  1. Interbedding (Petrology 💎)

    In geology, interbedding occurs when beds of a particular lithology lie between or alternate with beds of a different lithology. For example, sedimentary rocks may be interbedded if there were sea level variations in their sedimentary depositional environment. Intercalation is a special case of interbedding where a layer is variably inserted into an already existing s...

  2. Lens (geology) (Petrology 💎)

    In geology, a lens or lentil is a body of ore or rock that is thick in the middle and thin at the edges, resembling a convex lens in cross-section. To thin out in all directions is to "lens out", also known as "lensing". The adjectives "lenticular" and "lentiform" are used to describe lens-like formations. Lenticle is a synonym for lentil, but may also refer to a fragment of rock that...

    [For almost 300 years – from 1709 to 2004 – Penicuik and district was producing high-quality paper which went out all over the world; Walter Scott’s Waverley novels and Robert Louis Stevenson’s notebooks were printed on Penicuik paper, and Turner painted on it too.]

  4. Unravelling The Dance Of Earthquakes - Evidence Of Partial Synchronization Of The Northern San Andreas Fault And Cascadia Megathrust

    “Previous paleoseismic work has suggested a possible stress triggering relationship between the Cascadia subduction zone and the northern San Andreas fault based on similar event timings. Turbidite successions correlated to both systems may support this hypothesis. Historic earthquakes in 1980 and 1992 in the Cascadia subduction zone and the 1906 earthquake on the northern San Andreas fault left turbidite records that are temporally well constrained by bomb-carbon−supported age-depth models..."
