Overall, both host rocks show a good barrier function.
Mineralization is related to at least two quartzveins associated with shear zones within basaltic host rocks.
The host rocks are commonly shale, and to a lesser extent, sandstones.
The characterisation of the deep aquifers alsomakes an important contribution to understanding the situation in the host rocks, for example with regard to porewater salinity.
Overall, both host rocks show a good barrier function, but the Effingen Member shows clear disadvantages compared to the Opalinus Clay.
Drilling identified sulphide mineralization as disseminated and stringer occurrences in mafic(up to 3% sulphide) and ultramafic(peridotite,up to 1% sulphide) host rocks.
Ibague and Fresno both have similar host rocks and igneous bodies to those found at Cajamarca but only limited regional investigations have been conducted.
The dominant ore mineral is coarse- grained chalcopyrite(with minor magnetite, pyrite, pyrrhotite and gold) which occurs within quartz veins,breccia fill and as disseminations in host rocks.
Both host rocks are practically identical in terms of release from the near-field but the Effingen Member is significantly behind the Opalinus Clay in terms of release from the confining units.
The Malm and Muschelkalk aquifers in Northern Switzerland form the regional deep aquifers above and below the host rocks and thus define the maximum extent of the potentially effective containment rock zone.
Drilling has established that Keystone host rocks are the same as, or very similar to, the units that comprise the primary host units within the Cortex District to the north.
Blackheath also drilled two initial holes BO 3 and BO 4 which did not intersect the Santa Helena Breccia, due to the dip of thecontact of the breccia body with adjacent granitic host rocks and the inclination of the drill hole.
Research on the interactions of radionuclides with dominant microorganisms originating from potential host rocks and barrier material of nuclear waste repositories including the speciation of actinides in prokaryotic microorganisms and single-celled eukaryotic organisms.
The question arises of what would be the requirements and assets of a universal method that can be applied in the different phases of the site selectionprocess as well as for different sites, host rocks, and safety and disposal concepts for the development of scenarios.
Selected highlights with regard to FUNMIG's achievements include: For argillaceous host rocks, the systematic effort of investigating and comparing diffusion and sorption processes at different scales in different clay rocks with a variety of methods has substantially increased the knowledge basis for future safety cases.
The question of irreversibility of radionuclide sorption to colloids in crystalline fractures,(ii) a comprehensive model for cation and anion diffusion in clays for different scales and(iii) the applicability of mechanistic retardation models for strongly sorbing radionuclides in intact clay andcrystalline host rocks.
Geomechanical work completed to date has indicated that the host rocks are highly competent, allowing pit slope angles between 64 and 68 degrees, depending on local conditions, with crown pillars of 7 metres height being left between the base of the completed open pits and the subsequent underground mining operations.
These stationary models were used to test a range of scenarios, for example regarding thehydraulic properties of individual units or faults, and to analyse the impacts, for example, on the hydraulic gradients across the host rocks or the exfiltration zones.
The Company will commence academic studies andadditional fieldwork studies, including microscopic analysis of both mineralization and host rocks; trace elements and whole rock geochemistry; and radiogenic dating of magmatic rocks and mineralization, aimed at gaining a better understanding of the mineralizing processes within the district.
Both host rocks are practically identical in terms of release from the near-field but the Effingen Member is significantly behind the Opalinus Clay in terms of release from the confining units. The results documented in the main report for the safety-based comparison of the host rocks confirm the results of the analyses in the present report: The Opalinus Clay is the priority host rock in all three siting regions for L/ILW with two host rocks.
Optimisation is considered a key element in Stage 2 of the process: in order to make best possible use of the proposals from Stage 1,a three-stage optimisation is undertaken identifying the priority host rocks in the siting regions with more than one potential host rock, defining optimised disposal perimeters within the geological siting regions and placing siting regions with clear disadvantages into reserve; cf. steps 2, 3 and 5.
No drilling has tested this important host rock at Gabel.
The host rock in this trench is a pyrite bearing schistose rock. .
Overall, there is no preferred host rock to mineralization and alteration;
Sample 159059 represents the metasomatized ultramafic host rock next to spodumene-rich pegmatite.
Host rock temperatures remain below~90°C at all times.
There is no preferred host rock to mineralization and alteration;
Late in 2016 the Company recognized the potential for gold disseminated in the host rock adjacent to quartz veining at the Lone Star Zone see NR 1 November 2016.
Experts are even still arguing about the host rock we should choose and the type of matrix in which the waste should be sealed.
Deformable closure for tests on thermal expansion in potential host rock for a nuclear waste repository.
