In each experiment, a core sample
was first fully saturated with water.
Rather than using models, array sensor readings or personal expertise to decide where to make a series of test holes, geologists can now utilize this instrument to rapidly access the mineral makeup of the core samples
as soon as they are extracted.
Corell, assistant director for Geosciences of the National Science Foundation, said the core samples
are the strongest evidence yet that an asteroid impact caused the extinction.
were transported to the "Centro Experimental Chihuahua Laboratory of Servicio GeolE[thorn]gico Mexicano" for analysis.
All core samples
are split in half using a diamond saw and sealed in secure packages, shipped by bonded air carrier from Red Lake to ALS Chemex in Thunder Bay for preparation, and to ALS Chemex in North Vancouver for AU-AA62 assay (gold by fire assay with AA finish) and ME-MS61 47 element analysis (4 acid dissolution and ICP-MS).
Their core samples
dated back as much as 8,000 years.
WT) announced today that it has completed the relogging of approximately 10,000 meters of core samples
from its Junin copper prospect, located in Northern Ecuador.
Now, extensive core samples
gathered on leg 145 of the Ocean Drilling Program may prompt oceanographers to reexamine the connection between Pacific volcanism and the northern hemisphere's deep freeze, says David K.
were crushed to pass a 10-mesh-size sieve, a 200- to 250-gram split was then pulverized to have no greater than 95% passing a 200-mesh-sized sieve to produce a homogenized sub-sample.
Smith in the university's department of geology and geophysics reports in the March GEOLOGY on the magnetic properties of core samples
taken from drill hole 504B, which penetrated 1,350 meters into the crust during Leg 83 of the Deep Sea Drilling Project (DSDP).
The core samples
are being transported to laboratory facilities for analysis, including hydrocarbon assay.
Preliminary metallurgical studies are nearing completion from drill core samples
of the M2 Zone.
