• 論文の詳細を見る

• The gold decoration technique of electron microscopy was applied to natural (001) surfaces of two kinds of pyrophyllite crystals (green and white colored specimens) collected from "Roseki"deposits distributed in the Shokozan area, Chugoku province, southwest Japan. The specimens are characterized by some parallel steps of malformed circular or polygonal forms with varying step separations. Crystals exhibit paired and single steps which may be correlated to 2M or 1T polytypes, respectively. The paired steps take place normally by the interlacing process on their crystal growth. The different surface microtopographs on both green and white colored crystals are explained based on the understanding on spiral morphology.
