Boudinage

Boudins of marble (white) in lime silicate Hornfels

Amphibolite facial boudin in the Rhodope Mountains (southern Bulgaria)

Boudinage (after French boudin for blood sausage ) describes a certain type of rock structure in geology . This structure is created by pulling banked rocks , whereby banks disintegrate into separate individual structural units (so-called boudins ), for which a rounded, ellipsoidal shape is typical, and which are finally completely surrounded by the previously adjacent rock. Often one can find minerals deposited between individual boudins (e.g. calcite or quartz ).
