 The geometry is the main lead to natural resources exploration.For example, the oil geologists are looking for permeable layers of particular geometry, which allows keeping the oil in place (for instance, the domed shape anticlinal trap).The ore geologists are looking for faults in the sediments – the ways, which deliver the melted mantle materials to the upper crust.Knowledge about underground geometry of the sedimentary basins comes from geological observations, geophysical measurements and from drilling.
