Horse (geology) explained

A horse, in geology, is any block of rock completely separated from the surrounding rock either by mineral veins or fault planes. In mining, a horse is 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]
