A method of analyzing a 3D geological structure using a structure index. The method includes the steps of estimating physical property values on common coordinates to calculate two or more physical property models on the same 3D grid (L&#xd7;M&#xd7;N); normalizing the physical property models, thus obtaining normalized physical property models which are then represented in a scatter plot of physical properties; converting distribution positions of the normalized physical property models on the scatter plot of physical properties into type angle (TA) and into type intensity (TI); determining a minimum of TI values, which classifies two or more classes on a scatter plot of the TA and TI values, to be a threshold; and analyzing the 3D geological structure based on a local extreme point and/or points in the scatter plot for the TA and TI using the threshold.

Provided is a portable ultraviolet device for exploring a mineral resource. The portable ultraviolet device for exploring the mineral resource may include a body, a visible component, an ultraviolet lamp assembly, and a darkroom component. The visible component is coupled to the body to pass through the body so that a mineral resource disposed at a lower portion of the body is observed from an upper side of the body. The ultraviolet lamp assembly part is coupled to the body to emit ultraviolet rays onto the mineral resource. The darkroom component is coupled to a bottom surface of the body to surround the visible component and the ultraviolet lamp assembly and defines an external light blocking space having an openable inlet in a lower portion of the body.
