In this paper 1:10 000 high-precision magnetic survey work has been done using GSM-19T proton magnetometer in Halaganlawusu area. There were data processing including gridding, filtering, reduction to the pole, continuation, derivation, and so on. By precise interpretation and inference with magnetic anomaly, the distribution characteristics of basic rock mass was found out. According to the magnetic survey data and geological research, fitting-inversion of measured magnetic section P1, P2 were done. It preliminarily concluded the distribution characteristics of underground ore rock mass and achieved the effect of the geophysical prospecting.

On the basis of presenting the piping and seepage detection by magnetic-electric prospecting method, the authors analyzed and testified validity of the method. According to calculated results, the magnitude of magnetic field of artificial current was smaller on section if electrodes and cables were set rationally. Usually, the magnetic field magnitude of piping had several times to more than decuple comparing with magnetic field of artificial current. So, the magnetic abnormity could be detected easily by high-precision magnetometers. At the same time, their curves’ characteristics were different evidently. The analysis result shows that the piping and seepage of dyke can be detected by combining method of direct current supplying and high-precision magnetic survey.

The paper presents the results of high-precision magnetic surveys by a quantum magnetometer using an unmanned aerial vehicle (UAV). The object of research was an area of 10 hectares (500 × 200 m) at the archaeological site of New Kurya in Western Siberia. The accuracy of the registration of the induction module of the geomagnetic field was not lower than 0.3 nT. The spatial accuracy of GPS coordinates lies in the submeter range. Magnetic anomalies caused by ancient mounds with an amplitude of up to 5–10 nT were revealed. The technique for isolating such low-amplitude anomalies included taking into account the geomagnetic variations of the external field, the regional anomalous field, and the use of a number of algorithms for the statistical processing of primary data. Identified magnetic anomalies can reliably determine the features of the device and the size of the mounds, including those not expressed in relief. The information received makes it possible to plan a strategy for archaeological study of this monument at a qualitatively different level. The prospects of further development and use of the technology in question for solving archaeological problems are noted.

Conventional SAD patterns as obtained in the TEM present difficulties for identification of materials such as asbestiform minerals, although diffraction data is considered to be an important method for making this purpose. The preferred orientation of the fibers and the spotty patterns that are obtained do not readily lend themselves to measurement of the integrated intensity values for each d-spacing, and even the d-spacings may be hard to determine precisely because the true center location for the broken rings requires estimation. We have implemented an automatic method for diffraction pattern measurement to overcome these problems. It automatically locates the center of patterns with high precision, measures the radius of each ring of spots in the pattern, and integrates the density of spots in that ring. The resulting spectrum of intensity vs. radius is then used just as a conventional X-ray diffractometer scan would be, to locate peaks and produce a list of d,I values suitable for search/match comparison to known or expected phases.
