Transient time for compressional and shear waves are recorded for each stressed core sample
before water saturation.
Designed to rapidly identify mineral constituents in drill core samples
as they emerge from the earth, this patent pending instrument provides a significant business opportunity for MASTInc to work with pre-production mineral exploration companies.
He said that the violence of the impact, followed by huge waves, roiled the Gulf of Mexico so much that it is unlikely to find clear core samples
X-rays, the usual technique for studying core samples
, do not make this differentiation.
The team, on board the survey vessel Greatship Maya, will gather core samples
, some of which will reach down to 150m (490ft) below the seabed.
have shown that some North American dune fields that scientists thought had been frozen since the last ice age actually have been on the move during the past few centuries.
When university botanist Paul Buck takes core samples
of sugar maple trees, there's a good chance his work might be interrupted by the buzzing posterior of a diamondback rattlesnake or the midsummer tantrum of a buffalo bull.
It is therefore essential that representative core samples
The researchers then looked at variations in the snowfall during that period and compared them with changes in precipitation recorded in deeper core samples
spanning as many as 400 years.
During its first 90 days on Mars, the rover will stick close to the lander, gathering samples, included core samples
it will drill from solid rock, as quickly and efficiently as possible.
Drill core was being logged and core samples
collected based on geologic contacts.
The magnitude of the tampering with core samples
that we believe has occurred and resulting falsification of assay values at Busang, is of a scale and over a period of time and with a precision that, to our knowledge, is without precedent in the history of mining anywhere in the world.
The researchers analyzed 20 core samples
from the floor of the Bering and Chukchi Seas.
will be used for metallurgical testing in order to identify a beneficial copper extraction technique in the oxide mineralized zones.
Lead concentrations in core samples
from when Greek civilization flourished over 2,500 years ago rival those found in segments from Roman times.
