Complicated assemblages of fine-grained low-temperature minerals challenge our understanding of mineralogy, both chemically and geologically. Crystal structures of minerals in complex geochemical environments should be related to the occurrences and distribution of the minerals. The discipline of Mineralogy has much to offer the Earth Sciences in this area: an understanding of the relationship between the paragenetic sequences of minerals and their corresponding crystal structures may be realized, and is crucial to understanding complex mineral occurrences. It is only very recently that the introduction of synchrotron radiation and CCD-based detectors to mineralogy has made it possible to solve the structures of crystals with effective volume < (20 ?m)3. Detailed knowledge of the structural relationships of fine-grained low-temperature minerals is now attainable, and will revolutionize understanding and applications of low-temperature mineralogy.
Much of my current research is focused on understanding
the occurrence, chemistry, and structural relationships of uranyl (U6+) minerals.
It is only recently that the extraordinarily complex nature of uranyl mineral
structures has become apparent, with the discoveries of topologies with repeats
in excess of 50 Å, and pentavalent uranium in mineral structures.
The structural complexity of uranyl minerals is a tremendous challenge to
our understanding of low-temperature mineralogy. More than 200 uranyl
minerals are known, and are the key to understanding the genesis of uranium
ore deposits. They are also of significant environmental concern: they
form due to the weathering of uranium mine and mill tailings, where soils
are contaminated with actinides, and are the main products of alteration
of spent nuclear fuel in a geological repository that is oxidizing and moist,
such as the proposed repository at Yucca Mountain. It is therefore
regrettable that the structures remain unknown for 2/3 of the 200 species.
As recently noted in the blue-ribbon peer review panel of the Total System
Performance Assessment of the Yucca Mountain project, the uranyl phases that
form under repository conditions will impact upon the release rates of the
radionuclides from the spent fuel because they may incorporate many of the
radionuclides into their structures. Much of my research is therefore
focused on the mechanisms and likelihood of incorporation of radionuclides
into the structures of uranyl minerals, as well as their ion-exchange properties.
