EXPERIENCE OF USING ELECTRICAL TOMOGRAPHY, RADON SURVEY AND MICROSEISMIC SOUNDING IN SEARCH FOR PIPES CONTROLLED BY FAULT ZONES

Геодинамика и тектонофизика, 2020
The complex of geophysical methods was successfully applied in the Alakit-Markha kimberlite field of the Yakutsk diamondiferous province. A pipe was identified in the local forecast area specified within the field at the previous stage of prospecting ...

The Deep Structure of the Kimberlite Pipe Volchya in the Arkhangelsk Diamond Province and Controlling Faults Based on Passive Seismic and Radiological Methods (Northwest Russia)

Applied Sciences
The successful prospecting of kimberlite pipes is dependent upon a comprehensive understanding of the deep structures of the pipes and the host geological formation. This is a challenging task, given the complex nature of diamond deposits, the small size

Comparative Study of the Kimberlites of Bakwanga (North Group) and Bakwa-Kalonji (South Group) In East Kasai, Democratic Republic of Congo.

Analecta
The presence of kimberlites in the Democratic Republic of Congo has been known since buttgenbach reported a typical ‘yellow ground’ in Katanga as early as 1908, and prospecting work before and after 1914 had already identified twenty-four pipes in ...

Use of gamma-ray spectrometry for identifying weakly magnetic diamondiferous kimberlites [PDF]

, 2016
Diamondiferous kimberlites are the most important source of bedrock diamond deposits. The goal of the study is to analyze the use of gamma-ray spectrometry techniques to explore weakly magnetic diamondiferous kimberlites.

Styles of Alteration of Ti Oxides of the Kimberlite Groundmass: Implications on the Petrogenesis and Classification of Kimberlites and Similar Rocks [PDF]

, 2018
The sequence of replacement in groundmass perovskite and spinel from SK-1 and SK-2 kimberlites (Eastern Dharwar craton, India) has been established. Two types of perovskite occur in the studied Indian kimberlites.

Brines in deep horizons of the Udachnaya kimberlite pipe

Geodynamics & Tectonophysics, 2018
The study was focused on groundwaters sampled from boreholes drilled to deep horizons of the Udachnaya kimberlite pipe and the host sedimentary strata. Brines in the rocks significantly complicate underground mining. Analysis of the hydrogeological setting is required to ensure safety during mining to the design levels.

MANTLE TERRANES OF THE SIBERIAN CRATON: THEIR INTERACTION WITH PLUME MELTS BASED ON THERMOBAROMETRY AND GEOCHEMISTRY OF MANTLE XENOCRYSTS

Геодинамика и тектонофизика, 2019
We have studied variations in the structure and composition of minerals from the pipes of the Yakutian kimberlite province (YKP) in different mantle terranes of the Siberian craton.

Hetero-ore-bearing regional permeable zones in the plate complex of the East Siberian platform

Руды и металлы
The article considers hetero-ore-bearing regional permeable zones identified by the author in rocks of the plate complex of the East Siberian Platform. A geological and genetic model of these ore-bearing zones is proposed.
