In a recent BBC news feature, the UK’s Open University made headlines for being the only institution in the country granted access to lunar dust returned by China’s Chang’e 5 mission - the first lunar sample return in nearly 50 years. The tiny, 60mg sample of Moon rock is now housed in a secure facility in Milton Keynes, where ...
Vista Clara is pleased to introduce a new addition to our family of high-resolution Dart™ NMR logging tools: Helios Trek™. Helios Trek is a portable NMR soil core analyzer that can be used in both the laboratory and the field. This rugged and portable system is operated by the Dart™ NMR Control Unit and enables NMR measurement from freshly extracted soil samples with a spatial ...
Mercury is one of the most universal pathfinders of many types of ore deposits and is widely used for geochemical exploration with sampling rocks, soils, and sediments. Moreover, this volatile element can also create gaseous haloes over ore bodies that can be detected by ultrasensitive detectors such as the portable RA-915M mercury analyzer. ...
NMR measurements also provide the ability to unambiguously differentiate moveable groundwater that resides in large pores (sands, gravels and large fractures) from immovable water in small pores (silts, clays and small pore structures in rock matrices). This webinar will provide a high-level review of how the basic NMR measurement works, and how the amplitude and time decay ...
Pigeon Spring had elevated uranium levels in recent samples from 2012-2014 (73-92 micrograms per liter), compared to other perched springs in the same drainage area (2.7–18 micrograms per liter), and was proportionally elevated in samples collected prior to mining operations at the nearby Pigeon Mine. ...
” Carbon dioxide would have to be injected into rocks in liquid form, to replace the natural brines already in the rock pores and crevices. ...
Since the 1990s, X-ray computed tomography (CT) has become increasingly popular for its ability to yield big insights from tiny rock samples. But the volume of data produced from CT scanners is anything but tiny, and that makes sharing and storing the files a challenge. In an effort to address this issue and foster collaboration in an area where there is ...
Because of the new translation method, luminescence measurements on rock samples can give unique recent information about past temperatures, dating back 10,000 to 100,000 years. ...

Variable speed, fixed angle rocker Side to side rocking motion Variable speed: 7.5 to 30 rpm Fixed angle: 7° tilt Integral digital timer, 1 min to 24 hours, with automatic switch-off 215 x ...
It measures the effectiveness of water or gas injected into an oil-bearing rock sample to displace oil. This can be used to assess the potential for water flooding in an oil field. ...
As a Contributor the person or company will receive a tax deductable receipt and a qualifying donation of more than $5,000 will entitle the doner to a Grant each month of certain Geologic Specimens from the site these will include rock samples and the doners portion of the recovered gold from the reclamation site. ...
“We use the most advanced methods available to analyze asbestos in various types of samples, including water, soil, rock, air, settled dust, building materials, and ...
SGS is pleased to announce the opening of our new Mobile Sample Preparation Unit (MSPU) in Ouagadougou, Burkina Faso. The MSPU expands our rock and drillcore sample preparation capacity in Burkina Faso, ahead of our major new laboratory complex being built in Ouagadougou. The MSPU will immediately add an additional 600 ...

The objective of the investigation should be to identify and locate, both horizontally and vertically, significant soil and rock types and groundwater conditions present within a given site area and to establish the ...
Scope 1.1 This guide covers information, including flow charts, for field personnel to follow in order to collect samples from drums and similar containers. 1.2 The purpose of this guide is to help field personnel in planning and obtaining samples from drums and similar containers, using equipment and techniques that will ensure that ...

Scope 1.1 This test method covers the determination of the expansion of a specimen of carbonate rock while immersed in a solution of sodium hydroxide (NaOH) at room temperature. The length changes occurring during such immersion indicate the general level of reactivity of the rock and whether tests should be made to ...
Although the P-wave velocity is a good indicator of the type of soil or rock, it is not a unique indicator. Table 1 shows that each type of sediment or rock has a wide range of seismic velocities, and many of these ranges overlap. ...
This presentation describes a comprehensive approach for determining the nature, extent, transport and fate of contaminants at industrial sites on fractured rock, with emphasis on sedimentary rock, referred to as the Discrete Fracture Network (DFN) approach. ...
Industrial coal tar pitch for example is solid at ambient temperature, softens around 100-130°C and becomes fully liquid at 180°C. When cooled down the tar sample becomes rock solid in seconds, making it difficult to clean flashpoint testing equipment and to continue with the measurements. ...
