Morphology of saddlerships what are the differences

Recently, an opinion about the manifestation of only folded forms on the Bendigo ore bodies is completely erroneous. For more than the centenary operation of deposits, the following second ore formations were considered conventional: 1) the apophyses, separated upward along the uprising, from the bends of the roof of the ore arches; 2) a series of apophysis, branching from the wings of deposits into the nuclear part of the folds; 3) the apophyses that developed down the fall from the sole of the ore deposit; 4) bundles of flame -shaped low -power veins and veins, extending from the planes of sequencies of jerking ruptures; 5) rare secant veins, healing areas of extended zones of crushing (rice.97). It should be noted that already in the middle of operation (1923.) D. L. Stylel drew attention to the tectonic glink of friction, developed along the hanging side of the wing of some saddle bodies. She fixed the arranged post -layer displacements of the fragile layers of sandstone obliquely along the layers of clay rocks. These movements were accompanied by the formation of cavities in the arches of anticlines, healed by the mineral substance. Most of the living bodies were formed by performing open cavities. However, d. L. Stilvel noted that in 1920. IN. Lindgren was the first to pay attention to the presence in the residential white quartz of the relics of the dark, traces of the almost completely replaced oval fragments of sandstones and the thin linzing interlayers of this breed. In addition to a few generations of quartz, including glass -wool, in ores there were anchorite and other carbonates, sericitis, albith. The number of sulfides is 1-2 %. This is a feast, arsenopritis, occasionally early Shelith, sometimes antimonite, burnite, as well as pyrrhotine, chalcopritis, sphalaris, gallive. Most of the golden are large, more than 1 mm, it is enclosed in quartz. Gold, apparently, associates with fuel and sphalest. However, it is distributed in a quartz unevenly, clearly applying on this residential mineral in the process of intra custody movements. So, individual relatively powerful "arches" Quartz deposits remain indestructible, and, conversely, stray securing apophyses are distinguished by rich ores. Typically, the average gold content in the ore is quite high and changes in different sections of the ore field from 12 to 27 g/t. The pericide changes are weak and manifested near the contacts of the golden -core bodies with the neoplasm of quartz, sericitis, blocked pyrite and arsenopyric. We will not repeat the features of geology in the description of similar, but less large -scale, albeit significant in reserves (dozens of tons of AU) of the ore fields Strel, Klun, as well as other, less important, located near Bendigo. Some deposits of the same type are distinguished by manifestation along with the saddlery chopping golden cores (sometimes deposits of interspersed sulfide ores) . The main of these ore objects is Ballarat. The arches of the saddle deposits in the hinges of ore -bearing anticlines are often replaced. They are confined to sliding planes, which are accompanied by augar substance, and are guided by exactly along the extension of the folds, crossing the layers of terrigenous rocks in the context of.
