Beekite

Base of the scleractinian coral Microsolena showing beekite rings; Middle Jurassic of southern Israel.

Beekite is a distinctive form of chalcedony usually associated with silica replacing carbonate minerals in fossils (e.g. the top part of the coral illustrated).

Beekite, recognised as small, concentric rings (cylinders, ellipsoids, or spheres in 3D) of microcrystalline quartz is recorded as first brought to attention of geologists by Henry Beeke, probably from studies around Torbay. Early studies were reported by Thomas McKenny Hughes, in Devon, and R. Etheridge in Australia.
