TECTONIC FEATURES OF KIMBERLITE BODIES LOCATION AND THEIR USE IN FORECASTING (EXEMPLIFIED BY KIMBERLITE FIELDS OF THE WESTERN YAKUTIA)
It is recommended that large-scale diamond deposit forecasting in the Western Yakutia should take into account structural-tectonic models of kimberlite body bunches proposed as tectonic criteria. Analysis of ore bunch structure in productive kimberlite fields showed that each studied target has a specific tectonic image - universal signs are rare though bunches of one kimberlite field (diamondiferous area) have certain similar features. Some kimberlite bodies also have individual features which are less significant for one kimberlite field and more essential for different fields. Due to this, field-specific models are recommended to be used in forecasting for each ore field (diamondiferous area).The identified tectonic regularities of kimberlite bunch structure were used in a forecast estimate of an expected buried kimberlite field.
