Horse is the geological technical term used for any block of rock completely separated from the surrounding rock either by mineral veins or fault planes. In mining the term refers to a block of country rock entirely encased within a mineral lode.[1] In structural geology the term was first used to describe the thrust-bounded imbricates found within a thrust duplex.[2] In later literature it has become a general term for any block entirely bounded by faults, whether the overall deformation type is contractional, extensional or strike-slip in nature.[3][4]
