Heat Generation in Cratonic Mantle Roots—New Trace Element Constraints From Mantle Xenoliths and Implications for Cratonic Geotherms
Autor: T. McIntyre, K. Kublik, C. Currie, D. G. Pearson
Publikováno v: Geochemistry, Geophysics, Geosystems, Vol 22, Iss 9, Pp n/a-n/a (2021)
Abstract Heat generation within the cratonic lithospheric mantle (CLM) is an important but poorly determined parameter for constructing cratonic geotherms. Direct measurement of heat producing element (HPE: K, U, and Th) concentrations in bulk‐rock

Chemical studies of kimberlite indicator minerals from stream sediment and till samples in the southern Mackenzie region (NTS 85B, C, F, G), Northwest Territories, Canada
Autor: RC Paulen, D G Pearson, I R Smith, S J A Day
Till (n=196) and stream sediment (n=60) samples were collected in the area south and west of Great Slave Lake, Northwest Territories (NTS 85B, C, F, and G), over the course of 3 summer field seasons. Samples were processed to recover kimberlite and o

Trace-element signatures of kyanite-eclogites from a southern Indian kimberlite
Autor: Kula C. Misra, D. G. Pearson, A. Ishikawa, D. K. Paul, Mahesh Anand
Publikováno v: The Open University (ORO-Open Research Online)
Eclogite xenoliths found in kimberlites provide important information about geodynamic processes that were involved in the cratonic evolution of a region. Most eclogite xenoliths are demonstrably Precambrian in age and have equilibrated over a range

The examination of disperse crystalline phases in polyvinyl chloride
Autor: E. W. J. Michell, D. G. Pearson
Publikováno v: Journal of Applied Chemistry. 17:171-177
The examination by microscopy and X-ray diffraction, of fine crystalline powders embedded in polyvinyl chloride is described. These techniques are applied to an investigation of the stabilising reaction of white lead during thermal degradation of PVC

The development of lithospheric keels beneath the earliest continents: time constraints using PGE and Re-Os isotope systematics
Autor: Richard W. Carlson, Dmitri A. Ionov, Maya G. Kopylova, D. G. Pearson, G. J. Irvine
Publikováno v: Geological Society, London, Special Publications. 199:65-90
Continued studies of xenolith suites found in kimberlites on and around the Kaapvaal Craton, together with those from newly discovered localities on other cratons, are providing new insights into the generation and evolution of the Earth's oldest con
