methods: processing

The processing of polyester crystic resin impregnated soil samples into soil thin section slides is effectively a 5 stage process, bonding to a slide, cutting off excess, grinding to desired thickness, polishing and finally coverslipping. Bonding soil block to slide… Continue Reading →

methods: impregnation

The choice of resin for impregnation is mainly governed by the the intended use of the thin section slide. In the case of soil thin section production the most widely used resin is polyester (Polylite 32032-00). This resin has a… Continue Reading →

methods: drying

When using either epoxy or polyester resins in the production of soil thin sections it is essential to remove as much water from the soil to allow the hydrophobic resin to fill all the pore spaces effectively. This can be… Continue Reading →

methods: sampling

The main aim of sampling is to obtain soil samples in as undisturbed a state as possible. The process involves the careful use of Kubiena tins inserted into soil profiles, removed, sealed and bagged for transport to the lab. back… Continue Reading →
