Abstract:
1. A clinocompass for measuring a strike and a dip on an irregular geological outcrop, the clinocompass comprising: a base plate; first and second compasses provided at both side portions of a top surface of the base plate in opposition to each other such that each of the first and second compasses is rotatable outwardly; a first auxiliary compass provided on a top surface of the first compass and rotatable inwardly; and a second auxiliary compass provided on a top surface of the second compass and rotatable inwardly, wherein the first and second compasses are elastically installed on the base plate through a coupling with first spring hinges, respectively, such that the first and second compasses have elasticity to return to initial mounting positions of the first and second compasses, and the first and second auxiliary compasses are elastically installed on the first and second compasses matching with the first and second auxiliary compasses through a coupling with second spring hinges, respectively, such that the first and second auxiliary compasses have elasticity to return to initial mounting positions of the first and second auxiliary compasses.
