaya and Karakoram. Scientific drilling Laxmi Basin by International Ocean Discovery Program (IODP) recovered a discontinuous erosional record for River drainage dating back to at least 9.8 Ma, with single sample 15.6 Ma. We dated detrital zircon grains U-Pb geochronology reconstruct how erosion pattern...

In an earlier paper^ I described the new genus Brooksma from a series of sediments in southeastern Alaska tentatively referred to the upper Silurian. In that paper will be found a brief discussion of the faunal affinities of the series. A more detailed study of the Brooksina fauna together with the famias of lower and liighei horizons strengthens the belief that the formations in question shoul...

Inland glacier and lake dynamics on the Tibetan Plateau (TP) and its surroundings over recent decades are good indicators of climate change and have a significant impact on the local water supply and ecosystem. The glacier and lake changes in Karakoram are quite different from those of the Himalayas. The mechanisms of the complex and regionally heterogeneous behavior of the glacier and lake cha...

An assessment of glacier shrinkage (reduction of area) for all of HighMountain Asia requires a complete compilation of measured rates of change and also a methodology for objective comparison of rates. I present a compilation from 155 publications reporting glacier area changes, and also a methodology that overcomes the main obstacles hindering comparison. Glacier areas are not always assigned ...

The recent dynamic behaviour of Karakoram glaciers is expected to differ from that shown by glaciers in the central and eastern Himalaya because of regional variations in precipitation and temperature trends. However, there are insufficient quantitative data to support or confute such hypotheses. We present velocity data covering the period 1993–2008 for Baltoro Glacier, one of the longest glac...

Accumulation gain is essential for mass balance of valley glaciers in the Karakoram Himalayas. The higher elevation of this area received snowfall(>1000 cm · yr−1) annually, while the snowfall occupies 95% of total precipitation (75-150 cm · yr−1). Meanwhile, the air temperature ranging from -20 to -40 °C, during DecemberFebruary, is also very suitable for accumulation of glacier mass. We choos...

By matching of repeat optical satellite images it is now possible to investigate glacier dynamics within large regions of the world and also between regions to improve knowledge about glacier dynamics in space and time. In this study we investigate whether the negative glacier mass balance seen over large parts of the world has caused the glaciers to change their speeds. The studied regions are...

Glaciers in China are primarily located in the Tibetan Plateau (TP) and surrounding high mountains. The Chinese Glacier Inventory indicates that there are 46 377 glaciers in western China. Meteorological records indicate that air temperature in western China has risen by 0.28C per decade since 1951, and 1998 was the warmest year; precipitation in the region increased by 5–10% per decade from 19...
