| 摘 要： | 利用不同类型鱼嘴状石香肠构造恢复能干层原岩的初始厚度，并进一步分析原岩发生在应变椭球Z轴方向和X方向
的线应变，以应变差折射流变计的方法为基础，推导出一种求相同基质中相邻能干层粘度比的估测方法。以湖北大冶铁山
地区采集的两块鱼嘴状石香肠标本为例进行了应用尝试，得到大理岩基质中两层不同的角岩鱼嘴状香肠体的粘度比分别为
3.07和0.75。

| Abstract: | The initial thicknesses of the original rock layers can be restored by various fish head boudins. Furthermore, we
can analyze the linear strain in Z and X axes of the strain ellipsoid of the original rocks by the layer thicknesses. In this article,
a method for estimating the viscosity ratios of adjacent competent layers was derived from the Strain Differential Refraction
Rheology Gauges. An application trial was made for two specimens of fish head boudins from the Tieshan area, Daye, Hubei
province. We obtained the viscosity ratios of two adjacent fish head boudin hornfels layers in marble matrix, which are 3.07 and
0.75, respectively. |
