- n. Plural form of sediment.
“Abundant tiny particles of diamond dust exist in sediments dating to 12,900 years ago at six North American sites, adding strong evidence for Earth's impact with a rare swarm of carbon-and-water-rich comets or carbonaceous chondrites, reports a nine-member scientific team.”
“And it was discovered in sediments that are around 36 million years old.”
“The eastern half of Marajó island, on older Tertiary sediments, is covered by flooded savanna (campo) and humid terra firme forest, the forest being fairly homogeneous and distinct from the inundated forest in the west.”
“The evidence gleaned from fossilised mites, preserved in sediments at a lake about 50km (30 miles) from the Inca capital of Cuzco, has shown how the great empire increased in size and complexity in the early 15th century.”
“There are three principal geomorphologic types in the ecoregion: alluvial plains of recent origin, low mountains formed by the relatively recent dissection of sediments from the Tertiary and Pleistocene periods, and the complexes in mountain areas consisting of mesozoic rocks.”
“Seashells are not found in sediments that were not formerly covered by sea. so how did the sediments get from the top of the mountain to the valley without ever touching water? plus, the floods had to come from the ocean (saltwater mammel). what kind of floods were they? the floods had to be in the valley. this dosnt make sense.”
“Seashells are not found in sediments that were not formerly covered by sea.”
“Core-drilling [I wrote about this in detail in "Sedimentology Gone Wild: The Onion-Layer Theory of Time Travel," _Analog, _ September 2002, pp. 52-63.] allows sedimentologists to determine the climate history of the Sahara, both by the quantity of dust and by the isotope ratios of oxygen trapped in the sediments, which is an indicator of the temperature at which they were deposited.”
“The removal of the sediments is a little trigger, a little push, the last drop in the bucket that you need to get the fault going," said Eric Calais, a professor of geophysics at”
“The research will help identify where and when the sediments are a source for nitrogen and phosphorus.”
