Spectral analysis

If we imagine that the distortion, or to straighten the system layers of popped out of the sea, then, as we already know of many examples, will blur. As a consequence of those or other changes in the sea may again fill the area. This movement of the sea, or transgression, as it is called, entails the formation of new deposits, they will be deposited in horizontal layers in the minds of the former entities. Get the kind of stratification, which is called dissent. Sometimes, stratification disagreement is expressed differently: the newly-formed horizontal layers are located close to the same tilted layers, break off about them, they are known as leaning or ingressivnyh. A special kind of infringements of bedding are shifts, or reset. This word implies movement of rocks occurring in the direction of erupting m vertical or horizontal fractures, usually one side of the crack is descended, or dropped. The difference in height dropped pieces and parts, to retain their previous position, or as they say, the height of relief, often expressed by a few centimeters, but she can take and enormous size of several thousand meters. Due to the terrible pressure that develops when you reset these large masses, falling layers are bent, forming a convex, part of the same reservoir, remains in place, bent in the opposite direction: it turns out so-called folded reset. In connection with cracks are veins. It also cracks in the sediment or solid rock, but filled with some minerals or other rocks, of particular importance for mining are so-called ore veins. Its origin strands are required quite different reasons: in some cases, they filled the igneous flaming mass, moving lower in other cases, minerals, forming a conductor, crystallized from water circulating in the fracture. Sometimes the veins are filled with pebbles, rubble and mud, which is sent back to the surface. Despite the difference in origin, in appearance veins represent the many similarities and are designated by the generic term. In size he lived in the same way as in the way of origin, there are great differences, some of them are very subtle, others achieve considerable power, and some volcanic veins may appear as a separate elevations, if the breed, through which they pass, will be destroyed by the destructive action of water and carried away. Sometimes layered rocks intersect veins in all directions, it can happen that will go live between the two layers, having identical with the strike and dip, a vein is called the reservoir housing. Sometimes the veins occur in droves, most often they can be observed among the volcanic tuff and ash forming cone fire-breathing mountains, and are formed here by filling cracks with lava. Particular attention should be given phenomena we observe at the intersection of two veins, and sometimes parts of the same vein are displaced or discarded in the direction of another, in such cases may determine the relative age of the veins, it is obvious that she lived, which broke the other, and produced a discharge formed later.
