“…즉, 자기미세구조 분석 결과에서는 단층 면에 거의 평행한 엽리구조가 발달된 것으로 나타나 는데, 이러한 특징은 실세 단층암에서의 미세구조 발 달 메커니즘이 순간변형에 기초한 미세구조 발달과는 차이가 있음을 의미한다. 단순전단에 의한 변형 매커 니즘을 논의하는 많은 연구 (Elliott, 1972;Lister, 1977;Skjernaa, 1980;Ramsay and Huber, 1983;Fossen, 2010) (Fig. 12).…”

“…Secondly, the symmetrical scatter of both D1 and D2 fold axes around the ENE directions in S1/S2 planes is consistent with extreme rotation of fold axes towards the transport directions with progressive non-coaxial shear (Fig. 1.4, Bell, 1978;, Skjernaa, 1980. Finally, some D1…”

“…1.4; Skjernaa, 1980). In addition, macroscopic-or mesoscopic-scale sheath folds are associated with bulk strains greater than 10 (Bell, 1978;Lister and Price, 1978;Skjernaa, 1989).…”

“…Bulk shear strain during D2 in the central, north, and east structural domains is interpreted to be moderate to high (a > 4-higher in the north domain), based on the tightly constrained distribution of D2 fold axes around the Le orientation ( Fig. 1.4, Skjernaa, 1980). …”

Tectonic implications of early silurian thrust imbrication of the northern exploits subzone, Central Newfoundland

“…Movement is assumed to have occurred parallel to a mineral rodding lineation developed in the fault rocks (Bryant and Reed, 1969) that plunges 45" southeast. The lineation is approximately parallel to hinge orientations of NW striking isoclinal folds from locality 1, suggesting that folds associated with this fault have been rotated into the movement direction along the fault plane, and that they are no longer parallel to their cut off lines (Skjema, 1979;Ramsay and Huber, 1987).…”
