Stylolite - Wikipedia
Stylolites (Greek: stylos, pillar; lithos, stone) are serrated surfaces within a rock mass at which mineral material has been removed by pressure dissolution, in a deformation process that decreases the total volume of rock.

缝合线 - 维基百科，自由的百科全书
缝合线 （英語： Stylolite）是 压溶作用 在岩體中所造成的鋸齒狀紋理。 压溶是將岩石中的一些礦物（通常是 方解石 或 石英）在高压应力区中被溶解，經过流体迁移，在低压应力区沉淀 [1]。 在這個變形過程中，岩石的總體積會減少。 其中若有不溶於水的礦物質，如 粘土 、 黃鐵礦 和氧化物，以及不溶性有機物 [2]，會呈現在缝合线上。 若岩石不含不溶性礦物，缝合线则不明顯 [3]。 均質岩石中最常見缝合线 [4]，例如 碳酸鹽 、 燧石 、 砂岩 中。 偶爾在某些 火成岩 和冰中可找到 …
Stylolite | Porosity, Sedimentary Rocks & Diagenesis | Britannica
Stylolite, secondary (chemical) sedimentary structure consisting of a series of relatively small, alternating, interlocked, toothlike columns of stone; it is common in limestone, marble, and similar rock. The individual columns never appear singly but occur as …
Stylolites: A Geologic Structure - ArcGIS StoryMaps
2019年11月18日 · Stylolites form as compressive features during pressure dissolution, where ions are dissolved and deposited in another location: this process is accelerated by high stresses (Fossen, 2016). As Merino (1992) explains, stylolites begin forming in areas of high porosity and stress, then finish forming in areas of low stress and porosity.
Stylolites: A review - ScienceDirect
2018年9月1日 · Stylolites are ubiquitous geo-patterns observed in rocks in the upper crust, from geological reservoirs in sedimentary rocks to deformation zones, in folds, faults, and shear zones. These rough surfaces play a major role in the dissolution of rocks around stressed contacts, the transport of dissolved material and the precipitation in ...
Stylolite - an overview | ScienceDirect Topics
Stylolites turn out to be most easily described in terms of their relationship to the fabric of the host rock, and two main types are described by Park in this manner: 1. Intergranular stylolites; in which case the amplitude of the seam is smaller than the grain size in the host rock, and. 2.
Stylolites are ubiquitous geo-patterns observed in rocks in the upper crust, from geological reservoirs in sedimentary rocks to deformation zones, in folds, faults, and shear zones.
Stylolites - SpringerLink
Stylolites are macroscopic serrate subplanar surfaces at which mineral material has been removed by pressure dissolution, resulting in a decrease in total volume of rock. Stylolites are made readily visible by the accumulation of residues of relatively insoluble minerals, such as pyrite, oxides, clays, and other silicates.
Stylolites in limestones: Barriers to fluid flow? | Geology ...
Stylolites—products of intergranular pressure-solution—are laterally extensive, planar features. They are a common strain localization feature in sedimentary rocks. Their potential impact on regional fluid flow has interested geoscientists for almost a century.
