沉积物或火山岩物质的压实速率需要重建床的原始厚度，这反过来又需要重建沉降速率，海平面上升，或者在火山岩的情况下，喷发地点的位置或方向。压实率的知识也可以帮助重建变形化石。变形化石的已知形状可以确定它们所经历的压实作用。本文报道了内蒙古乌达早二叠世火山凝灰岩的压实速率，它是由已知解剖学的直立树蕨茎的变形确定的。在这种情况下，压实率为0.56，表明原始厚度的44%仍然存在。
Compaction rates of sediments or volcaniclastic material are needed to reconstruct original thickness of a bed, which in turn is required to reconstruct subsidence rates, sea‐level rise, or in the case of volcaniclastic, the location or direction of the eruption site. The knowledge of compaction rates can also aid in the reconstruction of deformed fossils. The known shape of deformed fossils can allow the determination of the compaction they experienced. Here we report the compaction rate in an early Permian volcanic tuff from Wuda, Inner Mongolia, determined from the deformation of standing tree fern stems of known anatomy. The compaction rate has been found to be 0.56 in this case, indicating that 44% of original thickness remains.
