Geocache Description:


Tatobity - geologicka expozice
Tatobity

[CZ]

Geologie:
sedimenty a vulkanity permu, kridy a tretihor

Geologicky vyznam:
geologicka lokalita narodniho vyznamu

Mineralogie:
vyskyt stribra, medi, delesitu, fluoritu, jaspisu, karneolu, malachitu, ortoklasu, vapance...

V obci Tatobity, v zahrade malire Jana Dediny, je geologicka presentace hornin z celeho regionu. Na miste lze videt kameny jako je cedic, pisovec, olivinovec melafyr, metagranit a jine.  U kazdeho exponatu je infocedulka, na ktere je napsano odkud pochazi a jeho vlasnosti.

Geologie a geologicke mapovani se stalo detektivni prace, protoze vetsina hornin je ukryta pod povrchem zeme.
Rozmisteni kopcu a udoli muze neprimo naznacovat jake horniny je tvori. Geologove zkoumaji vychozy horniny, vyzbrojeni
topografickymi mapami, kompasem,geologickym kladivem. Pritom sbiraji, urcuji a zakresluji vyskyty hornin do mapy.

Geopark cesky raj je soucasti evropskych geoparku UNESCO od rijna 2005. Doklada vyznam prirodnich podminek pro rozvoj lidske spolecnosti. V okoli Tatobit vytvorily geologicke procesy lozisa piskovcu, stavebniho kamene a vapence. Vapence  vznikly usazovanim na dne jezera, ktere se rozkladalo v okoli Tatobit pred stovkami milionu let v prvohorach.
Specna aktivita, ktera byla vysledkem vystupu horninove taveniny tzv. magmatu, prerusila v

poklidnou sedimentaci v podkrkonosske panvi. Behem vulkanickych vybuchu lava prorazila az na povrch. Visozita tj."hustota" magmatu predurcuje typ sopecne erupce. Magma, ktere obsahuje vstsi mnozstvi kremiku je viskoznejsi a sopky s testovitou lavou vybuchuji s mimoradnou silou. Dulezitou soucasti magmatu jsou plyny. V prubehu erupci mohou unikajici plyny trhat magma na kousky a tak vznikaji pyroklastika. Vulkanicke erupce mohou produkovat krychlove kilometry pyroklastik, ktera vyprodukovala mnoho sopecneho popela. Proudy pyroklastik se pohybuji rychlosti az 200km/h. Nasledne byl popel pomoci srazkove vody zpevnen v mistni basaltoidni az ansdesitoidni horniny. K dalsim usazenym harninam v okoli Tatobit patri sedimenty kridy. Soucasna podoba reliefu je vytvorena tretihorni tektonikou, kterou je spjat i nejmladsi cedicovy vulkanismus.

Deleni geologie:
Dynamicka - zabyva se -  dynamicke pochody na planete. Ty se deli na endogeni ( vulkanicka,                           zemetreseni)  a exogeni ( cinnost vetru, vody, ledovce ... )
Strukturni - studium struktury a jejich popis ( vrasy, zlomy, trhliny... )
Historicka -  sleduje zemskou kuru a deformace na ni
Sedimentarni - studuje sedimentarni horniny - poznani prostredi ve kterem sediment vznikl
Loziskova - zabyva se studiem rud, nerud ( uhli, ropa, zemni plyn )
Regionalni - studium geologicke stavby v dane obasti
Geonika -  nauka na dopad cloveka jeho cinnosti a jim vyvolanych aktivit
Aplikovana - obor geologie vyuzivajici poznatku z mnoha jinych geologickych a technickych oboru

Odpovedi zaslete jako prvni pres profil, na opdoved necekejte. Zalogujte a kdyby neco, tak o me jeste uslysite.

Otazky pro zalogovani:

1) Vyjmenujte 5 hornin ze zahrady
2) jak se jmenuje jeste jinak  kremenny porfyr
3) Dopln vetu z cedule cedic: Lava obsahuje bublinky plynu, .....
4) kolik kamenu je u Ignimbritu 
5) dobrovolny ukol foto: dobrovolne povinne :-)

e rocks are composed. Geologists examine rock outcrops, armed topographical maps, compass, geological hammer. The collect, identify and plotted occurrences of rocks in the map.
Czech Paradise Geopark is part of European Geoparks of UNESCO since October 2005. This illustrates the importance of natural conditions for development human society. There Tatobity geological processes created deposits of sandstone, limestone and building stone. limestone arose settling on the bottom of the lake, which was situated near Tatobity hundreds of millions of years in the Primary.
Specna activity that resulted from the output of the melt rock called magma, interrupted in nladsich Palaeozoic (Permian)
quiet sedimentation basin at the Giant. During volcanic eruptions lava broke through the surface. Visozita ie the "density"
magma determines the type of volcanic eruption. Magma, which contains VSTS amount of silicon is more viscous and pasty lava in the volcano explode with extraordinary force. An important part of the magma gases. During the eruption may be escaping gases
tear the magma into pieces so formed pyroclastic rocks. Volcanic eruptions can produce cubic kilometers of pyroclastic rocks, which produced a lot of volcanic ash.
Currents pyroclastic rocks are moving at speeds up to 200km / h. Subsequently, the ash hardened by withholding water until the local basaltoidni ansdesitoidni rock. Other established harninam around Tatobity include Cretaceous sediments. The current form of relief is created
Tertiary tectonics, which is also connected to the youngest basaltic volcanism.

Responses should be sent via your profile and do not wait for the reply, Login at rest and if it was some problem with the answers, I'll write you





Questions for the log:

1) Name 5 still rocks from the garden
2) what his name is still different quartz porphyry
3) Make sentences signs of basalt: Lava contains bubbles of gas, .....
4) how many stone is in ignimbrite
5) optional tasks photos
