Recent Research Projects

Development and applications of high precision U-Pb geochronology for Earth and planetary sciences

2016/17-2019/20 • $240,000 • PI
This proposal is for funding one post-doctoral fellow (PDF) and one graduate student to carry out research on improved techniques of U-Pb geochronology and its applications to understanding the development of terrestrial crust and the early solar system. Research will focus on several areas. The...

Development and applications of high precision U-Pb geochronology for earth and planetary sciences

2011/12-2015/16 • $205,000 • PI
The focus of this research is the application of high precision uranium-lead (U-Pb) geochronology to better understand Earth history and the early development of the solar system. The U-Pb system is the most powerful geochronometer partly because determination of precise ages in Precambrian...

analytical electron microscope (asem) for research and training in textural and chemical analysis

2010/11 • $143,000 • PI,CO
Detailed chemical and textural analysis of synthetic and natural samples is central to the development of advanced engineered materials as well as to our understanding of the Earth and terrestrial planets. The electron microscope is one of a family of modern instruments used to provide this...

Electric pulse disaggregator and hydroseparator for micromineral research

2010/11 • $136,165 • PI,CO
Revolutionary insights into the origins of the solar system and Earth's continents, oceans and early life forms is being gained from measuring the time and environmental information preserved in very small, almost dust-sized, mineral crystals in rocks and meteorites. Key to new and future...

High sensitivity S-option upgrade for an inductively coupled plasma mass spectrometer system

2010/11 • $24,500 • PI,CO
The inductively coupled plasma (ICP) source with a quadrupole mass filter is the most cost effective instrument for measuring isotopes with moderate precision and high throughput. Combined with a laser ablation source, this is used for dating large numbers of zircon grains to moderate precision....
