D/H variation in terrestrial lipids from Santa Barbara Basin over the past 1400 years: A preliminary assessment of paleoclimatic relevance
Santa Barbara Basin paleoclimatic relevance
2014/4/8
We analyzed D/H ratios of common terrestrial leaf wax lipids in a 1400 year sediment core from the Santa
Barbara Basin (SBB) to test whether they accurately record terrestrial climate in Southern Cal...
Paleoclimatic reconstructions in western Canada from boreholetemperature logs: surface air temperature forcing and groundwater flow
paleoclimatic western Canada boreholetemperature
2008/11/10
Modelling of surface temperature change effect on temperature vs.~depth and temperature-depth logs in Western Canada Sedimentary Basin show that SAT (surface air temperature) forcing is the main driv...
East Asian Monsoon and paleoclimatic data analysis: a vegetation point of view
East Asian Monsoon paleoclimatic data analysis vegetation
2008/10/30
First we review several syntheses of paleodata (pollen, lake-levels) showing the climate variations in China and Mongolia from the last glacial maximum to Present and in particular the precipitation i...
Changes in C3/C4 vegetation in the continental interior of the Central Himalayas associated with monsoonal paleoclimatic changes during the last 600 kyr
Changes in C3/C4 vegetation in the continental interior of the Central Himalayas associated with monsoonal paleoclimatic changes during the last 600 kyr
2008/10/29
A continuous lacustrine sediment core obtained from the Kathmandu Valley in the Central Himalayas revealed that cyclical changes in C3/C4 vegetation corresponded to global glacial-interglacial cycles ...
OLIGOCENE CLAY MINERALOGY OF THE LINXIA BASIN:EVIDENCE OF PALEOCLIMATIC EVOLUTION SUBSEQUENT TO THE INITIAL-STAGE UPLIFT OF THE TIBETAN PLATEAU
China Clay Minerals Linxia Basin Oligocene Palygorskite Tibetan Plateau Uplift
2011/11/11
The clay mineral content of the Oligocene sediments in the Linxia basin has been investigated using X-ray diffraction, scanning electron microscopy, and high-resolution transmission electron microscop...
Using empirical mode decomposition to correlate paleoclimatic time-series
empirical mode decomposition paleoclimatic time-series
2009/12/30
Determination of the timing and duration of paleoclimatic events is a challenging task. Classical techniques for time-series analysis rely too strongly on having a constant sampling rate, which poorly...
Supergene Origin of the Lastarria Kaolin Deposit, South-Central Chile, and Paleoclimatic Implications
Chemistry DTA Fluid Inclusions Gibbsite Hydrogen Isotopes Hydrothermal Illite Kaolinite Origin of Kaolin Oxygen Isotopes Weathering
2011/12/7
Abstract: The residual kaolin deposits near Lastarria, South-Central Chile, were formed by weathering of subvolcanic quartz porphyry stocks, which intruded the metamorphic basement of the Coastal Cord...
