Secular Variation in the North American Kimberlite Formation: The Variable Connection to LLSVPs
Abstract Kimberlites are rare and perplexing igneous rocks that may represent the deepest‐sourced melt type extracted from within the Earth's mantle, and their origin may be associated with Large Low Shear Velocity Provinces (LLSVPs) along the core‐mantle boundary.

Material aspects of kimberlite rocks productivity
Most of investigated kimberlite diatremes of the Siberian platform represent multiphase pipes. Each magmatic phase of intrusion, formed inside diatremes, is composed by kimberlites with specific petrographic and petrochemical type possessing a number of ...

The central issues in petrology have remained remarkably unchanged in the last 50 years. In igneous petrology, the focus is on understanding the nature and cause of diversity in igneous rocks: on identifying primary magma types and constraints on the ...

Correlative Tomography for Polymineralic Inclusion Composition in Sublithospheric Diamonds
Abstract Sublithospheric diamonds and their inclusions are the deepest known samples from the Earth's mantle. Typically, the inclusions are trapped as minerals which are only stable in the deep mantle, retrogressing into multiple phases during their uplift. Determining the bulk inclusion composition is difficult but crucially important.

Deformation Controlled Fluid Mass‐Transfer Processes in Ancient Orogens
Abstract Despite abundant empirical evidence, the details of coupled deformation and mass transfer processes within a framework of the crustal architecture of ancient orogens remains enigmatic. Geophysical imaging of the Larder Lake‐Cadillac deformation zone, a well‐endowed crustal‐scale fault system in the Superior Province of the Canadian Shield ...

ABOUT LITHOMINERALOGICAL COMPOSITION OF ANCIENT SEDIMENTARY DIAMONDIFEROUS ROCKS
Litho-mineralogical and structural-formation generation features of Upper Devonian-Carboniferous crusts of weathering on terrigenous-carbonate rocks, kimberlites and deposits enriched by products of their redeposition, have been studied, that allowed ...

The Kaapvaal craton seismic anisotropy: Petrophysical analyses of upper mantle kimberlite nodules
International audienceA dense network of seismic stations has been deployed on the Kaapvaal craton (South Africa) to investigate the upper mantle seismic structures. In order to bring independent petrophysical constraints, we analyze a direct sampling of
