The result is an outcrop map in which the observed rock types …A core sample is a cylindrical section of (usually) a naturally-occurring substance. Most core samples are obtained by drilling with special drills into the substance, such as sediment or rock, with a hollow steel tube, called a core drill. The hole made for the core sample is called the "core hole". A variety of core samplers exist to sample ...The whole process is as follows: 1) extract the interpreted model from rock samples measured in a laboratory which focusing properties of S-wave velocity and resistivity; 2) use the interpreted model to compute the geological feature value; 3) reconstruct the compute results to the 3D geological model.
