   Flint is a sedimentary rock made over 100 million years ago at the same time as the chalk bedrock. Small sea animals such as sponges use silica (a kind of sand) from the sea water to form their skeletons, much in the way humans use calcium to build our bones.

   Sep 15, 2023 · Flint, sometimes interchangeably referred to as chert, is a type of cryptocrystalline or microcrystalline quartz that typically forms in sedimentary rocks. It is known for its conchoidal fracture, which means it breaks with smooth, curved surfaces, creating sharp edges.

   Jul 17, 2020 · In the modern era flint remains a material of concern in engineering causing damage to core-drilling operations, tunnelling machines (Fig. 8) and cable trenching machines onshore and offshore northwest Europe. Flint also impacts the ease with which piles can be driven into chalk.

   What fossils are found in Flint?

   • All fossils in the pure white chalks have been found preserved in flint, including very small meso-fossils such as crinoids, bryozoans, bivalves and brachiopods, and very large ammonites (Parapusozia sp.) found in the Early Campanian Newhaven Chalk on the Sussex coast.

   Where is flint found?

   • Flint is found in areas with chalk bedrock, this is because flint formed within the sediment that later became chalk. At this point it's worth noting that the chalk was formed in much larger quantities from the remains of microscopic calcareous plankton, particularly Coccolithophoroid algae, whose tiny skeletons are known as coccospheres.

   Do flint nodules contain fossils?

   • A wide range of fossils can be found within flint nodules, indeed in many instances the nodule itself is in fact an internal mould of a sea creature. The silica accreted around the nuclei of organic remains and biogenic structures, such as the remains of sponges or the burrows of crustaceans.

   Are flints a clue to sedimentary processes?

   • Whichever model for flint formation is accepted, flints provide vital clues to sedimentary processes on the Chalk sea floor picking out erosional channels and channel-fills (Fig. 24) as well as slump folds and tectonic structures (Mortimore, 2011, 2014, 2019). Fig. 24.
