Preliminary pedogeochemical and biogeochemical studies on the Hinota kimberlite,Panna District,MP

Distribution of a number of trace elements in the Hinota kimberlite pipe, its overlying soil and selected vegetation is discussed in relation to the distribution of the same elements in the soils and vegetation overlying the quartzite country rock through which it is emplaced. The values of most elements in Hinota are similar to those of kimberlites from some other parts of the world, but Ni and Cu are higher. These elements in a “floating reef” of the Dhandraul Quartzite in the pipe closely follow the averages for other sandstones. It is observed that most elements in the soil over the kimberlite are significantly higher than in the soil over the surrounding country rock, particularly Ni, V, Cu and Cr. These could serve as reasonable guides to prospecting for kimberlites. Trace elements in the ash of selected trees growing over the diatreme and the country rock do not show any significant differences.
