Information Provided by Technique | |

Lithology: | Distribution of density in the subsurface enables inference of rock type. |

Stratigraphic/Structural: | Delineation of steeply dipping formations, geological discontinuities and faults, intrusions and the deposition of silicates due to hydrothermal activity. |

Hydrological: | Density of sedimentary rocks are strongly influenced by fluid contained within pore space. Dry bulk density refers to the rock with no moisture, while the wet bulk density accounts for water saturation; fluid content may alter density by up to 30%.(Sharma, 1997) |

Thermal: | Determination of potential heat source of the system related to the low density signature of molten intrusions. (Bruhn, 2010) |
