Ultrathin sections are stained immediately after cutting by placing them in contact with staining solution and then placed on a slide covered by a celloidin film. This method largely avoids precipitates of heavy metals. The recovering of celloidin film is improved using a stainless steel basket. This technique is far more reliable than that involving use of a filter paper.

Imaging logging is a new technique which has been developing in recent years, its’ silo facilities could collect large information with high resolution, and the measurement result is usually presented in graphics after processed. This paper presents a new imaging logging technique based on magnetic-acoustic Tomography with Magnetic Induction(MAT-MI), introduces its’ logging principle, gives detailed experimental system, makes a simple copper coil experiment and verifies the feasibility of the technique. These studies will lay a foundation for practical application of new imaging logging technology.

AbstractThe results of a new technique for the measurement of the thickness distribution of fundamental particles are reported. The technique is based on high-resolution transmission electron microscopy (HRTEM) of Na-saturated mixed-layer illite-smectite dispersed in polyvinylpyrrolidone (PVP-10). Intercalation of PVP-10 increases the spacing of expandable interlayers and changes the arrangement of particles so that the number of layers per fundamental particle can be counted easily on HRTEM images. The data obtained by HRTEM on PVP-10-intercalated illite-smectite of hydrothermal origin are compared with data from the Pt-shadowing technique. A good agreement between the two methods for the measured thickness distributions, mean thickness and expandability confirms the reliability of the new technique. The same technique is applied to a set of four sedimentary samples with different expandabilities (83-18%). The thickness of illite particles from shales and claystones has a lognormal distribution. Detrital anddiscrete illite particles can be distinguished from the thickness distribution of authigenic illite.
