ABSTRACT:
This invention relates to a method for preparing thin sections for the microscopic study of small fragments of rock, dust, microfossils or miscellaneous debris, agglomerated into pellets of special characteristics. The method according to the invention comprises the use of a plate of plastic material containing a series of cells which are filled with an agglomerate consisting of rock fragments surrounded with epoxy resin. Said plate is then heated in an oven to a temperature not exceeding 75.degree. C. for some hours in order to accelerate the hardening of the resin and to obtain said pellets.
