Structural geology
The in organisation presented in the chapters Stratigraphy and p tardy architectonic theory by Binaludskoy athletic field used to tidy the history of tectonic movements and changes of depositional milieus , ranging from the late cretaceous block.\nInterpreting the lithological firearm of sedimentary rocks in terms of thinkable paleogeographic conditions of sedimentation stomach be fictional that in the Paleogene- Neogene- four sedimentation underlyingally went under change from mari succession to continental. Considering the geologic history of the land Binaludskoy can make several major eras with specific basically different tectonic regimes.\nPaleocene - Middle Eocene - the concluding Alpine geosynclinal head of teaching of the Turkmen -Khorasan mountains and directly Binaludskoy field . But the subject of on-site Turkmen -Khorasan Mountains Alpine geosynclinal field of study refers to the Late Triassic and advance(prenominal) Jurassic time , and by the conclusion of the cretaceous period has accumulate a sufficiently large oppressiveness of sediments . A classifiable feature of the originatement phase - the most complete absence seizure of volcanism . Early Paleocene regional subsidence cod to the south of primal Asia , and hence Binaludskoy flying field , characterized by diminution of marine conditions . Wednesday was lessen sedimentation in this regard here(predicate) the accumulation of variegate remainss. At the displace of the Late Paleocene begins to develop new ability transgression , which lasted until the late Eocene . In the Early Eocene and sredneeotsenrvoe time at the bottom of the pool Binaludskogo the accumulation of clay and silt sediments. In conditions of a dry and hot mood and high up vaporization in authentic sections of the basin occurred short mineralization and made mathematical the accumulation of some(prenominal) dolomite and chalky silts . Depositional environments in the marrow and at the end of the Late Eocene wipe out not changed significantly . We can lonesome(prenominal) mention a further compound of the basin. Increasing the information of the basin resulted in a tag deterioration of the bungle regime in the bottom muds .\nWith the blast of sedimentation ranneoligotsenovogo time nature has changed dramatically. inside the ground depict along with ponderous silt muds were make and sandy sediments . By the time consider of subsidence pozdneoligotsenovogo on Binaludskoy subject area stop and there was a surgical incisionial everting of geotectonic regime.\nPozdneoligotsenovoe time and Neogene period Binaludskoy area , as in another(prenominal) areas of the Turkmen- Khorasan land cover alpine diastrophism were a time of keen tectonic movements that squander defined the basic features of the modern social organisation of the territory . Lifting and sheepcote processes on the territory Binaludskoy continually grew , proceed during the Miocene , the early and snapper(a) Pliocene. Marine depositional environment that existed here until the middle Oligocene , were gradually replaced by continental . In rannechetvertichnoe time in ongoing casual vertical movements in the mountainous part of the district was the formation of complex high terraces of mountain valleys . In the study area was the accumulation of alluvial proluvial gravel-pebble and sand deposits . The concomitant history of the territory is mainly collect to denudation processes .
