説明
We invented a completely new simple method and new equipment necessary for high-resolution active fault studies. Vertical thin sections of unconsolidated soil layers are extracted by a newly invented sampler named “Geo-slicer”.<BR>Extracted sections can be taken to a laboratory for close examination or can be displayed at a meeting or even stored for future re-examinations (Fig. 1). This method enables us to carry on high-resolution analyses not only in active fault studies but also in other fields of Quaternary sciences with less expenditure of time, labor and money.<BR>We made three different-sized Geo-slicers and tested them successfully in the field. A Geo-slicer is made of steel and has a simple structure composed of a box and its shutter (Figs. 2 and 3). Several devices are implemented to the box and the shutter, such as wedge-shaped side walls and a stopper at the bottom of the box for easy pull-out of the equipment and steady-holding of samples (Fig. 4).<BR>For sampling, we firstly intrude the box vertically down into the ground by using a vibro-hammer (Photo 1) and then shutter sliding along the thin slits attached to the both sides of the box, and pull out the equipment containing samples.<BR>The extracted layers of sediments are surprisingly undisturbed and show almost the same features as previously observed on trench walls excavated close to the extraction sites (Photos 2 and 3). The largest sample collected by this method is 150 cm wide, 270 cm long (deep) and 8-15 cm thick (Photo 4).<BR>This sampling method is far more effective on active fault studies than the conventional trench excavation technique and we will be able to carry out three-dimensional analysis of active faulting, restoration of horizontal fault slips and so on for paleoseismological studies (Fig. 6).
