为了研究硅屑岩的物性分类并设计可描述这类岩石物性参数之间关系的新模式,对于碎屑沉积层序中存在的各类岩石进行了大量的、高有效压力下的物性测量,建立了内容广泛的数据库。在光学显微镜、扫描电镜(SEM)和实验数据的基础上,划分了四个重要的物性组:(1)纯净的砂屑岩;(2)蚀变的砂屑岩和长石砂岩;(3)瓦克岩;(4)砂质页岩。每个物性组都由不同的矿物组成、结构和粘土的构造位置来表征。第二组中的粘土矿物主要是不稳定硅酸盐矿物和岩屑的成岩分解产物,由此导致了这些颗粒支撑的岩石的弹性模量的急剧变小。另外页岩为基质支撑的岩性,在较低程度上瓦克岩也是如此,这就是在类似的孔隙度下它们的弹性模量低于前两组岩石的原因。据发现,每组岩石都有线性的纵波速度—孔隙度关系,且有很高的相关系数。与时间平均方程和线性回归法相比,这种方法可根据声波测井曲线得出相当准确的孔隙度估算或岩性预测,因为前两者都没有考虑岩石的矿物和结构因素。此外还发现,体现各物性组线性趋势特征的孔隙度—速度曲线,主要反映了成岩作用的过程。砂岩和页岩的初始岩化(固结作用),基本上表现为小规模的局部接触粘结,因为在颗粒界面发生了化学作用,因而具有切变模量急剧增大的特征。虽然这一成岩阶段的孔隙度缩减十分有限,但速度有明显增加。进一步的成岩作用表现为较为平缓的线性趋势,反映了相当可观的孔隙度缩减,其原因在于在温度作用下,颗粒支撑的岩石发生了溶解—沉淀,而基质支撑的岩石发生了粘土的相转化。

有效应力σ_(ij)的精确表达式,特别是导致有孔隙流体材料的弹性应变的应力P(有效应力)是基于假设之上的,仅对Hook定律有效,即σ_(ij)=σ_(ij)-αPδ_(ij)和P=P_c-P_p,这里α=1-(K/K_s),P_c和P_p是围压和孔隙压力,K和K_s分别是干燥岩石(... 详细信息

有效应力σ_(ij)的精确表达式,特别是导致有孔隙流体材料的弹性应变的应力P(有效应力)是基于假设之上的,仅对Hook定律有效,即σ_(ij)=σ_(ij)-αPδ_(ij)和P=P_c-P_p,这里α=1-(K/K_s),P_c和P_p是围压和孔隙压力,K和K_s分别是干燥岩石(排水状态下)和岩石基质(岩石固体部分)的体积模量。Geertsma(1957年)和Skempton(1960年)在实验的基础上首次提出关于P的方程。该表达式虽然不直接依赖于孔隙度,但是当有效应力P等于围压时孔隙消失,因此K=Ks。如果使用σ_(ij)方程中的有效应力定理,那么可根据没有孔隙压力的固体弹性模量确定一个具有孔隙压力的多孔固体的应变。有效应力表达式非常准确地描述了砂岩和花岗岩样品在围压和孔隙压力达到2.5kb(250MPa)时的应变。结果表明,该有效应力定理不适用于非弹性过程(如断裂)。

世界上一些大山脉的构造复杂性似乎是主要板块碰撞的结果,而另一些山脉则是许多监列裂块形成的,通常称为"外来地体",它们的源地很远,例如北美西部的大山脉,均由这种外来地体组成的。现在许多类似的外来体可以是高原,它们约占现在海底的10%。这些高原镶嵌于海洋板块并随其迁移,最终要增生于大陆俯冲带之中。这种增生作用涉及这些问题:包括边缘活动带的火山空区,不规则的地震活动类型、蛇绿岩的侵位、造山变形,大陆通过这种过程增长以及边缘盆地的圈闭。
