Übersetzung für "Tongestein" in Englisch

Transported deeper and deeper by subsidence, under pressure and high temperature the clay was transformed into rock.

Opalinus is a clay formation that was formed from marine material deposited approximately 175 million years ago.

Aluminium silicate hydrous (kaolin) is a purified white plastic clay composed of kaolinite, potassium aluminium silicate, feldspar and quartz.

The geoscientific background is based on the one hand on an evaluation of the geological investigations previously carried out by Nagra on deep geological disposal of HLW and L/ILW in Switzerland (investigation programmes in the crystalline basement and Opalinus Clay in Northern Switzerland, investigations of L/ILW sites in the Alps, research in rock laboratories in crystalline rock and clay); on the other hand, new geoscientific studies have also been carried out in connection with the site selection process.

It is partially a semidesert landscape, affected by pouring rains that shaped its plaster and clay terrain.

The claystones are very fine grained sedimentary rocks that were deposited directly in to the salty, shallow lake which occupied the Clayton Valley before drying up following the last ice age.

The implications of the data in T able 1 clearly indicate that the mineralogy of lithium mineralization in the surface samples from the Cypress property differs materially from other know n claystone hosted lithium resources including those at Kings Valley, Humboldt County, Nevada where a huge lithium resource is bound in the silicate clay mineral hectorite.

In spite of this, and the obvious presence of clays, these minerals do not appear to have affected the flotation to any great extent.

Beside salt and crystalline rock also argillaceous rock is considered as possible host rock for a nuclear waste repository.

The DBE Technology GmbH and Dynardo performed an analysis of the THM rock behaviour in response to artificial heating for the exploration of underground laboratories.

If the reservoir 2 is provided with clay rock, then the top clay layer on the inner walls of the reservoir 2, for example, may be periodically removed and disposed of respectively, or conditioned, in order to remove the strongly contaminated clay layers and to continue the cleaning with a “fresh” clay layer, which can be applied again if needed.

Preferably, the clay and the clay rock respectively should be provided in such a way that it can be selectively replaced or removed when a predetermined amount of contaminated (radioactive) substances gets bound to it.

This validation study shows that the methodology used for the derivation of the sorption data bases for argillaceous rocks and bentonite produces reliable sorption values.

Arguments are presented that the main factor influencing sorption on argillaceous rocks is the phyllosilicate mineral content.

The ratio data above compares in a n effective way the chemistries of a synthetic brine made from surface outcropping claystones on the Cypress Dean p roperty with basin brines of the Clayton Valley.

The Company will assess all available and pertinent data for this latest land package to be able to determine what exploration programs could be initiated at the same time as Cypress is carrying out its planned Phase 3 drill program targeting lithium brines at the Company's Clayton Valley Project which will also include the drilling of shallow auger holes target ing areas of strongly lithium mineralized claystone s recently discovered at surface .

In other news, d etailed lithium extraction work on a series of mini- bulk samples of claystone taken from the Cypress – Pure Energy joint exploration project at the neighboring Glory P roject is con tinuing at SGS Labs in Canada.

This last observation cannot be explained so far but is comparable to experimental data from ANDRA (1999) on Callovo-Oxfordian claystones from the Meuse/Haute Marne site.

The focus of the bench test ing is to substantiate the recovery yield of lithium carbonate directly from the mineralized claystones using MDS's environmentally friendly process .

The term "claystones" as used here does not imply that the rock contain s clay minerals, only that they are very fine grained.

D rilling will focus on th e Zeus and Hades claim groups, where previously reported surface and sub- surface sample assay values ranged from 206 ppm to a high of 1,670 ppm lithium and averaged 780 ppm lithium within the claystones (see news released on July 22, 2016 and July 26, 2016).

The first project studies carried out by Nagra in this connection date back more than 20 years (Nagra 1980) and looked at the option of disposal in crystalline basement rock and clay.

In a previous report (Bradbury et al. 2010), a methodology was described for developing sorption data bases for argillaceous rocks, so called Generic Rock Sorption Data Bases.

Extensive sampling by Cypress at the Dean Project has identified strong lithium mineralization up to 3,700 ppm lithium (1.98% lithium carbonate equivalent) in a highly soluble uplifted lakebed mudstone and claystone in the 2 square kilometer Frontera Verde Zone that averages 1,500 ppm lithium (0.80% lithium carbonate equivalent) at surface . Outcropping lithium-rich mudstones at Dean Project:

A comparison between measured and predicted values for each case was then made.This validation study shows that the methodology used for the derivation of the sorption data bases for argillaceous rocks and bentonite produces reliable sorption values.
