The invention provides a multifunctional
geological compass. The multifunctional
geological compass comprising a
compass chassis, an upper cover, a rotating mechanism, a streak plate, a soft ruler and a cover plate, an
accommodation space is arranged on the top surface of the upper cover in a concave mode, an opening communicating with the
accommodation space is arranged on the side wall of the upper plate in a through mode, a rotating mechanism is rotatably mounted in the
accommodation space, the streak plate is accommodated in the accommodation space, the streak plate is connected with the rotating mechanism so as to rotate along with the rotating mechanism around a
vertical axis parallel to the vertical direction, the soft ruler is winded on the periphery of the streak plate, one end of the soft ruler is fixed to the periphery of the streakplate, a free end of the soft ruler extends from the opening to outside of the upper cover, and the cover plate is rotatably mounted on one side of the upper cover to open or close the accommodation space. The
geological compass measures rock formation and occurrence of ore veins in the field, and at the same time achieves the primary identification of minerals and measurement of the size of the rock and the
mineral particles and the length of the
vein, effectively reduces the number of field operation tools, and facilitates the field geological workers to carry out the work.
