The results are obviously quite acceptable for many purposes. It must be pointed out in this connection that an accurate quantitative mineralogical analysis of a soil clay is a very laborious procedure involving much experimental and interpretative work consequently, one has to assess the accuracy required before embarking on any investigation. Whatever is eventually decided, however, it is clear that thermal methods have their place in any such investigation. 

Quantitative chemical analysis using the characteristic x-rays emitted by the specimen in the electron microscope is considered in Chapter 7. Since the basic principles are the same as for the electron microprobe (which will be familiar to most geologists and mineralogists), emphasis is placed on those aspects of the technique that are related to the use of thin foil specimens. The intensities of the characteristic x-ray peaks depend on the crystallographic orientation of the specimen with respect to the electron beam this effect is the basis of the relatively new technique ALCHEMl (atom location by channeling enhanced microanalysis), which under certain conditions can be used to determine the location of minor element atoms in a crystal structure. This technique is potentially very useful for mineralogical studies and is therefore discussed in some detail. 

Samples for clay mineralogical analysis were prepared using standard gravitational-technique. Semi-quantitative estimates of the relative abundance of clay minerals in the <2 pm fraction were made using the method given by Moore Reynolds (1989).

The evolution of hydration and carbonation of powder samples was assessed by XRD, mercury intrusion porosimetry (MIP), FTIR, DTA/TG, EDXRF and SEM. By identifying calcium silicate hydrates (CSH) and calcium aluminate hydrates (CAH) at different ages, not only qualitatively, but also semi-quantitatively, the hydration and carbonation processes could be monitored. The mineralogical analysis was investigated by XRD with a Siemens D-500 diffractometer (40 kV/35 mA) the spectra were collected...

The technique of DDIF provides a quantitative characterization of the complex pore space of the rocks to supplement conventional mineralogy, chemistry and petrology analyses. A combination of DDIF, Hg intrusion, NMR T2 and image analysis has become the new paradigm to characterize porous rocks for petroleum applications [62, 61]. 

In addition to Klaproth s pioneering work in quantitative analysis, he made a major contribution to mineralogical chemistry and discovered many elements in the process. His efforts did not go unrewarded, since he became Berlin s first Professor of Chemistry.
