Method and apparatus for determining a mineral component of a clay mineral, in particular swellable clay mineral in a rock

摘要

A method for determining a mineral component (sg) of a clay mineral, in particular of a swellable clay mineral, in a rock (o), wherein the– a transmission signal (s) in the infrared range, on the rock (o) and a light is radiated from the rock (o) reflected measuring signal (r) is detected,– Values of the measuring signal (r) in a wavelength range between a lower limit value (g1) and an upper limit value (g2) and which are determined quantitatively– from this the mineral content of the clay mineral is determined.
