Mountain development has an influence on long-term changes of uplift, erosion, and groundwater flow related to change in hydraulic gradient. Provenance analysis is one of promising geological methods to understand origin and formation process of mountains. Case study in the Tono area, central Japan has been done for research and development of individual technique to estimate a provenance. In this report, petrological descriptions by meso- and microscopic observations and elemental distributions using scanning X-ray analytical microscope of basement rocks (silicic igneous rocks) from the study area were compiled.

Times Cited Count：7 Percentile：30.7(Physics, Applied)A grazing incidence reflection-type soft X-ay microscope, using a Fresnel zone plate and a soft X-ray laser with wavelength 13.9 nm and pulse width 7 ps, was developed. Submicron size groove structures made on a Pt film were clearly captured at a single shot exposure, with spatial resolution of about 360 nm. A wide field view of 100 
m square was secured under the Kohler illumination. This microscope also had a large depth of focus of more than 100 m and was proven to have a sufficient performance for observing surface morphological changes.

The neutron zooming tube has been developed using electronic zooming TV readout system for an X-ray microscope. This system consists of the photocathode, the electro-magnetic coil assembly and the CCD TV camera etc.. The photocathode consists of transmission type CsI layer in combination with neutron converters such as Gd foil. The system position sensitive resolution of 20m has been obtained using neutron converter. We have found that it is determined from the distance between the CsI layer and the neutron converter, then the limiting resolution could be improved.

Times Cited Count：11 Percentile：42.73(Physics, Applied)A scanning-type synchrotron radiation Mossbauer microscope was designed and installed at the nuclear resonance beamline BL11XU of the SPring-8 facility. The focused Mossbauer probe beam (
20m) is obtained by the combination of a high-resolution monochromator, a multilayer X-ray focusing mirror and a pinhole slit. Using this Mossbauer microscope, we have performed, for the first time,the synchrotron radiation Mossbauer microscopic measurements of nuclear resonant forward scattering from an iron borate single crystal as a function of the sample position. It was found that the observed Mossbauer time spectra depend on the direction of the local hyper fine magnetic field and the local specimen thickness.
