Title :変形前のマーカー楕円の性質 ―沖縄島国頭層群嘉陽層の場合―

Abstract :The method that estimates the initial marker ellipse and the averaged initial ellipse is described. Finite strain analysis carried out previously on the Kayo Formation, Kunchan Group, Okinawa-jima (Hayashi, 1988, 1989) is again examined. It is considered that most of the quartz grain markers do not have initial fabrics from the observation of the distribution tendency of long axes of initial marker ellipses. This is also confirmed by the examination with Lisle's symmetric index test and θcurve test (Lisle, 1977, 1985). The strain analysis was performed precisely because the axial ratios of the average initial ellipse are close to 1.O.
