### **Table 2.**

*Average composition of Mg-imenite in pipes of the Daldynsky field.*

*Sketch map showing the location of kimberlite pipes in the Daldyn field. The names of the pipes are given in Table 2 (the numbers for pipes on the map and in the table are the same). The clusters of pipes are shown on the map as solid ovals, which group together pipes containing Ilm of similar composition.*

While the first type of distribution is dominant for Ilm from the southern part of the Daldyn field, the third type is essentially characteristic of pipes from the northern part of the field.
