b Rose diagram showing orientation of lineaments Open image in new window Fig. 8 a The Jamini River flowing through confined valley setting in Bundelkhand Granitic Complex with occasional flood plain pockets having bedrock, boulder, and gravel.
Water depth (cm), water velocity (cm/s), and percent substrate type (bedrock, boulder, cobble, gravel, sand, and silt) were measured at five points across each transect.
Rivers originating at or above the fall line tend to have high gradient and a substrate mainly consisting of bedrock, boulders, and gravel.
At each site, small sized boulders (ca. 0.1×0.1 m) densely covered with recruits of C. babata were collected from zones of low survival probability (i.e., small, shallow boulders), broken into small fragments holding 1 2 individuals, and transplanted in plots of 5 individuals using epoxy putty onto more stable bedrocks (boulders >10 m3 in size or eroded rocky platforms).
At some fifteen hundred and fifty intersections, according to Randel's notes, the men set "monumental stones"; at nearly a hundred others, where they encountered bedrock or boulder, they placed iron bolts.
In general, the ages of paired bedrock and boulder samples are in close agreement (r2 = 0.72).
Eleven of the fourteen paired bedrock and boulder samples are indistinguishable at 1σ; this concordance indicates that subglacial erosion rates are sufficient to remove most or all 10Be accumulated during previous periods of exposure, and that few, if any, nuclides are inherited from pre-Holocene interglaciations.
Dark features such as exposed bedrock and boulders catch rays, causing local temperatures to rise.
We measured in situ cosmogenic 10Be in 16 bedrock and 14 boulder samples collected along a 40-km transect outside of and normal to the modern ice margin near Sikuijuitsoq Fjord in central-west Greenland (69°N).
Substrate composition was determined by size tall, performed by placing a finger into the water and classifying the size of the particle first touched as bedrock (>4000 mm), boulder (250 4000 mm), cobble (64 250 mm), coarse gravel (16 64 mm), fine gravel (2 16 mm), sand (0.06 2.00 mm), fines (<0.06 mm), wood, hardpan (firm, consolidated fines), or other.
