Application of Tagged Neutron Method for Detecting Diamonds in Kimberlite
Instruments, 2020 The results of testing a prototype of a separator for detecting diamonds in kimberlite ore using tagged neutron method are discussed. Kimberlite ore was irradiated with fast tagged neutrons with an energy of 14.1 MeV.

Comparative characteristics of diamonds from areas with a high density of kimberlite bodies
Известия высших учебных заведений: Геология и разведка, 2023 Background. This paper presents a comparative study into diamonds from kimberlite bodies of the Verkhnemunsky field (Zapolyarnaya, Novinka, Komsomolskaya-Magnitnaya and Poiskovaya), the results of which allow these minerals to be distinguished from those

Diamonds from low-grade kimberlite
Руды и металлы, 2022 Based on exploration and sampling work on the Siberian platform (SP) the uneven diamond content of various diatremes was established. During the exploration apart from the pipes with high or medium content of a useful component also the diatremes with ...

Kimberlite ascent and eruption [PDF]
Nature, 2007 Wilson and Head model kimberlite ascent and eruption by considering the propagation of a volatile-rich dyke. Wilson and Head's model has features in common with Sparks et al., but it is inconsistent with geological observations and constraints on volatile solubility. Here we show that this may be due to erroneous physical assumptions.

Attrition in the kimberlite system [PDF]
Mineralogy and Petrology, 2018 The sustained transportation of particles in a suspension commonly results in particle attrition leading to grain size reduction and shape modification. Particle attrition is a well-studied phenomenon that has mainly focussed on sediments produced in aeolian or fluvial environments. Here, we present analogue experiments designed to explore processes of

Review of the spatial distribution of kimberlite pipes in the tectonic structures of the world
Geo&BioKimberlite pipes are vertical or inclined cylindrical or cone-shaped bodies filled with kimberlite, an ultramafic igneous rock. The diameter of kimberlite pipes can vary from a few metres to 1.5 km, and their depth reaches several kilometres.
