Each is measured by different sensors. A photo of the\u003c\/p\u003e\u003cp\u003eapparatus is shown in figure 1. The four core samples G1, a black stone, coarse-grained and compacted with small\u003c\/p\u003e\u003cp\u003emica particles and bigger white quartz inclusions, could be a gabbro and G2 a\u003c\/p\u003e\u003cp\u003egreenish sandstone with small particles and lesser compaction, each unsaturated\u003c\/p\u003e\u003cp\u003eand saturated with water are halved and ¿transported on a stepper motor-driven\u003c\/p\u003e\u003cp\u003etracking system¿ to the sensors. If the rock sample is heterogeneous and the halves\u003c\/p\u003e\u003cp\u003edon¿t accord in their mineral composition, you will have now a potential error source.\u003c\/p\u003e\u003cp\u003eThe samples are laid on the tracking system. A motor pushes them first to a laser,\u003c\/p\u003e\u003cp\u003ewhere the length is measured, than to the gamma source and then to the P-wavevelocity-\u003c\/p\u003e\u003cp\u003esensor. Here you have a second potential error source: When the P-wavevelocity-\u003c\/p\u003e\u003cp\u003esensor presses the samples down for measuring, they were lift on the other\u003c\/p\u003e\u003cp\u003eside. To avoid the lifting the rock samples have to be pressed and so the\u003c\/p\u003e\u003cp\u003emeasurements are not really accurate.
