Syngenetic rapid growth of ellipsoidal silica concretions with bitumen cores
Abstract Isolated silica concretions in calcareous sediments have unique shapes and distinct sharp boundaries and are considered to form by diagenesis of biogenic siliceous grains. However, the details and rates of syngenetic formation of these spherical concretions are still not fully clear. Here w...
