This is aided by isotopic relationship and modeling with the geological history. Then surveyors should Visit the location and collect samples, looking for kimberlite fragments or indicator minerals. The latter have compositions that mirror the circumstances wherever diamonds sort, including Serious melt depletion or higher pressures in eclogites. On the other hand, indicator minerals is usually deceptive; an even better strategy is geothermobarometry, wherever the compositions of minerals are analyzed as should they were being in equilibrium with mantle minerals.[fourteen]
